Abstract: A roller hydraulic valve lifter or similar cam follower mechanism wherein the follower of such an assembly or mechanism is provided with a pair of spaced apart struts to receive the opposed free ends of a roller shaft carrying a cam follower roller. Each free end of the roller shaft is provided with opposed flats parallel to the axis of the shaft to define abutment shoulders which engage the struts to limit axial movement of the roller shaft in the follower. Each strut is provided at its free end with a tang that is bent over to partly encircle a free end of the roller shaft whereby to retain the cam follower roller and roller shaft in unit assembly with the follower.

Abstract: A rocker arm includes an outer arm defining a stop aperture with a stop surface; an inner arm which selectively pivots relative to the outer arm; a latching mechanism which switches the rocker arm between a coupled state in which the inner arm is prevented from pivoting relative to the outer arm in a first direction and a decoupled state in which the inner arm pivots relative to the outer arm; a lost motion spring which biases the inner arm to pivot relative to the outer arm in a second direction which is opposite from the first direction; and a stop pin fixed to the inner arm and extending into the stop aperture such that the stop pin is circumferentially surrounded by the stop surface and such that the stop pin within the stop aperture limits the extent to which the inner arm pivots relative to the outer arm.

Abstract: A lifter includes a roller caused to abut against a cam thereby to be pressed and a lifter body rotatably supporting the roller and housed in a guide hole of a lifter guide so as to be reciprocable in the guide hole. The lifter body includes a cylindrical part and a rotation stopper. The cylindrical part has an outer periphery formed into a cylindrical shape such that the outer periphery is slidable on an inner periphery of the guide hole. The cylindrical part has one of two axial ends, the one end being formed with a skirt covering the roller. The rotation stopper is formed to protrude outward from the other axial end of the cylindrical part, the other axial end being located opposite a side where the skirt is located. The rotation stopper prevents the lifter body from being rotated about an axis thereof relative to the lifter guide.

Abstract: A high-pressure oil pump roller tappet, used for automobile fuel injection system, mounted between the driving cam and the tappet. The roller tappet includes a shell, a holder, a roller, and a pin. Planes A are arranged on both sides of the seam on lateral sides of the shell. Holes I are arranged at symmetrical positions on two planes A. Holes II are arranged on symmetrical positions on vertical plates. The roller is located in the middle of the pin. Welding has no requirement on the thickness of the plate. The weight can be controlled effectively, reducing inertia force, friction, and wear, improving engine efficiency. The shell and holder are designed as being separate, ensuring that the shell subjects to lateral force as little as possible when the holder subjects to a force, such that the shell is less likely to vibrate. Thus, the shell avoids the abrasion.

Abstract: An assembly for a valvetrain having a valve, a lash adjuster, and a lobe. The assembly includes a shaft, a bearing supported by the shaft for engaging the lobe, and a rocker having a pad for the valve and a socket for the lash adjuster. Walls are disposed between the pad and socket, have inner and outer wall surfaces, and define a valley for the shaft. Upwardly-opening arc-shaped bearing surfaces are disposed longitudinally between the pad and socket spaced laterally from each other and support the shaft when the bearing engages the lobe. A retention element formed in each wall with a depressed portion spaced from the outer wall surface and a lip portion arranged under the depressed portion extends into the valley above the bearing surfaces such that the shaft is prevented from moving out of the valley in absence of engagement between the bearing and the lobe.

Abstract: A roller lifter for internal combustion engines is provided, which has higher rigidity of the lifter body, prevents cocking in the cylinder, and can achieve a size reduction. The roller lifter includes a cylindrical lifter body having a sliding surface on an outer circumferential surface thereof and a roller rotatably attached to the lifter body via an axial support pin and making contact with a rotating cam lobe. The lifter body includes a pair of support portions supporting the axial support pin. The axial support pin is mechanically fastened to the pair of support portions, with both ends thereof inserted in support holes formed in the support portions. The lifter body includes an anti-rotation retainer extending radially outward from the sliding surface. The sliding surface is formed on both front and rear sides in the sliding direction of the anti-rotation retainer.
