    Field
    [0001] The present teachings are directed to pump actuators and more specifically to anti-rotation devices for tappets such as fuel pump actuators. Background
    [0002] Tappets, such as fuel pump actuators, provide a mechanism for translating the rotational movement of a rotating mechanism such as a cam in linear motion. The relatively efficient translation of energy from rotational motion from rotary mechanism to linear movement of the tappet typically requires specific alignment of the tappet with respect to the rotary mechanism. summary
    [0003] The present teachings generally include a pump actuator tappet having a contiguous body including an outer wall and a transverse web. The outer wall defines a cylindrically shaped outer surface and a recess. The recess is disposed within the cylindrical surface of the body. An alignment member is snapped between two stacked ends of the recess, which contact opposite sides of the alignment member. When in place, the alignment member extends outwardly from the cylindrically shaped surface. A roller is mounted on the contiguous body at the cam contact end of the tappet.
    [0004] In a further aspect of the present teachings, a tucho has a contiguous body having a first end, a second end and an outer wall defining a first cylindrically shaped outer surface. The contiguous body also defines an alignment portion that extends radially outwardly from the first outer surface. The alignment portion has a cylindrically shaped wall that is aligned with the direction of travel of the roller tapp. Brief description of the drawings

    [0021] Figures 1 and 2 illustrate perspective views of a tucho 100 according to the many aspects of the present teachings. Tucho 100 can have a first end 102 and a second end 104. A body 106 of tucho 100 can define an outer wall 105 having a cylindrical outer surface 108. The cylindrical outer surface 108 can be centered on a central geometric axis A (figures 1, 2, 4, 12 and 13). As used here, the terms "longitude", "longitudinal" or similar terms can refer to a direction parallel to A. The terms "radial", "radially" or similar terms can refer to a direction along a perpendicular line to the geometric axis A. The terms "outward", "outward" or similar terms can refer to directions away from the geometric axis A, while the terms "inward" or "inward" can refer to directions in the direction of the geometric axis A. Since the relative directional terms "internal" and "external" are used here, an "internal" element can be spaced closer to the central geometric axis A than the "external" element.
    [0022] A roller 110 can be mounted on a body 106 at a first end 102 through an axis 112 that can seat within shaft holes 114. During operation, the first end 102 of the tappet 100 can make contact with a cam rotary 206, for example as shown in figure 5, which can cause the tappet 100 to periodically move along the longitudinal direction. The tappet 100 can take other shapes at the first end of cam contact 102. For example, instead of a roller 110, tappet 100 can be constructed with a cam contact surface like that of a tappet without a roller. A web 116 may extend transversely with respect to geometry axis A, and may form part of a roller cavity 118.
    [0023] An alignment member 120 can fit under pressure within a recess 122. Alignment member 120 can be a cylindrical pin that can extend outwardly from cylindrical outer surface 108. Alignment member 120 can be fixed between two stacked portions 124 of body 106. These stacked portions 124 can form alignment member fixing surfaces 130, 132 that can project into recess 122 and that can hold alignment member 120 in place. The grooves forming the stacked portions 124 can be formed in the body 106 before or after insertion of the alignment member 120 into the recess 122.
    [0024] With reference to figure 3, the tucho 100 includes roller bearings 111 on which roller 110 can be mounted on shaft 112 and body 106. When mounted, roller bearings 111 can be positioned in roller cavity 118 and can encircle shaft 112 to allow low friction rotation of roller 110 over shaft 112. Axle 112 can be inserted through shaft holes 114 and a subset including roller 110 and shaft bearings 111 while such a subset is positioned in cavity 118.
    [0025] With reference to figure 4, the alignment member 120 can have a cylindrical shape that can be defined by a surface 140. A first end 142 and a second end 144 of alignment member 120 can be substantially flat and can be oriented perpendicular to the geometric axis B, which is the central geometric axis of the cylindrical alignment member 120. Both ends 140, 144 can be circular in shape. When assembled, alignment member 120 can be snapped into a recess 122 between alignment member attachment surfaces 130, 132. As further described in connection with figure 8, alignment member attachment surfaces 130 , 132 can have protrusions that can extend into recess 122. Recess 122 can be formed in body 106 adjacent to alignment member attachment surfaces 130, 132. In one example, recess 122 can be formed by stacking the body 106. Once assembled, alignment member 120 can extend outwardly from cylindrical surface 108 of tucho 100 and interrupt its cylindrical outer contour. It will be appreciated in light of the disclosure that the tappets according to the present teachings include ornamental features in addition to and in addition to the functional aspects described here.
