摘要： What is proposed is a lever-type cam follower (1) made of sheet metal, typically for a valve train of an internal combustion engine, said cam follower (1) comprising two parallel side walls (3a, 3b) connected by a crossbeam (2), an underside (4) of the crossbeam (2) having a support (6) for at least one gas exchange valve on one end (5), said support (6) being limited by guide walls (7a, 7b) extending parallel to the side walls (3a, 3b), wherein the one end (5) of the cam follower (1) is narrower than the rest of the length of the cam follower (1), and at least in the region of said one end (5), the side walls (3a, 3b) have a smaller mean wall thickness (DSM) than over the rest of said length, which wall thickness (DSM) increases at least in said region continuously from ends (8a, 8b) of the side walls (3a, 3b) in the direction of the crossbeam (2), and the thickness (DF) of the guide walls (7a 7b) is smaller than the mean wall thickness (DSM) in the region of the narrow one end (5). Such a cam follower (1) requires only a small design space in the region of the one end (5) and has a particularly favorable mass moment of inertia.

摘要： A mechanical valve tappet for timing the valves of an internal combustion engine comprising a cup-shaped housing (1), consisting of a hollow cylindrical wall (2) closed at one end by a bottom (3) which is exteriorly contacted by a control cam (6), while on the inner surface of the bottom (3), there is arranged an elevation (4) which cooperates with the end of a valve stem of a gas exchange valve (5) and while the other dimensions of the valve tappet remain unchanged, the elevation is made in each case with a different axial extent whereby the valve clearance can be adjusted without the adjusting elements hitherto required by the prior art by inserting the entire cup-shaped housing (1) having the appropriate elevation (4) into the cylinder head.
