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 switchable cup tappet for a valve timing mechanism of an internal combustion engine, which has a cup basic body with an annular base loaded by large-lift cams. A hollow-cylindrical projection protrudes from an inner edge of the base and an inner body extends in the hole of the projection. The disc-like base is contacted by a small-lift cam. In a hole of the inner body two coupler pistons are coupled in sections with a driver surface of the cup basic body for a large valve stroke. The small stroke occurs by complete displacement into the radial hole. An annular web, spaced from its end faces at both ends, is attached integrally, in which the radial hole extends with the coupler pistons. The driver surface for the pistons is formed by a lower edge of the projection, which is spaced from the bases.

摘要： A switchable cam follower (1) of a valve train of an internal combustion engine is proposed, having an inner lever and an outer lever (2, 3), wherein the levers (2, 3) can be connected to one another via coupling means (12) and run on a common pin (15) such that they can be moved pivotably relative to one another, which pin (15) is projected around by at least one group of turns (16) of a swivel pin spring (17) as cam restoring spring, wherein a first limb (19) which protrudes from an end side (18) of the group of turns (16) acts on a first clamping point (20) of the outer lever (3) and a second limb (22) which protrudes from another end side (21) of the group of turns (16) acts on a second clamping point (23) of the inner lever (2), in the rotational direction in such a way that the levers (2, 3) are present such that they are stressed towards one another, wherein the pin (15) runs in a “floating” manner with respect to the holes (13, 14), wherein the group of turns (16) comprises a bush (24) with play, wherein axial fixing of the pin (15) is produced via the offset contact of the group of turns (16) on the bush (24), which offset contact is brought about by the system stressing, and therefore the offset contact of said bush (24) on the pin (13), and wherein, in order to reduce a resulting contact force (FR) in the region of the contact of the group of turns (16) on the bush (24), the clamping points (20, 23) of the two limbs (19, 22) of the group of turns (16) are positioned in such a way that an angle (α) which is enclosed by intersecting force vectors at the clamping points (20, 23) [direction of action of the two contact forces (F1, F2)] lies in the range (90°

摘要： A cam follower (1) designed to be switchable between different lifts for at least one gas-exchange valve and includes two adjacent sections (2,4) which can be coupled together via a coupling element (15). The coupling element (15) cooperates with a shutoff slide (14). It is a special feature of the shut-off slide (14) that it is produced as a mechanically closable and openable piston for an inlet (22) in a pressure chamber (20) in front of the coupling means (15), the piston, however, being maintainable hydraulically in its open position via high switching pressure. At the same time, the shutoff slide (14) is completely incorporated in the cam follower (1) and does not extend beyond it. As a result, undesired fluctuations in the pressure of the hydraulic fluid can no longer act on the coupling means (15) during the base circle of the cams acting on the cam follower (1) and an intended turned-off state. At the same time, displacement of these coupling means (15) in their coupling direction is only possible if a sufficiently high pressure of the hydraulic fluid is available for such movement. Otherwise, the shutoff means (14), via the force of a pressing means (10), will close the inlet (22) for hydraulic fluid.
