Abstract: A cam phaser (10) dynamically adjusts a rotational relationship of a camshaft (24) of an internal combustion engine with respect to an engine crankshaft (34). A cam sprocket (20) can be driven by an endless loop power transmission member connected to a drive sprocket (36) mounted for rotation with the engine 5 crankshaft (34). The cam phaser (10) can include a planetary gear drive train (12) having a centrally located sun gear (14) connected for rotation with the cam sprocket (20), a ring gear (18) connected for rotation with the camshaft (24), and a plurality of planet gears (16a, 16b) supported by a carrier (22) in meshing engagement between the sun gear (14) and the ring gear (18). A phase adjustment gear (26) can be 10 connected for rotation with the carrier (22). The sun gear (14) can drive the planet gears (16a, 16b) in rotation thereby causing the ring gear (18) to be driven in rotation. Rotational movement the phase adjustment gear (26) can adjustably vary a cam phase position of the camshaft (24) relative to the crankshaft (34).

Abstract: The finger follower employs two independent lost motion arms and a rod which moves longitudinally to lock both arms. The rod is transversely mounted in the follower. In order to avoid premature locking, each arm has a chamfered surface on a top wall to force the rod out of engagement with the arm during upward movement of the arms, to protect premature movement of the rod from an unlocked position to a locked position.

Abstract: A corrosion-resistant alloy tube is formed and bonded to a pre-machined steel alloy rod to form a riser tensional 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: 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 a cup-shaped base body (16) having an inverse U-shaped cross-section is deep drawn, and opposing running contact surfaces (14, 15) for high-lift cams are created on arms (4, 5) of the outer lever (1) by punching out a bottom (19) of the base body (16). Through the deep drawing method of the invention, only relatively low fabrication costs are to be expected.

Abstract: An internal combustion engine having a plurality of intake and/or exhaust valves associated with each cylinder includes a valvetrain having a fulcrum with a plurality of pivot ball sockets each associated with a rocker arm and pivot ball disposed between the fulcrum and the rocker arm with the fulcrum extending through apertures of the rocker arms and having a plurality of slots, each slot having generally parallel opposing lateral surfaces for receiving and guiding both sides of an associated rocker arm so the rocker arm pivots about the pivot ball in a plane of the rocker arm. The fulcrum can accommodate at least two rocker arms that may operate in non-parallel planes relative to one another and can include bearing and locating surfaces integrally formed to finish dimensions to eliminate machining.

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: A riser tensioner cylinder rod incorporates a thin, corrosion-resistant alloy tube over a pre-machined steel alloy rod. The tube is swedged at one end and expanded to the inner surface of a split die. A gradual tapered surface on a stretching die provides a smooth transition during a stretching process for the tube. A pressurizing vessel traps an outer lip of the pre-swedged tube. Pressurized fluid in the vessel simultaneously causes the tube to expand and force the rod into the tube inner diameter. At the completion of the process, the pressurizing vessel is removed. The stretched tube is parted off at both ends and the stretching die is removed from the rod to complete the assembly.
