摘要： In a valve timing gear of an internal combustion engine having hydraulic valve clearance adjusting elements (21), each element (21) comprises a rotationally symmetrical housing (22), which is guided so that it is longitudinally displaceable in a seat in the engine and at one axial end of the element (21) is acted upon by a cam of a camshaft. The element (21) comprises a piston (24) which is axially displaceable in the housing (22) and is non-positively connected either directly or indirectly to an engine gas exchange valve. A control valve (31), which has a closing member (39) and a valve seat for this formed on the piston (24), is arranged axially between the housing (22) and the piston (24). A reverse-spring element is used as valve clearance adjusting element (21), that is to say an element the control valve (31) of which comprises a control valve spring (30), which is supported by one end on the piston (24) and by the other end on the closing member (39).

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.
