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). A coupling device is constructed between the cam lever part (5) and the valve lever part (6), in order to selectively engage and disengage the transmission of the rocking motion.

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 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.
