    Filtration systems that can not operate without a filter are described. The filtration systems (100) include a valve (126) disposed in a filter housing. The valve (126) is normally pushed into the closed position when a filter cartridge (104) is not inserted into the filter housing, so that a fuel in the filter housing can not flow. up to an internal combustion engine. The filter cartridge (104) includes a primary filter element (108) and a hydrophobic strainer device (118). The hydrophobic strainer device (118) comprises an actuator finger of the valve (134) which cooperates with the valve (126) and places it in the open position when the hydrophobic strainer device (118) is housed in the operating position in the filter housing. In this way, fuel can pass from the filter housing to the fuel injectors only when the hydrophobic strainer device (118) is disposed in the operating position in the housing. The hydrophobic strainer device (118) is a separate piece from the primary filter element (108), allowing the primary filter element (108) and the hydrophobic strainer device (118) to be replaced separately.

    FILTER CARTRIDGE WITH FILTER ELEMENT
    REMOVABLE
    The present invention relates to filtration systems.
    Internal combustion engines burn fuel, for example diesel fuel, gasoline, ethanol, etc., to operate or drive an apparatus, for example a motor vehicle. Impurities such as water, dust and other particulate matter may damage an internal combustion engine if they are not removed prior to combustion. For example, standardized fuel purity levels for an internal combustion engine have been established to ensure a long engine life, prevent a decline in performance, and ensure compliance with emission standards. appropriate. Many internal combustion engines rely on fuel filtration systems to provide pure and substantially water-free fuel to the internal combustion engine and its components, for example fuel injectors. Fuel filtration systems generally include a filter element that retains particles such as dust and debris contained in the fuel and separates the dispersed water particles that may be present in the fuel, and then evacuates them.
    The filter elements of fuel filtration systems generally have a limited life. As the fuel passes through a filter element, the filter element intercepts the impurity particles until the clogging of the filter element reaches a critical threshold or, in other words, until clogging becomes such that the fuel filtration system is no longer able to provide pure fuel to the internal combustion engine. As a result, the filter elements are periodically replaced by replacement filter elements. In order to save money, some internal combustion engine users and repairers replace the original filter elements with non-genuine replacement filter elements, such as unbranded or used filter elements, which are not certified to provide filtered fuel. complies with purity level standards. In addition, some users and repairers simply remove the original filter element when the original filter element becomes clogged and attempt to operate the internal combustion engine without replacement filter element. In each case, the fuel supplied to the internal combustion engine may not meet the required fuel purity criteria and may damage the internal combustion engine or adversely affect the ecosystem, for example by exacerbating emissions. In addition, multi-stage filter cartridges are often discarded and replaced, although some stages have a longer service life than other stages, resulting in unnecessary replacement of some floors.
    According to a first aspect, the invention relates to a filtration system for filtering a fluid and supplying the filtered fluid to a member of an internal combustion engine. The filtration system comprises a housing and a column provided with a valve, the valve being pushed to a closed position which prevents the flow of fluid through the valve. A filter cartridge is removably disposed within the housing, the filter cartridge including a primary filter element and a strainer device. The primary filter element comprises a filter medium for filtering the fluid, a first plug and a second plug. The strainer device comprises a strainer and a plug portion. The plug portion includes an actuator finger of the valve that cooperates with the valve to move the valve to the open position and allow fluid to flow through the valve when the filter cartridge is in the operating position in the housing. The actuating finger of the valve may be part of the strainer or may be an independent part. The invention will be better understood from the detailed study of some embodiments taken by way of nonlimiting examples and illustrated by the appended drawings in which: - Figure 1 is a sectional view of a filtration system according to a embodiment, - Figure 2 is an exploded sectional view of the filter cartridge of the
    3 is a closeup cross-sectional view of the strainer device of the filter cartridge of FIG. 1; FIG. 4 is a close-up sectional view of the filtration system of FIG. 1; FIG. the filter cartridge being inserted into the operating position in the housing, - Figure 5 is a closeup sectional view of the valve of the filtration system of Figure 1, the filter cartridge being inserted into the operating position in the housing and Figure 6 is a sectional view of a filtration system according to another embodiment.
    FIGS. 1 to 6 show filtration systems that can not operate without a filter. The filtration systems include a valve disposed in a filter housing. The valve is normally pushed into the open position when there is no filter cartridge in the filter housing, unless there is fluid flow, in which case the fluid brings the valve into the closed position. When the valve is in the closed position, fuel from the interior of the filter housing can not flow to the fuel injectors of the internal combustion engine. The filter cartridge includes a primary filter element and a hydrophobic strainer device. The hydrophobic strainer device comprises a valve actuating finger which cooperates with the valve and opens the valve when the strainer device is disposed in the filter housing in the operating position. In this way, the fuel can pass from the filter housing to the fuel injectors only when the strainer device is housed in the operating position in the housing. The strainer device is a separate part of the primary filter element to separately replace the main filter element and the strainer device.
