Abstract (en)
[origin: DE4428309A1] A valve bucket tappet (1) essentially comprises an end wall (7), on which a cam (4) of a camshaft (5) touches, and a cylindrical skirt (6), by means of which the valve tappet (1) is guided in a bore (2) of a cylinder head (3). In order to reduce the valve actuating forces and consequently also to save fuel, it is proposed that the valve tappet (1) be designed with reduced weight. According to the invention the valve tappet (1) is manufactured from a steel material, wall thicknesses A and B of the end wall (7) and the skirt (6) being dimensioned so that a product formed therefrom is P1 </= 2.3. <IMAGE>
