Publication number: 20090083959Abstract: 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.Type: ApplicationFiled: September 18, 2008Publication date: April 2, 2009Applicant: SCHAEFFLER KGInventors: Peter Sailer, Oliver Schnell
