Abstract: A hydraulic lash adjuster includes a cylindrical body having a central cylindrical bore. A hollow plunger is reciprocable in the bore and includes a reservoir chamber therein. The plunger has a close clearance with the bore. A high pressure chamber is defined by the plunger and a closed end of the bore. An orificed wall of the plunger separates the reservoir chamber from the high pressure chamber. A check valve is disposed in the orifice for allowing one-way flow of oil from the reservoir chamber to the high pressure chamber. A plunger spring disposed in the high pressure chamber urges the plunger away from the closed end of the bore. A seat is disposed at an end of the plunger distal from the high pressure chamber. The plunger includes a circumferential groove proximate the seat for holding oil to maintain an oil seal in the clearance to limit leakage of air through the clearance.

Abstract: A hydraulic reverse spring valve clearance compensation element (RSHVA) for a valve train of an internal combustion engine comprising: a housing (2), which has a blind bore (3), in which a piston (4) is guided with a tight, sealing clearance, the piston (4) comprises a lower piston part (4a) with a lower piston head (5), which together with the blind bore (3) defines a high-pressure chamber (7), whilst a low-pressure chamber (8) is situated above the lower piston head (5); the pressure chambers (7, 8) being connected by a central axial bore (10) in the lower piston head (5), which is controlled by a control valve (11) arranged on the underside (23) of the lower piston head (5); the control valve (11) comprises a control valve ball (19), upon which a control valve spring (20) acts in the opening direction and the lift of which is limited by a lift-limiting stop (24) of a valve ball cap (21), whereby an RSHVA, the idle lift of which is as independent as possible of the viscosity and hence of the temperature of the lubricating oil is to be created and is achieved in that temperature-sensitive means influencing the closing time of the control valve (11) are provided, which lead to a closing time of the control valve (11) that is largely independent of the lubricating oil temperature of the internal combustion engine.

Abstract: The invention proposes a valve train (1) of an internal combustion engine comprising a tappet (7) and a tappet pushrod (1) that is actuated by said tappet (7), said tappet pushrod (1) being at least partly hollow and comprising on one end (3), a first support (4) for a pressure piston (5) of a hydraulic lash adjuster (6) of said tappet (7) that follows a periodic driving element such as a cam. A second support (9) for a follower member (2) such as a rocker arm is arranged on a further end (8) of the tappet pushrod (1). The first support (4) comprises a passage (10) for hydraulic medium that can be routed out of the pressure piston (5) during operation of the internal combustion engine into an interior (11) of the tappet pushrod (1), a one-way valve means (12) being installed in the tappet pushrod (1) for retaining a hydraulic medium column during a standstill of the internal combustion engine. In this way, an additional reservoir for hydraulic medium is created that serves for the rapid filling of the pressure piston (5) immediately after a re-starting of the internal combustion engine.

Abstract: A switch element (1) is proposed for valve shut-off, fabricated as cam follower for a plunger rod valve drive of an internal combustion engine, having an outer part (2) and an inner element (4) axially movable in its bore (3) and with rotational security (15) relative to the guided inner element (4). The outer part (2), inside the bore (3), has an annular groove (6), and the inner element (4) has a radial bore (7) with two diametrically opposed pistons (8), which to couple the elements (2, 4) in their axially remote relative position achieved by a lost-motion spring (5) are displaceable towards the annular groove (6). On their cam-side under side, emanating from their radially outward, bulbous face, the pistons (8) segmentwise comprise a plane transverse surface as contact area for a facing under side (27) of the annular groove (6). The latter is intersected by two diametrically opposed oil ports (11) running offset 90° from the pistons (8) in circumferential direction. In addition, the outer part (2) has means (13) for rotationally secured guidance of the switch element (1) relative to a surrounding structure.

Abstract: A switchable cam follower, comprising two relatively movable, e.g., telescopable, units which can be connected via a coupling which engages over a dividing face between the units such that there is a large valve stroke. It is possible to generate no valve stroke or a small valve stroke if the coupling does not engage. At least one spring, which can be loaded compressively or torsionally, acts as a lost motion spring between the units. A compression limiting device impedes movement of the lost motion spring to the blocked position. In an incorrect switching operation in which the coupled units move undesirably toward each other and in a sudden manner under the influence of a valve spring force, movement of the spring into the “blocked” position to become seated is prevented by the limiting device.

Abstract: A hydraulic valve lifter including venting means to assure venting of air through the lifter and filling thereof with oil during pre-start filling of the engine oil galleries after engine assembly. Patterning of a hemispherical pushrod seat surface, and/or patterning of either or both of the mating surfaces of a pushrod seat and a piston, permits air purged from the engine through a pushrod to be vented through the lifter. Such means may be temporary or permanent and may include coatings of the surfaces with materials that are destroyed by engine action after starting. Permanent means may include surface grooves in the mating surfaces and/or small-diameter passages between the hemispherical seat surface and the cylindrical outer surface of the pushrod seat. Venting means in accordance with the invention is useful for both valve-deactivating and non-valve-deactivating valve lifters.