    A sectional view of a filtration system 100 according to one embodiment is shown in Figure 1. The filtration system 100 has a lower shell 102 of a filter housing. The filtration system 100 further includes a removable filter cartridge 104 removably disposed within the housing. In the embodiment illustrated in Figure 1, the filter cartridge 104 has a substantially cylindrical shape. As shown in Fig. 1, the filter cartridge 104 is partially inserted into the lower shell 102 on a column 106. The filter cartridge 104 comprises a primary filter element 108. The primary filter element 108 comprises a filter medium (for example a paper-based filter media, a foam-based filter media, a cotton-based filter medium, a pleated filter medium, etc.) which filters a liquid such as fuel. The primary filter element 108 comprises a dirty face 110 and a clean face 112. The dirty face 110 receives the liquid to be filtered and the clean face 112 passes the filtered liquid. A first end of the filter media is secured by a first plug 114 and a second end of the filter media is secured by a second plug 116. The first plug 114 and the second plug 116 are both open.
    The filter cartridge 104 further includes a removable strainer device 118. The strainer device 118 comprises a strainer 120. The strainer 120 is a hydrophobic strainer. The strainer 120 intercepts, collects and discharges the water remaining in the fuel after the fuel passes through the primary filter element 108. In the embodiment of Figure 1, the strainer 120 has a substantially cylindrical shape so as to it can be inserted over the column 106 and inside the primary filter element 108. The strainer 120 can also be an independent part. In this way, the strainer 120 is placed on the clean face 112 of the primary filter element 108. The strainer device 118 is placed inside an opening in the primary filter element 108 and the column 106 is placed in an opening in the strainer device 118 when the filter cartridge 104 is in the operating position. In other words, the primary filter element 108, the strainer 118 and the column 106 are nested within each other when the filter cartridge 104 is in the operating position.
    The strainer device 118 includes a plug portion 122. In some arrangements, the plug portion 122 is secured to the strainer 120 by an interlocking assembly. In other arrangements, the plug portion 122 is integral with the strainer 120. The strainer device 118 is removably housed in the filter cartridge 104. The plug portion 122 removably assembles. with the second plug 116 of the primary filter element 108. The assembly of the plug portion 122 with the second plug 116 can be accomplished by an interlocking assembly, a snug fit assembly, a friction fit, or the like. A seal 124 may be interposed between the plug portion 122 and the second plug 116 to hermetically seal the dirty face 110 from the clean face 112.
    Still with reference to Figure 1, the filtration system 100 comprises a valve 126. The valve 126 is a valve blocking the filtration system in the absence of filter element. The valve 126 is placed at one end of the column 106. The valve 126 comprises a ball 128 pushed towards an orifice 130 of the valve 126. The ball 128 has dimensions and a shape for closing the orifice 130 hermetically. , the valve 126 is pushed towards the closed position (the closed position is defined as the position in which the ball 128 prevents the fluid from passing through the orifice 130) which prevents the flow of fluid through the valve 126. The port 130 opens into a fuel supply pipe 132 which supplies fuel filtered by the filtration system 100 to a member of an internal combustion engine such as a fuel injector. When the valve is in the closed position, the fuel can not pass from the filter housing to the internal combustion engine. The plug portion 122 of the strainer device 118 includes an actuating finger of the valve 134. As described in more detail below, when the filter cartridge 104 is fully inserted into the housing and is in an operating position in the the housing, the actuating finger of the valve 134 pushes the ball 128 away from the orifice 130, thereby opening the valve 126 and allowing a flow of fuel in the supply pipe 132 in fuel.
    Figure 2 is an exploded sectional view of the filter cartridge 104. The filter cartridge 104 includes the primary filter element 108 provided with the first plug 114 and the second plug 116. In some arrangements, the primary filter element is supported. by a support member 202. The support member 202 provides greater rigidity to the primary filter element 108 so that the primary filter element 108 does not collapse under the effect of the pressure of the filtered filter fluid. through the primary filter element 108. The filter cartridge 104 also includes the removable strainer device 118. The removable strainer device comprises a strainer 120 and a plug portion 122. The plug portion 122 includes the actuator finger of the Valve 134. As mentioned above, the primary filter element 108 and the strainer device 118 are replaceable separately.
