摘要： The invention relates to a mechanical valve play compensation element for a valve drive on a piston combustion engine, comprising a first pressure part (1) which is axially displaceable in relation to a second pressure part (2) and which is fixed in such a way that it can turn about the axis of displacement; a torsion spring element (10) which acts between the first pressure part (1) and the second pressure part (2) and is axially flexible at least to a certain extent; and at least one helical surface (9.1) on the first pressure part (1), to which a corresponding helical surface (9.2) on the second pressure part (2) is allocated, these forming a pair of helical surfaces (9). The surfaces of the helical surface pair (9) are configured as a rough surface and are pressed against each other by the torsion spring element (10).

摘要： The aim of the invention is to functionally improve a hydraulic play compensation element for a valve gear of an internal combustion engine. To this end, the play compensation element is characterized by the following features. Both components (4; 6) enclose a pressure chamber (7) between them, which is sealed from the exterior and which has a volume that depends on the relative position of both components (4; 6). A pressure spring (5) that presses both components (4; 6) away from one another is mounted inside the pressure chamber (7). The pressure chamber (7) can be connected to the storage chamber (8) via a spring-loaded one-way valve (10) through which media can flow exclusively into the pressure space. An additional controllable stop valve (11) is provided in the connection of the pressure chamber (7) to the storage chamber (8). A throttling channel (17), which serves as a bypass to the one-way valve (10), is provided between the pressure chamber (7) and the controllable stop valve (11). The throttling channel (17) is connected to a reversibly size-changing buffer chamber (22).

摘要： A connection between a shaft end of a gas exchange valve of an internal combustion engine and a final control element of a valve actuator, with at least two shell-shaped wedge-shaped pieces, surrounding the shaft end and braced on the final control element, whose radially outer circumferential surface extends conically and which are surrounded by at least one conical clamping sleeve whose radially inner circumferential surface extends complimentary to the cone angle of the wedge-shaped pieces, wherein on the radially inner circumferential surface of the wedge-shaped pieces and on the radially outer circumferential surface of the shaft end of the gas exchange valve, protrusions and recesses that mesh with one another are provided. To enable rotary motions of the shaft end relative to the wedge-shaped pieces, the latter adjoin one another without gaps in the circumferential direction, forming an encompassing wedge-shaped sleeve, whose inside diameter is slightly larger than the outside diameter of the shaft end of the gas exchange valve, and that the protrusions and recesses mesh with one another with slight play.

摘要： The cup tappet (1) of the invention for a valve train of an internal combustion engine comprises a hollow cylindrical skirt (2) whose one end (3) is connected to a bottom (5) for making contact with a cam. The skirt (2) has a clearly smaller height than the overall height of the cup tappet (1), and the bottom (5) rises in a roof-like taper from said end (3). By virtue of this configuration, the bottom (5) has a very high rigidity, so that it is possible to minimize its thickness ‘d’ significantly compared to thicknesses of prior art cup tappet bottoms.

摘要： A hydraulic lash adjuster has a plunger assembly the outer end of which can be moved inwardly until the inner end abuts a seal and closes a high pressure chamber, thus preventing further movement. This accommodates any necessary movement of a valve towards its closing position to ensure proper closure. Consequently, net-shaped cams wherein the base circle is not necessarily accurately concentric may be used. A leaf spring ensures opening of the chamber when the base circle of the cam is next reached.
