Hydraulic pressure peak blocking valve for power-assisted steering system of motor vehicles is constructed like gear pump without drive

摘要

The hydraulic valve is fitted into the connection duct from a pressure source (2) to a hydraulic working cylinder (3). It is constructed like a gear pump without drive. It has two gears (12,13) with a number of teeth, which is adapted to the requirements regarding flow volume and inertia momentum. The gears mesh with each other and engage mainly on a housing wall (11).
