发明名称 Hydraulic pilot valve piston - has piston face bore with control edge acting with housing control apertures
摘要 <p>The valve acts to limit a hydraulic control flow, branched-off a hydraulic working flow, and for the hydrostatic stroke limitation of a hydraulically and axially pressure-charged piston. The piston has a ring-shaped bore with an internal control edge on the end surface which faces a spring chamber. The stroke limitation surface of the housing has control apertures. The apertures are positioned so that during the end phase of the movement of the piston towards the control apertures, an adjustable gap is formed between the spring chamber and the control apertures, by the ring surface on the piston, and the stroke limitation surface. The external dia. of the throttle gap is larger than that of the sealing section of the piston.</p>
