<p>A noise-minimized pressure reducing valve valve closure member an axial guiding tappet which is formed at its end as a spherical segment, and the diameter of which is adapted to the diameter of an inner bore in the control piston. Along with another valve tappet and a generous dimensioning of the cross-sections of flow passages, axial and radial vibrations of the valve closure member are effectively reduced or attenuated. To increase the tightness of the pressure reducing valve, for example, the closure member may comprise two closure elements, one of them is made of rubber, while the other one is made of metal. The metal closure element ensures exact pressure control, while the rubber closure element ensures increased tightness.</p> |
