FEEDBACK SYSTEM FOR SERVO VALVE SYSTEM

摘要

PURPOSE: A feedback system for a servo valve system is provided which is in the form of a rotary-disk valve system. CONSTITUTION: A feedback system for a servo valve system consists of a rotary-disk valve (1) and a control bush (2) that coaxially surrounds the rotary-disk valve and can be pivoted in relation to it, for use notably in power-steering units in motor vehicles. On a shaft (9) situated on the side of the rotary-disk valve, V-grooves (10) are arranged axially into which feedback elements (15) can be pressed by adjustable hydraulic pressure. These feedback elements are radially located on a section of bush (11) that is connected to the control bush (2) in such a way that it cannot be rotated.
