Abstract: The invention proposes a push-rod valve train having an adjustable valve tappet (1). This has an outer part (2a, 2b), an inner part (8) and a lost-motion spring (10), which forces the inner part (8) towards a relative position, at least one retainer ring (23), which is fixed in an annular groove (21) of the outer part (2a, 2b) and which interacts with a stop face (22) of the inner part (8), being provided for fixing the relative position, said retainer ring having lugs (28) extending radially inwards and separated by a fitting gap (27). In this the free movement of the valve push rod (15) relative to the lugs (28) is assured by the provision of a torsional locking means (30a, 30b), which serves to fix the radial position of the fitting gap (27) inside the annular groove (21).

Abstract: A mechanism and method is provided for preventing instantaneous unlatching of a driving and a driven member upon an accidental drop in the hydraulic-holding pressure. One embodiment of the mechanism includes a housing having an inlet port connectable to a substantially sustained high pressure fluid source; and a configured locking pin axially displaceable to an engaged position with respect to the inlet port in response to high pressure fluid entrapped in the housing. The locking pin is spring-biasingly axially displaceable to a disengaged position when the pressure is low. The axial displacement of the locking pin sufficiently overlaps the inlet port to form a variable orifice so that the rate of exhausting of entrapped fluid is variable. In another embodiment, the entrapped fluid is slowly exhausted until a seal length is reduced to zero by the retraction of the locking pin. In another embodiment, latching and unlatching is controlled by pressure pulses. In the latched state, contact between positively-engaged parts negates the need for sustained high fluid pressures.

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 hydraulic lash adjuster (1) for a valve train (16) of an internal combustion engine, said hydraulic lash adjuster (1) comprising a hollow cylindrical housing (2) and a pressure piston (3) that are axially inter-inserted for axial displacement relative to each other, a bottom (4) of the pressure piston (3) comprising a central passage (5) for hydraulic medium from a reservoir (6) enclosed by the pressure piston (3) into a high pressure chamber (8) situated between the bottom (4) of the pressure piston (3) and an opposing bottom (7) of the housing (2), said passage (5) comprising, on an end (9) oriented toward the high pressure chamber (8), a one-way valve (10) that opens toward the high pressure chamber (8), wherein a flexible disk-shaped body (11), that is capable of floating on the hydraulic medium, extends within the reservoir (6). In this way, a “break-through” of air from the reservoir (6) into the high pressure chamber (8) is avoided. During a re-suction process in the lash adjuster (1), the body (11), so to speak, follows an air funnel that is being formed in the reservoir (6) in the direction of the one-way valve (10).

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.

Abstract: PROBLEM TO BE SOLVED: To avoid delaying in the movement of a valve element to a valve closing position, when lowering a plunger.
SOLUTION: A check valve 27 includes a valve port 28 penetrating through a bottom wall 17 of the plunger 12, a retainer 30 arranged in a high pressure chamber 25 and integrally vertically moving with the plunger 12, and the valve element 29 vertically movable between a valve opening position placed on the retainer 30 by separating from the valve port 28 and a valve closing position being above the valve opening position and blocking up the valve port 28 in the high pressure chamber 25. When the plunger 12 is a resting state, the valve element 29 is held in the valve opening position by its dead weight.
