Abstract: The invention concerns a valve tappet which is actuated by the cam of an internal combustion engine and comprises a cup (1) having a hollow cylindrical shell (2) and a base (3) which closes the end of the shell (2). On the exterior, the shell (2) has a peripheral groove (4) and, on the interior, it is provided with at least one bead (5, 21). Disposed concentrically inside the cup (1) is an inner part (6) of which the casing (9) abuts the bead (5, 21). A hydraulic valve clearance compensating element (10) is guided in an axially movable manner inside the inner part (6). In order to facilitate the production of this valve tappet, the cup (1) is hardened in a heat-treatment process and the inner part (6) is unhardened.

Abstract: Upper and lower lift plates (5, 6) are used in a mechanical cup pushrod (1) to set the valve clearance. Here, the lower lift plates (6) have a substantially greater clearance adjustment range HSW than the upper lift plates (5). It is thus possible to reduce the total mass of the cup pushrod (1) further, because, when the cup pushrod (1) is first fitted, the valve clearance is set via the relatively small lower lift plate (6), hence with relatively low mass fluctuations.

Abstract: A pushrod for operating the valve gear mechanism of an internal combustion engine has a cup-shaped housing (1) and an insert formed inside the housing (1) by an outer sleeve (4) bearing on the cylinder wall (2) of the housing (1) and an inner guide tube (5). A hydraulic clearance compensator (7) is movably arranged in the guide tube (5) and the insert forms with the cylinder wall (2) of the housing (1) an oil channel (19) distant from the bottom (3) running from an inlet (18) in the cylinder wall (2) to an opening (20) close to the bottom (3) and adjacent to an oil chamber (13, 15). According to the invention, the oil channel (19) on the insert takes the form of a helical groove in the outer sleeve (4). If the pushrod is secured against rotation inside a cylinder head drilling and is arranged with an inclined longitudinal axis in such a way that the opening (20) is always at the highest point, hydraulic fluid cannot flow from the oil chamber (13, 15) into the oil channel (19) and thus cannot flow out of the oil chamber (13, 15) with the engine stopped.

Abstract: In a pushrod (1) of a valve gear mechanism of an internal combustion engine, the leakage of hydraulic fluid between its locating bore (6) and its shroud (2) is to be reduced. According to the invention, to this end the pushrod (1) has a device (22) preventing its rotation, while at the same time a direct line is provided for taking the hydraulic fluid directly from a supply manifold (21) to an annular oil storage chamber (17), i.e. without recourse to annular grooves or other oil deflectors. Advantageously, there may also be an aperture (19) in the shroud (2) to conduct the hydraulic fluid into a base region therof.

Abstract: A cam follower for the valve gear of an internal combustion engine has a roller (7) fitted on a shaft (5) via roller bearings (6) and contacted by a cam (8). To prevent edge bearing, according to the invention the inner track (11) of the roller (7) is convex in longitudinal cross-section so that the point of greatest load (12) is shifted to the uncritical region for the cam follower between the roller (7) and roller bearings (6). This provides a linear contact between the roller (7) and the cam (8).

Abstract: A cam follower (1) consists of an annular and a circular base section (2, 3). Both base sections (2, 3) are arranged concentrically to each other. A small cam (4) is allocated to the circular base section (3) and at least one larger cam (5) is allocated to the annular base section (2). The two cams (4, 5) are mutually phase-shifted in the circumferential direction. With a cam follower (1) coupled to the large cam (5), the small cam (4) with its projecting lift would undesirably actuate the cam follower (1). Thus, there are means for compensating for said undesirable lift in the cam follower (1).
