    Technical field
    [0001] The present description refers to filters and, more particularly, fluid filter systems. Background
    [0002] Cartridge-type fluid filters, such as, for example, fuel or lubricant filters associated with an engine, typically include a replaceable filter element contained within a canister that is threadably engaged to the engine. The unfiltered fluid, for example fuel or lubricant, is received by the filter through an inlet port, the particles are removed from the unfiltered fluid through the filter element, and the filtered fluid is delivered to the engine through an outlet port. . The filter element often includes a filter medium generally cylindrical, for example, of fabric or other porous material, loaded into the cup through one or more lids, such that the unfiltered fluid flows through the filter medium. filter in a generally radial direction. A lid typically loads and / or positions the filter medium inside the cup and in relation to the inlet and outlet holes. Fluid filters usually also include one or more seals that watertightly separate the inlet and outlet holes to reduce or eliminate unfiltered fluid from passing through the filter medium.
    [0003] Typically, the filter elements of such fluid filters are often replaced to reduce the pressure drop through the filter medium, prevent deterioration of the seals, and / or otherwise, try to ensure that the fluid filter operate as desired. To replace a filter element, the bowl is normally unscrewed from the engine, the seals between the inlet and outlet of the flows are detached, the old filter element is removed from the cup, a new filter element is inserted, and the cup is threaded back into the engine. . An operator replacing a filter cartridge can prime (“prime”) the cup with fluid to avoid and / or reduce the air trapped inside the fluid system.
    [0004] This priming fluid is often used before and / or unfiltered cup priming fluid may require great care to prevent the priming fluid from being placed on the downstream side, that is, the side of the filtered fluid from the filter medium. In addition, proper replacement of the seals, both old seals and new seals, when replacing the filter cartridge is desirable to provide sufficient sealing between the inlet and outlet holes and thereby reduce the unfiltered fluid from passing through the medium filter. Unfiltered and / or priming fluid downstream of the filter medium, either due to insufficient sealing and / or from priming by the operator, can result in damage to one or more engine components during operation.
    [0005] US patent No. 6,554,140 ("the '140 patent'), granted to Steger. Jr. et al. describes a filter arrangement including an outer seal that forms a seal between an outer shell and a filter base and an inner seal that forms a seal between a cover and the filter base. The filter arrangement is threadably connected to the filter base by means of a nut plate (“nutplate”) that compresses the external seal against the filter base. The filter arrangement also includes a filter element where the unfiltered fluid, from an unfiltered fluid passage, flows into a radial space between the outer shell and the filter element, the unfiltered fluid seeps through the filter element inside from an internal passage, and the resulting filtered fluid flows into a filtered fluid passage.
    [0006] The '140 patent can provide a seal between the filter arrangement and the filter base with the outer seal, and can provide a seal to minimize fluid leakage in a connection between the filtered fluid passage and the internal passage with the internal seal. The '140 patent may, however, require several components to achieve these seals, complicating assembly and alignment, which may require precise manufacturing tolerances and / or reduce the sufficiency of the sealing potential.
    [0007] Additionally, reconnecting the filter arrangement of the '140 patent to the filter base, and installing the internal and external seals, may require a single nut plate with specific geometry to ensure its correct alignment with the base of the filter. filter and again the proper sealing and reconnection of the filter arrangement. The present description is aimed at overcoming one or more of the aforementioned disadvantages. Summary of the invention

    [0022] The container 14 can include an outer wall 28 and an extreme wall 30. The outer wall 28 can be substantially cylindrical in shape, and can include external threads 31 configured to threadably engage internal threads 21 included in the base 12 The extreme wall 30 can be arranged at one end of the external wall 28 opposite the external threads 31. The external wall 28 and the extreme wall 30 can generally define an internal cavity configured to contain the filter arrangement 16. It is contemplated that the internal threads 21 and external threads 31 can each, respectively, extend either clockwise or counterclockwise. It is also contemplated that the container 14 may include a conventional drain hole (not referenced) that can be configured to facilitate the drainage of fluid from the container 14 and / or may include any conventional relief valve (not shown) to limit a system pressure. fluid from the fluid system. It should be understood that the coupling between the internal threads 21 and external threads 31 and the friction resulting from the coupling between them, are well known in the art and thus will not be described below.
