Hydraulic pulse-generating device e.g. for hydraulic systems, has rotary disc valve fitted with servo-motor as drive

摘要

A rotary disk valve is used within a hydraulic system as a pressure- or flow-regulator, especially for generating hydraulic pressure pulses. The rotary disk valve (4) is fitted with an electric servo-motor (5) as drive. For the generation of certain upper and lower threshold values of the pressure pulses, an auxiliary valve (8,9) is provided inside the hydraulic system