    [0026] In one aspect of the present teachings, the body 106 of the tucho 100 can be formed from a contiguous piece of material (that is, a single piece of material) and is manufactured by a forming process, such as forming a cold. In another aspect of the present teachings, the body 106 can be a contiguous piece of metal produced from an initial material of forging material which can be formed and subsequently heat treated or machined or both. Examples of such forging metals may include but are not limited to grade 1522, grade 1018, grade 1018, grade 1008-1010, grade 8124 and grade 5120 steel.
    [0027] With reference to figure 5, the tappet 100 can be included with a fuel pump housing 200. The outer cylindrical surface 108 of the tappet 100 can be configured to interface with a guide hole 201 of a fuel pump housing 200 The guide hole 201 can have a complementary cylindrical shape in relation to the outer cylindrical surface 108. The alignment member 120 can run in a slot 202. The slot 202 can be sized to allow only relatively small amounts of rotational movement of the tappet over its longitudinal geometric axis A in relation to its longitudinal movement. Rotating a cam 206 can cause the tappet 100 to transfer linear motion to a piston 208.
    [0028] As shown in figures 6 and 7, a concave curved surface 148 can partially surround the recess 122. The concave curved surface 148 can prevent any sharp corners from forming between the cylindrical outer surface 108 and the recess 122. The existence of sharp corners can be demonstrated to possibly interfere with the correct operation of the tucho 100. The concave curved surface 148 can also be shown to aid in the formation of the stacked portions 124 of the body 106 by removing additional material adjacent to the stacked portions 124 that otherwise could be distorted during the process used to form the stacked portions 14. Removing such materials prevents material from extending outwardly from the cylindrical surface 108 and potentially obstructing the movement of the tappet 100.
    [0029] With reference to figure 8, a body 106 of a tucho 100 has a cylindrical surface 108 which can define a recess 122 disposed within the cylindrical surface 108 of the body 106 of a tucho 100. The recess 122 can have an embedded surface 150 which may include a first curved surface 152, a second curved surface 154, and an intermediate surface 156. In one aspect of the present teachings, each of the curved surfaces 152, 154 and intermediate surface 156 may have cylindrically shaped surfaces, the central geometric axes of which they can be parallel to the geometric axis A, coinciding with the direction of travel of the tappet 100. A first aligning member fixing surface 130 can be arranged at the end of the recess 122 proximal to a cam contact end 102 of the tappet 100 , while the second alignment member fixing surface 132 is arranged at the end of the recess 122 distal from the contact end of cam 102 of tucho 100. Alignment member attachment surfaces 130, 132 can be configured to receive a cylindrical alignment member 120. In one example, alignment member attachment surfaces 130, 132 can be configured to receive alignment member 130 cylindrical alignment member 120, as shown in figure 4. One or both of the alignment member fixing surfaces 130, 132 may have a projecting surface 158 that can extend into recess 122. The projecting surfaces 158 are a result of stacking process that can form stacked portions 124. Stacked portions 124 can therefore be adjacent to alignment member attachment surfaces 130, 132 and in particular adjacent to protruding surfaces 158. alignment member attachment surfaces 130, 132 they can contact the ends of an alignment member 120 in a snap fit relationship and thus they can fix the alignment member 120 in recess 122. In this arrangement, the concave curved surface 148 may partially surround recess 122.
    [0030] With reference to figure 9, the alignment member 120 can be in the form of a cylindrical pin having radius R (shown with dashed lines). In one aspect of the present teachings, more than half the volume of the alignment member 120 can be disposed within the recess 122, and in particular, more than half of the volume of the alignment member 120 can be disposed radially inwardly with respect to the outer surface. cylindrical 108. The recess surface 150 can be formed from three cylindrical curved surfaces: a first alignment member contact surface 152, a second alignment member contact surface 154, and an intermediate surface 156. The surfaces of alignment member 154 alignment member contact 152, 154 may be cylindrical in shape with central geometrical axes aligned with geometry axis A. The radius of both alignment member contact surfaces 152, 154 may be greater than the radius R of the alignment member cylindrical 120. Alignment member contact surfaces 152, 154 may also cooperate to limit the depth at which the alignment member line 120 can be inserted. For example, alignment member 120 can make contact with one or both of the contact surfaces of alignment member 152, 154 as alignment member 120 is inserted during manufacture, or during operation when the alignment member 120 can encounter contact forces with an internal surface of a fuel pump housing 200. Alignment member contact surfaces 152, 154 can prevent alignment member 120 from further retracting into recess 122 providing support for the member alignment 120 when in contact with alignment member 120. The support for alignment member 120 can be shown to be from a perpendicular force applied to alignment member 120 at the point of contact between alignment member 120 and a or both of the alignment member contact surfaces 152, 154. The perpendicular force applied by either of the alignment member contact surfaces line 152, 154 can be oriented to a point at an oblique angle to the radial direction p at the point or points of contact between alignment member 120 and member contact surfaces 152, 154.