    [0023] The filter arrangement 16 can include a first cap 32 and a filter means 34. The first cap 32 can be arranged adjacent to the base 12, and can be configured to load the filter means 34 inside and in relation to to container 14 and to provide seals between base 12 and container 14 and between inlet port 24 and outlet port 26, respectively. The filter means 34 can be configured to retain particles and / or other particles in suspension within a fluid, and can include a generally cylindrical shape arranged around and extending along the longitudinal geometric axis 18. The filter arrangement 16 may also include a sleeve 36 and a second cap 38. The sleeve 36 may include a generally cylindrical tube, radially disposed inside or radially outside the filter means 34, and may include one or more perforations 37 configured therein. allow fluid to flow through it, for example, from filter medium 34 to an internal space 40 (as shown in figure 1). A first end of the sleeve 36, disposed adjacent to the base 12, can be engaged with, for example, contacting, the first cap 32 and a second end of the sleeve 36, disposed adjacent to the extreme wall 30 of the container 14, can be engaged with, for example, contact, second cap 38. The second cap 38 can be arranged adjacent to the extreme wall 30 of the container 14 and can be configured to load the filter medium 34 inside, and in relation to the container 14. It is contemplated that the second cover 38 can engage an internal surface of the outer wall 28 and / or the extreme wall 30 of the container 14. It should also be contemplated that the filter medium 34 can include any filter material and / or medium known in the art, such as, for example, example, fabric or other porous material, and may or may not be pleated. It is also contemplated that the first and second caps 32, 38 and sleeve 36 can be made of any suitable material, such as, for example, a polymer or other plastic, and can be injection molded. It is further contemplated that the perforations 37 can include any shape, size, and / or quantity, and the sleeve 36 can be selectively omitted.
    [0024] With reference to figures 1 and 2, the first cap 32 may include an external seal member 42 configured to provide a fluid seal between the base 12 and the container 14, and an internal seal member 44 configured to provide a fluid seal between inlet port 24 and outlet port 26. Specifically, the first cap 32 may include a body having a generally circular shape formed on the first wall 46, a generally cylindrical shape on the second wall 48 disposed adjacent to a portion radially outer, for example, an outer edge, of the first wall 46, and a third wall 50 generally cylindrical in shape adjacent the radially inner portion, for example, an inner edge, of the first wall 46. The first wall 46 may include a plate generally perpendicular to the geometric axis 18.
    [0025] The second and third walls 48, 50 can generally extend towards, that is, they can generally be parallel to the longitudinal geometric axis 18 in a direction A, for example, towards the extreme wall 30 of the container 14 The first cap 32 may also include a generally cylindrical flange 52, disposed between the inner and outer portions of the first wall 46 and generally extending along the longitudinal geometric axis 18 in a direction B, substantially opposite the direction A, for example, away from the extreme wall 30 of the container 14. The first lid 32 may also include a fourth wall 54 generally circular in shape radially disposed outside the first wall 46 by means of a first plurality of arms 56 (as illustrated more clearly in figure 2) and, generally, extending along the longitudinal geometric axis 18 in direction A. Arms 56 can include any shape, length and / or quantity, and can define openings 57, inc including any shape, length and / or quantity, between those adjacent to them. The first cap 32 may also include a fifth wall 58 generally extending radially outwardly from a first end of the fourth wall 54 in a direction generally perpendicular to the geometry axis 18. A second end of the fourth wall 54 can be configured to fit in the interior of a groove 60 formed within an internal surface of the base 12. It is contemplated that the groove 60 can be substantially complementary in shape to the circumferential shape of the fourth wall 54. It is also contemplated that an axial end of the outlet hole 26, arranged adjacent to cover 32, it can contact the first wall 46 radially at a location within the flange 52, that is, radially close to the geometry axis 18, and may include a chamfer, a fillet, a taper on an internal and / or external surface , and / or include any other shape configured to allow the inner sealing member 44 to move beyond the axial end of the orifice d and outlet 26 when, for example, an operator replaces filter arrangement 16, as will be described in more detail below. It is further contemplated that the cap 32 may or may not be fixedly connected to the filter medium 34 and / or may include any device configured to establish fluid seals in relation to the base 12 and an outlet port 26, such as, for example , an adapter configured to interconnect a top plate and / or other base cover 12 through a threaded connection.
