摘要： A valve deactivation device for a rocker arm assembly having a cam arm and a valve arm is provided. A return spring biases a locking latch pin toward an activated position to allow the cam arm and the valve arm to rotate together. The latch pin can be translated against the biasing force of the return spring to decouple the cam arm and valve arm for relative rotation. The latch pin and the latch pin housing are adjusted so as to limit the clearance between them and mate the latch pin and the latch housing. The cam follower and the actuator section of the rocker arm are mounted on, and are not independent of, the rocker shaft. Clearances between parts are controlled such that their relative rotation is strictly limited in the selective engagement of the latch pin in one section and latch pin receiving hole in the other section.

摘要： A hydraulic cam follower for simultaneous actuation of several equal-acting gas-exchange valves, especially for a tappet pushrod valve train of an engine, includes an outer part, whose base forms a cam contacting surface, and from whose head hollow-cylindrical guides extend in the same number as the valves in a direction towards the base. A housing of a hydraulic play compensation element is provided in each guide and sits with its bottom side on an inside of the bottom of the outer part. A concentric pressure piston is guided in a borehole starting from a head end of each housing so it can move axially. A non-return valve is located at a bottom-side base of the piston and a high-pressure space is formed axially between the base and the bottom side of the housing. A reservoir for hydraulic medium is formed between the base and a head end of the piston.

摘要： The low profile valve lifter assembly has flats inside the bore of the outer housing and walls are formed and extended down from the plate of the guide such that the walls align with the flats of the bore to prevent rotation of the lifter with the guide. A groove and protuberance are provided in the flats and on the side wall of the guide in order to properly orient the lifter with the guide. The flats can be connected to form a pocket and the walls of the guide can be connected to form a sleeve that mates with the pocket.

摘要： A valve drive (1) for an internal combustion engine with a lever-type cam follower (7) is provided, which is used for the variable adjustable transmission of a raised section (2) of a cam (3) to a gas-exchange valve (5), in that the cam follower (7) is supported with an end section (13) away from the cam on a pivot bearing (14), which can be positioned variably on a circular arc-shaped displacement path (15), and an end section (6) close to the cam includes a transmission surface (10) in connection with the gas-exchange valve (5), and also with a support (8), wherein a contact surface (9) for the cam (3) is mounted rotatably on this support (8). Here, the center of the displacement path (15) should be essentially identical to the rotational center (17) of the support (8) when the contact surface (9) interacts with a raised section-free base circle (21) of the cam (3).

摘要： The finger follower has an inner and outer body and a torsional lost motion spring positioned at its lash adjuster end of the outer body. The torsional lost motion springs have a short leg that abuts the outer body and a long leg that contacts the inner body. The torsional spring is located above the pivot point of the finger follower so as to provide a low mass moment of inertia and to reduce the weight over the valve stem end of the follower.
