摘要： A switchable bucket tappet for a valve drive of an internal combustion engine, which has a bucket basic body with a ring-like base. A hollow-cylindrical projection protrudes from an inner edge of the base, and in the bore of the projection an inner body extends. Two coupler pistons lie opposite one another and, to achieve a full valve stroke, engage in sections with a driver surface of the bucket basic body which run in a radial hole of the inner body. A zero valve stroke is achieved when the coupler piston is displaced completely into the radial hole of the inner body, which is baseless and free of contact with a cam. The projection has a window-like aperture, with the underside acting as the driver surface for an upper side of the coupler piston during coupling. The region of the base is an approximately symmetrical and continuously thin-walled formation.

摘要： A force transmitting device (4) for a valve drive (1) of an internal combustion engine (2) with a hydraulic valve lash compensating device (6) is provided. The force transmitting device (4) has a hollow cylindrical compensating piston (13), which on one end defines a working chamber (35) of the valve lash compensating device (6) and on the other end encloses an internal hydraulic medium reservoir (15) used to supply the working chamber (35). This is connected to a hydraulic medium supply (16) of the internal combustion engine (2) and is protected from a return flow of hydraulic medium in the direction of the hydraulic medium supply (16) by means of a valve plate (26), which can be pressurized and which can move axially, in that the valve plate (26) interacts in a sealing way with an axial annular surface (28) of the compensating piston (13) for a non-pressurized hydraulic medium supply (16). Here, the valve plate (26) should have one or more openings (34), which connect the internal hydraulic medium reservoir (15) to an external hydraulic medium reservoir (31) for a non-pressurized hydraulic medium supply (16).