    [0026] The outer sealing member 42 can be arranged adjacent and configured to wrap the most radially outer edge of the fifth wall 58, and can be integral with the fifth wall 58 and thus the first cap 32. Specifically, the member of external seal 42 can be configured to provide a fluid seal in relation to the base 12 and the container 14 and thus an external environment, as a result of being compressed between an axially facing surface of the base 12 and an axially facing surface of the container 14. An axially facing surface may, for example, include a surface that is not predominantly parallel to the geometry axis 18, for example, a surface that can be generally perpendicular to the geometry axis 18. The outer sealing member 42 may include a surface external circumferential having first and second portions thereof, respectively, configured to establish axially facing sealing interfaces with respect to, for example, the surface axially facing the base 12 and the axial surface facing the container 14. Furthermore, the base 12 can include a depression (not referenced) on an internal surface of the same configured to be complementary to the shape of the external sealing member 42.
    [0027] The internal sealing member 44 can be radially disposed within the flange 52 and radially outside the outlet port 26 and can be integral with the flange 52 and thus the first cap 32. Specifically, the sealing member inner 44 can be configured to provide a fluid seal between the inlet and outlet ports 24, 26 as a result of being compressed between an inner surface radially facing flange 52, and an outer surface radially facing outlet port 26. A radially confronting surface may, for example, include a surface that is not predominantly perpendicular to the geometric axis 18, for example, a surface that can generally be parallel to the geometric axis 18.
    [0028] The inner sealing member 44 can include a circumferential outer surface having first and second portions thereof, respectively, configured to engage an axially facing surface of the first wall 46 and a radially facing surface of the flange 52. In addition, the surface outer circumferential portion of the inner sealing member 44 may include a third portion thereof configured to establish a sealing interface radially confronting the outlet port 26. It is contemplated that the flange 52 may at least partially surround at least a portion of the outlet orifice 26 and inner sealing member 44, respectively, so that inner sealing member 44 can be compressed between them, and flange 52 can help maintain the radially confronting sealing interface established by inner sealing member 44 by resistance to movement of the inner sealing member 44 radially outward and away the outlet port 26 which can be caused, for example, by the forces generated by the communicated fluid from the inlet port 24 colliding with the internal sealing member 44.
    [0029] At least a portion of the inner sealing member 44 can extend axially along the longitudinal geometry axis 18, in the B direction, at an axial distance greater than the outer sealing member 42 which can extend axially along the geometric axis longitudinal 18, in direction B. That is, at least a portion of internal sealing member 44 can extend at a first axial distance C along longitudinal geometry axis 18 from a first end of the filter medium 34 (shown according to line D in figure 1), the outer sealing member 42 can extend at a second axial distance E along the longitudinal geometric axis 18 from the first end of the filter medium 34 (line D), and the first axial distance C can be greater than the second axial distance E. Additionally, at least a portion of the inner sealing member 44 may extend at a first axial distance F along the longitudinal geometric axis 18 from a the axial end surface of the container 14 (shown in line G in figure 1), the outer sealing member 42 can extend at a second axial distance H along the longitudinal axis 18 from the end axial surface of the container 14 (line G), and the first axial distance F can be greater than the second axial distance H. As well, the axial relationship between the inner and outer sealing members 42, 44 and the body of the first cap 32 can improve and / or help directing the flow of fluid from the inlet port 24 towards the openings 57, and then towards the filter medium 34, while maintaining the proper seal between the inlet and outlet holes 24, 26.
