Abstract: According to the present invention, an outer lever (1) of a finger lever (2) that can be switched to different lifts for at least one gas exchange valve is made by a deep drawing method. A salient feature of the invention is that through a special trimming operation of the cup-shaped base body (16) that is formed in a first step of the method, running contact surfaces (14, 15) for cams, preferably high-lift cams, are generated on upper sides (12, 13) of arms (4, 5) of the outer lever (1). Through the deep drawing method of the invention, only relatively low fabrication costs are to be expected.

Abstract: Connecting element (10) retains cam follower (2), which actuates gas-exchange valve (4) of an internal combustion engine, on support element (6). Support element (6) has spherical end (7) on cylindrical section (22) and on which cam follower (2) is mounted, so as to be pivotably movable in the direction of gas-exchange valve (4) about center of rotation (9). Connecting element (10) has elastically deformable projections (21), which proceed from central webs (19), parallel to the pivot axis of cam follower (2) such that connecting element (10) is connected to cylindrical section (22) in a frictionally-engaging manner. Projections (21) are embodied as lugs (20) which angle away from central webs (19) and extend in a direction pointing away from cam follower (2), so that projections (21) are elastic in shape.

Abstract: A corrosion-resistant alloy tube is formed and bonded to a pre-machined steel alloy rod to form a riser tensioner cylinder rod. During assembly, an epoxy is injected into an annular space between the tube and rod and then cured. The bonded tube is ground to a desired surface finish prior to installation and utilizes a double seal arrangement that prevents external pressure or corrosive fluids from entering the cured epoxy in the annular space.

Abstract: The present invention provides a rocker arm manufacturing method capable of stably forming valve stem guide walls. In the method according to the present invention, an intermediate product 13 having both side walls 20 extended in a predetermined direction and arranged in parallel with each other and a one end side connection wall 30 connecting lower ends of both the side walls 20 at a longitudinal one end of the product is obtained. Next, a first pressing punch 70 is pressed against the outer surface portions of both the side walls 20 from the outside thereof to cause downward plastic flows of regions of the outer surface portions of both the side walls positioned below the cutout portions 31 to thereby form raising walls 32 in a downwardly protruded manner at both sides of the one end side connection wall 30. Thereafter, valve stem guide walls 35 are formed by pressing second pressing punches 80 against both the raising walls 32 of the one end side connection wall 30.

Abstract: A valve control mechanism is provided for an overhead valve, internal combustion engine having a camshaft moving a pushrod to move a rocker arm that in turn moves the valve. Three aligned rollers are fastened to the end of the pushrod adjacent the rocker arm. The outer two rollers roll along parallel profiled surfaces that control at least the valve lift and ramp. The middle roller rolls along an engaging surface on the rocker to move the rocker arm in a motion determined by the configuration and location of the profiled surfaces and the engaging first and second rollers. The outer rollers rotate in a direction opposite the middle roller.
