Abstract

A hydraulic power-assisted steering system for motor vehicles has provision for damping hydraulic oscillations in the steering system while retaining satisfactory suction conditions for the working fluid. The system comprises a pump, a steering valve accommodated in a housing 1 and a power cylinder 4 in which a power piston 7 is slidable and forming two pressure chambers 8 and 9. Ducts 10 and 11 respectively connect annular channels 12, 14 in the steering valve housing 1 to annular channels 13, 15 respectively communicating with the pressure chambers 8 and 9. Hollow non-return valves 16 are screwed in the housing 1 of the steering valve and in parts 3, 5 of the power cylinder housing. The interior bore 17 of the valve 16 receives a valve disc 19 which is urged into a valve closing position against a seat 23 by a weak compression spring 21 and which is provided with a throttle hole 20. Transverse bores 18 enable flow of the working fluid through the valve. The flow is substantially unimpeded in one direction (arrow), but is throttled in the opposite direction.