    [0030] It is contemplated that both internal and external sealing members 42, 44 can generally be cylindrical in shape around the longitudinal geometric axis 18, and can include any shape of cross section, for example, the external sealing member 42 can include a substantially oval or round shape and / or internal sealing member 44 may include a substantially square or rectangular shape. It is also contemplated that the external sealing member 42 can be compressed, according to a function of the axial distance between the extreme surfaces axially confronting the base 12 and the container 14, when threadably engaged, and that the internal sealing member 44 can be compressed according to a function of the radial distance between the inner surface radially facing the flange 52 and the outer surface radially facing the outlet port 26. It is also contemplated that the outer sealing member 42 can establish sealing interfaces axially facing, for example, a sealing interface that substantially blocks fluid from flow along an axial surface facing with respect to base 12 and / or container 14, as well as a radially facing sealing interface, for example, a sealing interface that substantially blocks the flow fluid along a radial surface facing the base 12 and that the inner sealing member 44 can establish radially facing sealing interfaces with respect to flange 52 and / or outlet port 26 as well as being devoid of any axially facing sealing interfaces. It is further contemplated that the inner sealing member 44 can be radially compressed and can be axially expanded, displaced, or tilted, as a result of being radially compressed, but it may not be axially compressed, i.e., devoid of axial compression. It is further contemplated that the external sealing member 42 can be axially compressed in relation to the base 12, at any radial location in relation to the internal sealing member 44. As such, the internal sealing member 42 radially compressed, can reduce the tolerances of manufacture and / or assembly in relation to the length and circumferential dimension of the outlet orifice 26 and / or the cap 32 while maintaining the proper seal between the inlet and outlet orifices 24, 26.
    [0031] As shown in figure 2, the first cap 32 can include a plurality of first recesses 62 formed in the fifth wall 58. The first recesses 62 can include openings through which the outer sealing member 42 can extend. The first cap 32 can also include a plurality of second recesses 64 formed within the second flange 52. The second recesses 64 can include cavities into which the inner sealing member 44 can extend. The outer and inner sealing members 42, 44 can, respectively, extend into the first and second recesses 62, 64 during a method of manufacturing the first cap 32. Specifically, the first cap 32 can be formed by injection of molten material into one or more more first molds, and allowing the molten material to solidify, that is, formed by one or more injection molding processes. The shape and contour of the first molds can provide one or more characteristics of the first lid 32, such as, first, second, third, fourth and / or fifth walls 46, 48, 50, 54, 58, flange 52, projections 56 and / or first and / or second recesses 62, 64. Within the first mold and / or within one or more additional molds, the outer and inner sealing members 42, 44 can be formed by injecting molten material into the interior of the additional molds and allowing the molten material to solidify, that is, through one or more injection molding processes, to form external and internal sealing members 42, 44, respectively, adjacent to the fifth wall 58 and the flange 52. As such, the material cast of the outer and inner sealing members 42, 44, can, respectively, flow into the first and second recesses 62, 64 and can integrally connect and form a connection with the outer and inner sealing members 42, 44 and the rest of first cap 32, respective mind. It is contemplated that the first and second recesses 62, 64 may include openings, cavities, any quantity, any shape, and / or may or may not be uniformly spaced around the longitudinal geometric axis 18. It is also contemplated that cover 32 may or may not solidify completely before the outer and inner sealing members 42, 44 are formed.
    [0032] Again with reference to figures 1 and 2, the first cap 32 may also include an anti-fill device 66, configured to reduce and / or prevent unfiltered fluid from flowing into the internal space 40 during a priming process. The device 66 may include a plurality of wall portions 68 each having a first end connected to the first wall 46 and extending therefrom in the direction B. The first wall portions 68 may define a plurality of openings 70 spaced between those adjacent to the portions wall 68. That is, the wall portions 68 can establish a first radially facing wall having openings 70 therein. Device 66 may also include a cover portion 74 attached to the wall portions 68 at the ends thereof, opposite the ends attached to the first wall 46. Device 66 may also include a generally cylindrical wall 72 radially disposed within the wall portions 68 in relation to the longitudinal geometric axis 18. Wall 72 can be connected at one end of it to the first wall 46, and can extend in direction B. The end of wall 72 opposite the end connected to the first wall 46, can be axially spaced at any distance from an inner surface of the covering portion 74 and the radially outer surface of the wall 72 can be radially spaced at any distance from the inner radial surfaces of the wall portions 68. It is contemplated that when the filter system of fluid 10 is mounted, the device 66 can extend inside and can be radially surrounded by the outlet port 26. It is also it is contemplated that the anti-fill device 66 can be omitted, and the first cap 32 may alternatively include one or more openings configured to allow fluid flow from the internal space 40 towards the outlet holes 26.
