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： 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 spring has two helical parts each with 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.

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 switchable valve train for gas-exchange valves of internal combustion engines with a rocker arm device (1), in which a rocking motion about a rocker arm axis (3) can be introduced by at least one cam (2a, 2b), one tappet, or the like, wherein this rocking motion can be transmitted to at least one valve (4). The rocker arm device (1) is formed from at least one cam lever part (5) in working connection with the cam (2) and a valve lever part (6) in working connection with the valve (4), which are supported so that they can rock about the rocker arm axis (3).

摘要： A hydraulic cam follower (1), such as a roller tappet, is provided. This is used for the actuation of two identically operating gas-exchange valves and should be installed inclined to the direction of the force of gravity. The cam follower (1) comprises a pot-shaped housing (2), whose bottom (3) is provided with a roller as a cam contacting element (4). In the housing (2), two guides (5) extending parallel to the direction of the internal combustion engine are provided, in each of which a pressure piston (6) is arranged so that it can move axially, whose end (7) away from the housing is constructed as a support for contact with a respective tappet pushrod. Each pressure piston (6) encloses a reservoir (11) for hydraulic medium. For each pressure piston (6), an opening (13) extends from the outer casing (12) of the housing (2) for feeding hydraulic medium to the reservoirs (11), wherein the openings (13) are arranged on a peripheral segment of the outer casing (12) lying at the top viewed in the direction of the force of gravity. Thus, a so-called double roller tappet is provided as a cam follower (1), which can store a sufficiently large amount of hydraulic medium despite its inclined installation.