    [0031] The intermediate surface 156 can join the contact surfaces of alignment member 152, 154. In one aspect of the present teachings, the intermediate surface 156 is a cylindrical surface with a geometric axis aligned with the geometric axis A. The radius of curvature of the intermediate surface 156 may be less than the radius R of the alignment member 120. In alternative aspects of the present teachings, the intermediate surface 156 may have a radius of curvature equal to or less than the radius of curvature of the cylindrical alignment member 120. The intermediate surface 156 does not need to be cylindrical, but can be implemented with other curved or angular shapes including flat and curved surfaces. In another aspect of the present teachings, the intermediate surface 156 does not contact the alignment member 120.
    [0032] Figure 10 illustrates a free-body diagram of alignment member 120. Vectors N1 and N2 represent the directions from which curved surfaces 152, 154 of the recessed surface 150 can apply force to alignment member 120 The forces along the vectors N1 and N2 are contact forces applied by the curved surfaces 152, 154 at their points of contact with the alignment member 120 and are normal to the surface 140 of the alignment member 120. These normal vectors N1 and N2 are oblique with respect to the radial direction p. F1 and F2 represent examples of directions in which forces can be applied against the alignment member 120 by the fuel pump housing 200 and in particular the slot 202 shown in figure 5. During operation inside such a pump housing 200, external forces they can be applied to the alignment member 120 along any vector within the theta band, which covers the angular region between the radius OC and the radius OC '. This angular range corresponds to the range of locations on the alignment member surface 140 that can come into contact with the pump housing 200.
    [0033] In an example where a force is applied to the alignment member surface 140 along the F1 vector, which is in the opposite direction to the perpendicular vector N1, and the force along F2 is zero, the curved surface 154 can apply a sufficient perpendicular force along N1 to cancel the force along F1. Under such circumstances, no outwardly directed force is applied to alignment member 120, and in particular, no force is applied to alignment member 120 tending to dissociate alignment member 120 from recess 122. In another example where no force is applied along the F1 vector, and a force is applied to the alignment member surface 140 along the F2 vector, which is more aligned with the radial direction p than the F1 vector, the curved surfaces 152, 154 can collectively apply forces to the directions N1 and N2 sufficient to cancel the force in direction F2 on the alignment member surface 140, resulting in no net outward force on alignment member 120, and in particular, no force is applied to alignment member 120 in this example tending to dissociate the alignment member 120 from the recess 122. In one aspect of the present teachings, the force applied to the alignment member surface 140 at any point within that of the intermediate 90% of range θ results in no outwardly directed force on alignment member 120 tending to dissociate alignment member 120 from recess 122. In another aspect of the present teachings, the force applied to the alignment member surface 140 at any point within the range θ results in no outwardly directed force on alignment member 120 tending to dissociate alignment member 120 from recess 122.
    [0034] With reference to figure 11, the alignment member fixing surfaces 130, 132 can be arranged at opposite longitudinal ends of the recess 122, with the first alignment member fixation surface 130 arranged close to the cam contact end 102 of the tappet 100, and the second alignment member attachment surface 132 disposed distal to the cam contact end 102. The projecting surfaces 158 that form part of both alignment member attachment surfaces 130, 132 can be formed within of the recess 122 and adjacent to the stacked portions 124 of the body 106. In a further aspect of the present teachings, the stacked portions of the body 106 do not extend beyond the outer cylindrical surface 108.
    [0035] With continued reference to figure 11, a roller cavity 118 can be formed, in part, by a transverse web 116, which can separate the cavity 118 from the cup-shaped portion 160. In one aspect of the present teachings, the cup-shaped portion 160 can receive an end of a piston 208. In another aspect of the present teachings, the recess 122 can be displaced longitudinally from both the cam contact end 102 and the transverse web 116, and can be located between the cam contact end 102 and the transverse web 116.
