    Abstract: A tappet (1) having a hydraulic element for compensation for play (7), in which a forced opening of its check valve (15) is produced in the course of a base circle area alpha of the actuating cam (5). In accordance with the invention, this is achieved in that a closing member (16) of the check valve (15) is actuated by a final control element (21). This final control element (21) comes through a base (3) of the tappet (1) and co-operates with a groove (22) on the external casing (23) of the cam (5). This groove (22) stretches along the entire perimeter of the cam (5) with the exception of its base circle area. When the base circle area alpha is opposite the base (3), a forced opening of the closing member (16) results. In this way, undesirable discharge of the gas exchange valve, which is actuated by the tappet (1), and/or an opening of this valve by opening movements undesirably directed by the cam (5) against the element for compensation for play (7), can no longer ensue in the basic circle area alpha of the cam (5).

    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: The invention relates to the compensation of undesired overpressures in a high-pressure chamber (14) of a clearance compensator as may, for instance, be applied to cam followers or belt or chain tensioners. To this end, in the high-pressure chamber (14) there is an elastic or axially movable component (21, 24), the compressibility or axial mobility of which tends to enlarge the high-pressure chamber (14) to reduce the undesired overpressures.

    Abstract: The invention concerns a hydraulic valve-tappet for internal-combustion engines, the tappet having a cup-shaped housing (1) with a cylindrical wall (2). The aim of the invention is to reduce the weight of the tappet in the simplest way. This aim is achieved by virtue of the fact that the wall (2) of the tappet housing is pierced by window-like apertures (12).

    Abstract: A cup tappet with a hydraulic adjustment component, which can be used in the valve drives of combustion engines. The cup tappet consists basically of a short staple-reinforced duroplastic or thermoplastic synthetic resin mass with a bottom plate on the cam side of higher hardness and tenacity. The oil supply of the hydraulic adjustment component (5, 6) is effected either through the cam by means of a bore hole (10) in the bottom plate (4), or by means of small diameter steel tubes (19) which are glued or pressed into corresponding bore holes in the casting (1). The mass of the cup tappet is considerably less than that of conventional cup tappets made of steel. It therefore permits higher RPM's and shorter valve control times and, as a result, greater motor efficiency.

    Abstract: A valve operating mechanism includes a pin housing housed in a lash adjuster and a lash adjustment chamber. A sync pin is slidably received within the housing between an activating position and a deactivating position. A ball valve assembly is provided within the housing for communication with the chamber, and is moveable between an open position and a closed position. The valve operating mechanism is operable in an active mode and a deactive mode. In the active mode, the sync pin is in the activating position, a valve is in an active state and the valve operating mechanism is configured to adjust valve lash. In the deactive mode, the sync pin is in the deactivating position and the valve is in a deactive state. The valve operating mechanism is configured to generate valve lash to allow the operating mechanism to move between the active mode and the deactive mode.