    [0033] An alternative embodiment of the lid is illustrated in figures 3 to 5. Figure 3 illustrates a first alternative embodiment of the lid 32 disposed in a container 14 connected to a base 12. Such a lid 32 can include a first wall 46 (first member), a second wall 48 (side wall), a third wall 50, a fourth wall 54 (external wall), a plurality of arms 56, a fifth wall 58 (protrusion), a flange 52 and internal and external sealing members 44, 42. Similar to the embodiment of figures 1-2, the inner sealing member 44 may include a circumferential outer surface having first and second portions thereof, respectively, configured to engage an axially facing surface 32 and a radially facing surface to the flange 52. Figure 5 illustrates a sectional view of the cover to which the plurality of second recesses 64 formed within the flange 52 can be seen. The second recesses 64 can include cap cavities 90 into which the inner sealing member 44 can extend. Such extensions of the sealing member 44, regardless of shape, can be referred to as dovetails ("dovetails") 88.
    [0034] Figures 6-7 illustrate yet another alternative embodiment of the lid 32. Figure 6 illustrates a first alternative embodiment of the lid 32 arranged on a container 14 attached to a base 12. This alternative embodiment does not include the anti-fill device seen in the others achievements. Such a lid 32 can include a first wall 46 (first member), a second wall 48 (side wall), a third wall 50, a fourth wall 54 (outer wall), a plurality of arms 56, a fifth wall 58 (overhang) , a flange 52, and internal and external sealing members 44, 42. In this embodiment, the internal sealing member 44 can include an external circumferential surface having first and second portions thereof, respectively, configured to engage a surface axially facing the cover. 32 and a surface radially facing the cap 32, that is, the flange 52. In this embodiment, the flange may be part of the cap, but unlike the first alternative embodiment, the flange 52 is not configured to extend in a B direction to above from the first wall 46. Figure 7 shows a sectional view of the lid 32, from which the plurality of second recesses 64 formed within the flange 52 and the plug joints 88 po can be seen.
    [0035] With respect to each of these alternative embodiments shown in figures 3 to 7, each of the arms 56 can be of any width and can include a fin portion 76 extending in direction A. The fin portion 76 can be adjacent to the second wall 48. As shown in figures 3 to 7, the second wall 48 can have an inner edge 78 and a second lower wall surface 80, which can be inclined or curved. The inner edges 78 and the filter medium side 34 can extend in a generally parallel relationship from the top of the filter medium side to where the inner border 78 intersects the second lower wall surface 80. The fin portion 76 can it can also be totally or partially continuous with the second wall 48, and can also extend in direction A from all or part of the bottom side 82 of the fifth wall 58. The fin portion 76 can have first and second lower surfaces 84, 86 which together, they form a first reflex angle α. The reflex angle can be less than about 270 ° but more than 180 °. The arms 56 (including the fin portion 76), second wall 48, fourth wall 54 and fifth wall 58, can be separate components joined together or can be integral with each other and, alternatively, with the first wall 46. The arms they can be evenly spaced around the second wall 48, but it doesn't have to be. The number of arms and the spacing around the side wall may vary.
    [0036] The first lower surface 84 of each fin portion 76 may intersect with the second wall 48. The first lower surface 84 may be substantially perpendicular to the second wall 48 or may form an acute angle with the second wall 48. It is also contemplated that a portion of the first lower surface 84 can be curved or non-linear, and may not intersect the second wall 48 at an angle.
