    Abstract: An engine tappet is constructed with flat, essentially parallel or conformal bearing surfaces internal of its case for the introduction during no-load operation of a lubricant under pressure to the space between the surfaces, the pressure level of the lubricant being greater than the force necessary to remove lash in the system, to thereby create an oil film between the surfaces that is partially squeezed out during load operations of the cam event to in effect float one part upon the other to reduce rotational friction.

    Abstract: A valve mechanism includes: a support shaft immovably fixed to a main body of an internal combustion engine, a main arm swingably supported by the support shaft; two sub-arms arranged at both sides of the main arm; a coupling support portion swingably supporting and coupling the two sub-arms to the main arm; a cam; and a roller rotatably located in the main arm. Each of the two sub-arms includes: a drive unit pressing and driving a valve; and a contact portion contacting a plunger of a lash adjuster, the contact portion has a curved surface slidably contacting a flat surface formed in a tip portion of the plunger and having an arc-like curved surface shape of which a central axis line corresponds to a central swing axis line of the main arm in a state where the cam abuts on the roller in a base circular portion of the cam.

    Abstract: A lash adjuster includes a body, a plunger which is inserted into the body and has a bottom wall with a valve hole and a peripheral wall having an oil passage hole and an inner periphery formed with a recessed groove, the plunger defining a high-pressure chamber between the bottom wall and the body, and a partitioning member inserted into the plunger. The partitioning member has an oil passage end located above the oil passage hole. The partitioning member has an oil-passage defining portion located opposite the recessed groove and defining an oil passage between itself and a groove face of the recessed groove. The partitioning member defines a low-pressure chamber inside. The low-pressure chamber reserves a hydraulic fluid flowing through the oil passage hole, the oil passage and the oil passage end. The low-pressure chamber causes the reserved hydraulic fluid to flow through the valve hole into the high-pressure chamber.

    Abstract: A lash adjuster in which, when a plunger descends, a valve element moves to a valve-closed position without delay. A check valve (27) has a valve hole (28) penetrating through a bottom wall (17) of a plunger (12), a retainer (30) placed in a high pressure chamber (25) and vertically moving together with the plunger (12), and a valve element (29) capable of vertically moving in the high pressure chamber (25), between a valve-opened position at which the valve element (29) is separated from the valve hole (28) to be placed on the retainer (30) and a valve-closed position which is located above the valve-opened position and at which the valve element (29) closes the valve hole (28). When the plunger (12) is at a standstill, the valve element (29) is held at the valve-opened position by the self-weight.

    Abstract: A hydraulic valve play compensation element for an internal combustion engine is provided as a reverse-spring/free-ball element, with a cylindrical housing, a cylindrical piston (21) guided therein with sealing play and a control valve (20), which is arranged between a low-pressure chamber (22) of the piston (21) and a high-pressure chamber (24) of the housing, on a piston head (25) of the piston and which has a closing body (27), which can contact a valve seat (26) surrounding an axial bore hole (23) of the piston head (25) when carrying out a stroke (28) in the closing direction against the force of a control-valve spring (34) and which can contact a contact surface (29) of a valve cap (30) surrounding the closing body (27) when carrying out a stroke in the opening direction. In a region of the axial bore hole (23) for the closing body (27) there is a narrow guidance surface (32) with gaps, which enable a volume flow of hydraulic medium between the high-pressure chamber (24) and the low-pressure chamber (22).