    FIG. 3 shows a closeup cross-sectional view of the strainer device 118. As discussed above, the strainer device comprises the strainer 120 and the plug portion 122. The plug portion 122 comprises a finger Actuation of the valve 134. In addition, a seal 124 may be placed around the plug portion 122 to seal between the plug portion and the second plug 116 of the filter cartridge 104. As shown in FIG. 3, the operating finger of the valve 134 is hollow and is traversed by a passage 302 from an inner portion of the plug portion 122 to an outer portion of the plug portion 122. The strainer 120 comprises a plurality of 304 strainer panels supported by support members 306. Each strainer panel 304 comprises a hydrophobic strainer fabric web. In another possible arrangement, a single strainer panel wraps the strainer 120 and is supported by the support members 306.
    FIG. 4 shows a close-up sectional view of the filtration system 100 comprising the filter cartridge 104 inserted in the operating position in the housing. When the filter cartridge 104 is inserted into the housing (comprising the lower shell 102 and the upper shell 402), the actuating finger of the valve 134 extends into the orifice 130 and pushes the ball 128 away from it. the orifice 130, thereby putting the valve 126 in the open position. When the valve 126 is in the open position, filtered fuel can flow into the fuel supply pipe 132. An upper shell 402 of the housing immobilizes the filter cartridge in the operating position. The upper shell 402 is fixed to the lower shell 102 by a corresponding thread 404. A seal 406 may be interposed between the upper shell 402 and the lower shell 102.
    As seen in the sectional close-up view of Figure 5 showing the valve 126 with the filter cartridge 104 inserted into the operating position in the housing, the actuating finger of the valve 134 is inserted into the port 130 and in an opening 502. The tip of the operating finger of the valve 134 has dimensions and a shape for closing the opening 502 hermetically. The passage 302 of the operating finger of the valve 134 opens into the opening 502. opening 502 communicates with the fuel tank supplying the fuel to be filtered to the filtration system 100. The passage 302 in the operating finger of the valve 134 and the opening 502 allows air trapped between the upper shell 402 and the second plug 116 to be pushed back from the housing to the fuel tank. The trapped air may be separated from the fuel during filtration or may be trapped when the upper shell 402 is removed and secured (for example during a maintenance operation of the filter cartridge).
    As described above, the fuel flows into the fuel supply pipe 132 from the housing only when the actuating finger of the valve 134 opens the valve 126. The actuating finger of the valve 134 opens the valve. valve 126 when the strainer device 118 is put into operating position in the housing. As a result, the fuel flows when the strainer device 118 with the actuating finger of the valve 134 is in the installation position. The strainer device 118 may be in the installation position only if the strainer device 118 is installed in the filter cartridge 104 and the filter cartridge 104 is fully installed in the operating position in the housing. In this way, the installation of the actuating finger of the valve 134 on the strainer device 118 ensures the presence of the two filtering parts (the strainer device 118 and the primary filter element 108). This prevents the internal combustion engine and its members, such as fuel injectors, from receiving fuel containing impurities. On the other hand, the multi-piece design of the filter cartridge 104 including the primary filter element 108 and the separable strainer 118 helps to ensure the use of the appropriate parts of the filter cartridge during maintenance operations. If an inappropriate part is used, no fuel can flow between the filtration system 100 and the internal combustion engine, which therefore prevents fuel potentially containing impurities from entering the engine at all. internal combustion.
    On the other hand, the strainer device 118 may have a life time different from that of the primary filter element 108. Since the strainer device 118 is a separate independent accessory, the strainer device 118 and the primary filter element 108 may be replaced separately from each other. For example, if the strainer device 118 is intended to have a longer filter life than that of the primary filter element 108, a user of the internal combustion engine can separately replace the primary filter element 108 with multiple This arrangement reduces the costs of the spares because customers only have to purchase either the strainer 118 or the primary filter element 108, and not both. both as in the arrangements where the strainer device 118 and the primary filter element 108 are one. In addition, such an arrangement reduces unnecessary waste, since the primary filter element 108 and the strainer device 118 can each be replaced separately according to their individual filtering capacity (for example their maximum individual level of fouling).
    FIG. 6 shows a sectional view of a filtration system 600 according to another embodiment. The filtration system 600 comprises a housing composed of a lower case shell 602 and an upper case shell 604. The filtration system 600 includes a filter cartridge 606 removably housed in the housing. The filter cartridge 606 is similar to the filter cartridge 104 of the system 100. The filter cartridge 606 has a substantially cylindrical shape and includes a primary filter element 608 comprising a filter medium (for example a paper-based filter media, a foam filter media, a cotton-based filter media, a pleated filter media, etc.) which filters a liquid such as a fuel. The primary filter element 608 comprises a dirty face 610 and a clean face 612. The dirty face 610 receives the liquid to be filtered and the clean face 612 passes the filtered liquid. A first end of the filter media is secured by a first plug 614 and a second end of the filter medium is secured by a second plug 616. The first plug 614 is open. In some arrangements, the second plug 616 is open. The filter cartridge 606 is housed over a riser 618 when the filter cartridge is in the operating or installation position (as shown in Figure 6). In a manner similar to the filter cartridge 104, the filter cartridge 606 includes a removable strainer device 620. The strainer device 620 comprises a strainer 622. The strainer 622 is a hydrophobic strainer. Strainer 622 intercepts, collects and removes water remaining in the fuel after the fuel has passed through primary filter element 608. Strainer 622 has a substantially cylindrical shape so that it can be inserted over column 618 and within the primary filter element 608. In this way, the strainer 622 is placed on the clean face 612 of the primary filter element 608. The strainer device 620 is placed inside a small opening in the primary filter element 608 and the column 618 is placed in an opening in the strainer device 620 when the filter cartridge 606 is in the operating position. In other words, the primary filter element 608, the strainer device 620 and the column 618 are nested within each other when the filter cartridge 606 is in the operating position.