    [0037] In one embodiment, a method of installing a filter 30 in a fluid filter system 10 comprising a base 12, a cup 14, the filter 30 comprising a first cap having a second bottom surface 86 and including first and second annular seals 42, 44, a sleeve 36 and a filter means 34. The method comprises guiding the filter 16 inside the container 14 by positioning the second lower surface 86 of the lid 38 next to an inner wall 92 of the container 14, slide the filter 16 inside the container 14 until the first seal 42 contacts the container, fix the container 14 on the base 12 until the base 12 engages the top 94 of the cover 38 and a first radial seal is established between the base 12 and the second seal 44, and after the first radial seal is established, continue fixing the container 14 on the base 12 until a second radial seal is established by the first seal 42 between the cover 38 and the base 12, and a first axial seal is established between the first seal 42 and the container 14. An axial seal is a seal that is parallel to the longitudinal geometric axis. The arrangement of the internal and external seals on the cover helps to ensure that the cover is adequately sealed against leakage. Since the inner seal is not able to be visually observed during the seal, it is beneficial if this seal is arranged in such a way that it must be completely sealed before the outer seal is completely sealed. By arranging a portion of the inner sealing member 44 around the first axial distance C (see figure 3) from a first end of the filter means 34 (shown as line D in figure 3) and arranging the outer sealing member 42 from so that it only extends to the second axial distance E from the first end of the filter medium 34 (line D), it helps to ensure the proper complete seal of the inner seal 44 before the complete seal of the outer seal 42. Industrial applicability
    [0038] The fluid filter system described can be applicable to filter any type of fluid, and can provide a seal between an unfiltered fluid flow and a filtered fluid flow without the need for numerous components in a complex and / or components that require high manufacturing tolerances. The operation of the fluid filter system 10 is explained below.
    [0039] With reference to figure 1, the fluid filter system 10 can receive unfiltered fluid in the inlet port 24, for example, a first flow region, from one or more components upstream of a fluid system . Unfiltered fluid can flow from inlet port 24 radially outwardly and can be directed through the first cap 32 to flow towards openings 57. Unfiltered fluid can flow through one or more openings 57 in, for example. for example, a substantially axial direction through the first cap 32, and into the radial space between the container 14 and the filter medium 34. The unfiltered fluid can then generally flow radially through the filter medium 34, and the filter medium 34 can retain the particles suspended within the unfiltered fluid, thereby filtering the fluid. The filtered fluid can then flow through the openings 37 and thus through the sleeve 36 and into the space 40. The filtered fluid can also flow from the internal space 40 through the device 66, for example, through the wall 72, into the space between the wall 72 and the wall portions 68, and through the openings 70. The filtered fluid can still flow into the outlet port 26, for example, a second flow region, and towards one or more more components downstream of the fluid system.
    [0040] It may be desirable to replace the filter arrangement 16 since the filter medium 34 may be saturated with trapped particles, and the inner and outer sealing members 42, 44 may be deteriorated, a maintenance period has elapsed, and / or due to any other logical reason known in the art. An operator can unscrew container 14 from base 12, extract old or used filter assembly 16 from inside container 14, and insert a new or unused filter assembly 16 into container 14. As as such, the outer and inner sealing members 42, 44 can be detached as the old first cap 32 is removed with the old filter arrangement 16. The operator can insert a new filter arrangement 16 into the container 14 and can re-thread the container 14 to the base 12 and, like the outer and inner sealing members 42, 44 can be fitted according to the first new cap 32 if aligns with the base 12. It is contemplated that the operator can remove part or all of the fluid retained inside the container 14 together with and / or after removing the old filter arrangement 16. It is also contemplated that the operator can replace any one or more elements of the filter arrangement 16, for example, he can replace only the filter medium 34 and cover 32, instead of replacing all the elements of the filter arrangement 16.
