    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.

    摘要: A method for assembling a control valve in a hydraulic valve-lash compensation element, which is constructed for the control drive of an internal combustion engine as a reverse spring element is provided. According to the method, the compensation element is preassembled with a control valve spring (10), a ball (19), and a valve cap (20) of the control valve (11), so that the ball lift (21) caused by the construction of the control valve (11) is greater than a desired value required for the function of the element, after which the actual state of the ball lift (21) is measured and then the ball lift (21) is adjusted by deformation of the valve cap base acting as a contact surface (23) for the ball (19), in order to obtain the desired value of the ball lift (21) of the compensation element. In this way, for all of the compensation elements of the motor, the setting of the no-load lift to a constant value having only very small tolerances can be achieved.