    [0036] With reference to figure 12, a body 301 can form a first cylindrical outer surface 302 located on an outer wall 303. In one aspect of the present teachings, body 301 can be formed from a contiguous piece of usable forging material in a cold forming process. An alignment portion 320 can have a cylindrical surface 321. The end surfaces 330, 332 can join the cylindrical surfaces 321 of the alignment portion 320 to the first cylindrical outer surface 302 of the outer wall 303. The cylindrical shape of the alignment portion 320 can be centered on a geometric axis parallel to geometric axis A. The body 301 can also have a second 340 and third 342 cylindrical outer surfaces, each having a radius greater than the first cylindrical outer surface 302. The alignment portion 320 of the body 301 can protrude outwardly from the first cylindrical outer surface 302, and may extend radially further than the second 340 and third 342 cylindrical outer surfaces.
    [0037] With reference to figure 13, the alignment portion 320 can be formed as part of the body 301. Both end surfaces 330, 332 can extend from the first cylindrical outer surface 302 perpendicularly to the longitudinal geometric axis of the tucho 300 in opposite ends of the alignment portion 320. The first end surface 330 can be disposed close to the cam contact end 102 of the tappet 300, while the second end surface 332 can be disposed distal to the cam contact end 102. The transverse web 116 it can separate roller cavity 118 from cup-shaped portion 160. Alignment portion 320 is displaced longitudinally from both the cam contact end 102 and the cross web 116, and is located between the cam contact end 102 and transverse web 116.
    [0038] With reference to figure 14, a method of manufacturing 500 of a roller tappet 100 in accordance with the present teachings includes a step 502 of cold forming of a blank ["raw material"] of tappet body. The blank formed in step 502 is then machined in step 504. One aspect of machining step 504 can be machining the ends 102, 104 of the blank to final dimensions, or shaft holes 114. Additional features can be machined, including any aspects of the blank that were not conformed to the final dimensions during forming step 502. In step 506, a recess 122 is formed within the body 106. In one aspect of the present teachings, the recess 122 formed in step 506 may include the surfaces of alignment member contact 152, 154 and the intermediate surface 156.
    [0039] With continued reference to figure 14, alignment member 120 can be inserted into recess 122 and stacked during step 508. Such stacking may include deforming body 106 adjacent to alignment member attachment surfaces 130, 132 in opposite longitudinal ends of the recess 122. Heat treatment step 510 may follow step 508 of stacking alignment member 120. Such heat treatment may include heat treating a subset including body 106 and alignment member 120. In alternative aspects of In the present teachings, heat treatment step 510 can be performed before step 508 of stacking the alignment member. In still other aspects of the present teachings, the deformation of the body 106 adjacent to the alignment member fixing surfaces 130, 132 can be performed before insertion of the alignment member 120 into the recess 122, after which the alignment member 120 can be inserted into recess 122 in a snap fit relationship. Roller 110 is mounted to the bearing in step 512.
    [0040] For the purposes of this disclosure and unless otherwise specified, "one" or "one" means "one or more" ". To the extent that the term "includes" or "including" is used in the specification or claims, it is intended to be inclusive in a similar way to the term "comprising" how that term is interpreted when used as a transitional word in a claim. Additionally, to the extent that the term “or” is used (eg, A or B) it is intended to mean “A or B or both”. When depositors intend to indicate “only A or B but not both” then the term “only A or B but not both” will be used. Therefore, the use of the term “or” here is inclusive, not exclusive. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2nd Ed. 1995). Also, to the extent that the terms "in" or "in" are used in the specification or claims, it is intended to additionally mean "in" or "about". As used here, "about" will be understood by persons skilled in the art and will vary to some extent depending on the context in which it is used.
    [0041] Although the present disclosure illustrates various aspects of the present teachings, and although these aspects have been described in some detail, it is not the intention of the depositor to restrict or in any way limit the scope of the claimed invention to such details. Additional advantages and modifications will be apparent to those skilled in the art. Therefore, the teachings, in their broadest aspects, are not limited to the specific details and illustrative examples shown and described. Consequently, deviations can be produced from such details without deviating from the spirit or scope of the invention claimed by the depositor. In addition, the foregoing aspects of the present teachings are illustrative, and no single feature or element is essential for all possible combinations that can be claimed in this application or in a later one.
