The device further comprises a first spring retainer (36) attached to an intermediate part of the valve stem (32) to engage a first valve spring (35), and a second spring retainer (44) slidably engaged by an end part of the valve stem to engage a second valve spring (43). The valve stem is provided with a stem end (39) which is enlarged with respect to a part of the valve stem slidably engaging the second spring retainer so as to define a shoulder surface (40a) that engages the second spring retainer against a spring force of the second valve spring.

Abstract: The invention relates to a cup tappet for an internal combustion engine, having a skirt which has a radial recess, into which an anti-rotation element (6) is inserted. The anti-rotation element protrudes from the skirt in the radial direction, in order to be accommodated in a corresponding groove of the cylinder head as an anti-rotation safeguard. According to the invention, the anti-rotation element (6) has an outer contour in longitudinal section with a head (20) and a stem (21). The stem has a reduced dimension compared with the head (20) and a thickened portion (32), and can be clipped into the recess of the skirt of the cup tappet under elastic deformation of the thickened portion (32). In this way, an anti-rotation safeguard is possible which can be assembled particularly simply, can be manufactured cheaply and is reliable.

Abstract: In a tappet (1) of a valve train of an internal combustion engine, the leakage of hydraulic medium occurring between its reception bore (6) and skirt (2) is to be reduced. To achieve this, the tappet (1) of the invention comprises an anti-rotation device (22) and, at the same time, a supply of hydraulic medium from a supply gallery (21) to an annular oil reservoir (17) is effected directly, i.e. annular grooves and other oil deflecting measures are dispensed with. An aperture (19) in the skirt (2) for the supply of hydraulic medium can, at the same time, be advantageously arranged in a bottom-proximate region thereof.

Abstract: A valve tappet actuated by a cam of an internal combustion engine comprises a cup (1) having a hollow cylindrical skirt (2) and a cup bottom (3) which closes the skirt (2) at one end. On an outer surface, the skirt (2) comprises a peripheral groove (4), and on an inner surface, at least one bead (5). Concentrically arranged within the cup (1) is an inner element (6) whose casing (9) bears against the bead (5, 21). A hydraulic valve clearance compensation element (10) is guided for axial displacement in the inner element (6). To simplify the manufacturing of this valve tappet, it is proposed that the cup (1) is hardened in a heat treatment process, and the inner element (5) is unhardened.