    [0041] The operator can prime the container 14 after inserting a new filter arrangement 16 and before re-threading the container 14 to the base 12. As such, the operator can fill the radial space between the container 14 and the filter medium 34 with fluid by, for example, leakage of fluid through the openings 57 and / or over the top of the surface of the first cap 32, for example, the surface of the wall 46 facing and / or exposed to the inlet 24. The priming may or may not be filtered, and device 66 may reduce and / or prevent fluid from entering the internal space 40. Specifically, as the operator spills the priming fluid, some of the priming fluid may flow radially outward towards the openings 57, through openings 57, and into the radial space between the filter medium 34 and the container 14. If an operator spills an excessive volume of priming fluid through the openings 57 and thus overflowing the radial space between the container 14 and the filter medium 34, if the operator does not directly pour the priming fluid through the openings 57 but generally spills the priming fluid on the first cap 32, and / or as a result of operator negligence, for example , dripping or splashing, part of the priming fluid can flow radially inward along flange 52 and / or be deposited radially inside flange 52. Such deposited fluid can flow towards device 66 through openings 70 and can be prevented from flowing into the internal space 40 through the cylindrical wall 72.
    [0042] It is contemplated that the cylindrical wall 72 can extend axially from the first wall 46 to a greater distance than the distance that the flange 52 extends axially from the first wall 46, and that openings 57 can be arranged axially more closer to the container 14 than to the flange 52. As such, the priming fluid can flow radially outwardly along the flange 52, through the openings 57, and into the space between the container 14 and the filter medium 34 or wall overflow 28 of the container 14, instead of overflow of the cylindrical wall 72 and the flow into the inner space 40. It is also contemplated that some priming fluid can be held radially between the flange 52 and the cylindrical wall 72, in which it can be retained inside the outlet port 26 after the container 14 and the filter arrangement 16 are interconnected with the base 12. The amount of such retained priming fluid can be significantly m less than an amount that can otherwise flow into the internal space 40 if device 66 is omitted. It is further contemplated that the relative axial relationship between the outer and inner sealing members 42, 44 can additionally assist or improve the flow of fluid towards the openings 57 during priming by radially stimulating the fluid outward to flow from from the internal sealing member 44 towards the external sealing member 42 and resisting the flow of radial fluid to the interior from the external sealing member 42 towards the internal sealing member 44.
    [0043] As the container 14 and the filter arrangement 16 are interconnected with the base 12, the external sealing member 42 can form a seal between the base 12 and the container 14, for example, between the fluid filter system 10 and the environment, and the internal sealing member 44 can form a seal between the inlet port 24 and the outlet port 26, for example, between unfiltered and filtered fluid streams. Specifically, the outer sealing member 42 can be positioned on top of the outer wall 28 and compressed according to a function of the container 14 being threadably engaged with the base 12 and can, for example, be compressed between the container 14 and the base 12 to establish one or more axially facing sealing interfaces for, for example, a sealing face against a surface axially facing the container 14 and / or base 12. It is contemplated that the outer sealing member 42 can be compressed against one or more both container 14 or base 12, and that the external sealing member 42 can additionally and / or alternatively define a sealing interface radially confronting with one or both container 14 or base 12. Additionally, the internal sealing member 44 can be aligned with the outlet port 26 and can move after one end of it, as the container 14 is threadably engaged with the base 12, be compressed as a function the distance between the inner surface radially facing the flange 52 and the outer surface radially facing the outlet port 26, and can, for example, be compressed between them to establish a sealing interface of radially facing for, for example, a face seal against a radial surface of the outlet port 26.
    [0044] Since the outer and inner sealing members 42, 44 can be integral with the first cap 32, the container 14 and filter arrangement 16 can be sealed in relation to the base 12, and the fluid filter system 10 may include a less complex fluid filter system. In addition, since the first cap 32 includes the device 66, the unfiltered fluid can be reduced or prevented from flowing into the internal space 40 during priming of the container 14 during the filter replacement.
    [0045] It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed fluid filter system. Other embodiments will be evident to those skilled in the art from considering the specification and practice of the method and device described. It is to be understood that the specification and examples are considered as examples only, with a true scope being indicated by the following claims and their equivalents.