    The strainer device 620 includes a plug portion 624. Unlike the strainer device 118 of the system 100, the strainer 622 and the plug portion 624 are formed integrally. The strainer device 624 is removably housed in the filter cartridge 606. The plug portion 624 is removably housed in the second plug 616. The assembly of the plug portion 624 with the second plug 616 can be achieved by an interlocking assembly, a snug fit assembly, a friction fit or the like. A seal 626 may be interposed between the plug portion 624 and the second plug 616 to hermetically seal the dirty face 610 from the clean face 612. The plug portion 624 includes an enlarged chamber 628 for collecting air separate.
    Still with reference to Figure 6, the filtration system 600 comprises a valve 630. The valve 630 is a valve blocking the filtration system in the absence of filter element. The valve 630 is placed at one end of the column 618. The valve 630 comprises a ball 632 pushed to a port 634 of the valve 630. The ball 632 has dimensions and a shape for sealing the orifice 634. , the valve 630 is pushed to the closed position (i.e., the ball 632 prevents the fluid from passing through the orifice 634) which prevents the flow of fluid through the valve 630. The orifice 634 opens into a fuel supply pipe 636 which supplies fuel filtered by the filtration system 600 to a member of an internal combustion engine such as a fuel injector. When the valve is in the closed position, it is impossible for fuel to pass from the filter housing to the internal combustion engine. The plug portion 624 comprises an actuating finger of the valve 638. As shown in FIG. 6, when the filter cartridge 606 is fully inserted into the casing and is in an operating position in the casing, the finger of FIG. Actuation of the valve 638 pushes the ball 632 away from the hole 634, thereby causing the valve 630 to open to allow fuel flow into the fuel supply pipe 636. In a similar manner to the filtration system 100, in the filtration system 600, the fuel flows into the fuel supply pipe 636 from the housing only when the actuating finger of the valve 638 sets the valve 630. in open position. The actuating finger of the valve 638 only puts the valve 630 in the open position when the strainer device 620 is placed in operating position in the casing constituted by the upper and lower shells 602 and 604. As a result, the fuel flows when the strainer device 620 provided with the actuating finger of the valve 638 is in the installation position. The strainer device 620 can only be in the installation position if the strainer device 620 is installed in the filter cartridge 606 and the filter cartridge 606 is fully installed in the operating position in the housing. In this way, the installation of the actuating finger of the valve 638 on the strainer device 620 ensures the presence of the two filtering parts (the strainer device 620 and the primary filter element 608). This prevents the internal combustion engine and its members, such as fuel injectors, from receiving fuel containing impurities. On the other hand, the multi-piece design of the filter cartridge 606 including the primary filter element 608 and the separable strainer 620 helps to ensure the use of the appropriate parts of the filter cartridge during maintenance operations. If an inappropriate part is used, there can be no fuel flow between the filtration system 600 and the internal combustion engine, which therefore prevents fuel potentially containing impurities from entering the engine at all. internal combustion.
    On the other hand, the strainer device 620 may have a life time different from that of the primary filter element 608. Since the strainer device 620 is a separate independent accessory, the strainer device 620 and the primary filter element 608 may be replaced independently of each other. For example, if the strainer device 620 is intended to have a longer filter life than that of the primary filter element 608, a user of the internal combustion engine can separately replace the primary filter element 608 with multiple This arrangement reduces the cost of spare parts because customers only have to purchase either the strainer 620 or the primary filter element 608, and not both. both as in the arrangements where the strainer device 620 and the primary filter element 608 are one. In addition, such an arrangement reduces unnecessary waste, since the primary filter element 608 and the strainer device 620 can each be replaced separately according to their individual filtering capacity (for example their maximum individual level of fouling).
    The filter systems and arrangements of filter cartridges described above are presented in the context of fuel filters. However, similar principles can be applied to filtration systems of other liquids. For example, similar filtering systems can be used in lubricant filter systems, hydraulic fluid filtration systems, and the like.
