摘要： The hydraulic play compensation device, having an outer cylinder part which is closed on one side by a base and in which a piston element which lies on its inside is guided so as to be longitudinally displaceable, with a guide gap, having an oil pressure space having an oil inlet which supplies the oil supply space, and having a connecting duct controlled by a nonreturn valve between the oil supply space and the oil pressure space. For optimized removal of air which is introduced via the oil inlet, it is proposed that a ventilation path which connects the oil supply space and the guide gap is formed in the piston element downstream of the oil inlet and upstream of the connecting duct.

摘要： The invention proposes a coupling mechanism (1) for relatively movable elements (2, 3) of a switchable cam follower (4) of a valve train of an internal combustion engine, a high lift being obtainable upon coupling of said elements (2, 3) and a lift smaller than the high lift being obtainable upon uncoupling of said elements (2, 3), a first one (2) of said elements comprising a guide bore (5) for at least one coupling piston (6) which, for achieving coupling, can be displaced partly beyond a parting surface (7) between said elements (2, 3) into an aligned reception (8) of a second one (3) of said elements, wherein upon cam lift and coupling of said elements (2, 3), a contact zone (9) between the piston (6) and the reception (8) is clearly spaced from an edge section (10) of the reception (8) on the parting surface (7). This can be implemented in practice, for instance, through a special “backwards” oriented flattened portion (14) on the piston (6). Material loading on the edge section (10) is thus avoided.

摘要： A hydraulic valve lash adjuster for a valve train of an internal combustion engine, for example for an automotive vehicle, said hydraulic valve lash adjuster comprising a piston (2) that is guided for displacement in a piston housing (4) and elastically supported against said housing, said piston (2) comprising a low pressure chamber (3) that communicates via an axial opening (26) in a piston bottom (19) with a high pressure chamber (5) defined by the piston housing (4) and the piston (2), and further comprising a control valve (6) acting between said pressure chambers (3, 5), said control valve (6) comprising a valve closing body (7) that can be brought to bear sealingly against a valve seat (24) that surrounds the axial opening (26) on a piston body undersurface (28) and is received in a closing body cap (9) whose cap bottom (21) acts as a stroke limitation of the valve closing body (7), and said control valve (6) further comprising a control valve spring (8) that loads the valve closing body (7) in opening direction, and, during a collapsing movement between the piston (2) and the piston housing (4), said valve closing body (7) being hydraulically loadable in closing direction against the biasing force of the control valve spring (8) by a pressure build-up in the high pressure chamber (5).To improve the valve lash adjuster so that undesired operational fluctuations are reduced, the valve closing body (7) is configured as a needle-shaped, elongate sealing piston whose valve seat-proximate end comprises a plate-shaped sealing surface (10) that cooperates with a correspondingly configured sealing surface (25) of the valve seat (24) and whose valve seat-distal end comprises a surface of application (12) for hydraulic loading, and the valve closing body (7) substantially fills a space volume of the closing body cap (9) surrounding the valve closing body (7).

摘要： 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.

摘要： The invention relates to a method of setting the ball travel of a valve-closing body, designed as valve ball (6), of a control valve (7) of a hydraulic valve-lash-adjusting element which has a plunger (1) with a plunger head (2) and a central bore (3) in the same, a valve seat (5) being provided at the outer end (4) of this central bore (3), this valve seat (5) being controlled by a valve ball (6), the ball travel of which is limited by a valve cap (8) which has a cap flange (9) and a cap base (11), the cap flange (9) resting with its bearing surface (10) on a base (17) of a recess (13) of the plunger head (2), and a stop (12) of the cap base (11) serving as a travel limit for the valve ball (6). The identical ball travel of the valve balls (6), which is so important for the operating behaviour of the internal combustion engine and for the wear and noise behaviour of its valve train, is achieved in that, after an internal depth dimension (a) of the valve cap (8) has been measured, this internal depth dimension (a) extending from the bearing surface (10) of the cap flange (9) up to the stop (12) of the cap base (11), and after a projecting dimension (b) of a measuring ball (16), lying in the valve seat (5), relative to the base (17) of the recess (13) has been measured, a calculated value of the ball travel (c=a−b) is determined, and in that, after that, a matched valve ball (6) having the ball diameter required for the desired ball travel is selected from a number of valve balls of different, known diameter and is fitted together with the measured plunger (1) and the measured valve cap (8). The measured actual values of the ball travel of the valve balls (6) can also be corrected by subsequently pressing the valve caps (8) in a controlled manner.
