Abstract

In a power steering system including a pump 1, a pressure reservoir 2, a steering valve 5, a working cylinder 10 and a return tank 11 there is provided in the supply from the pump 1 and pressure reservoir 2 to the steering valve 5 a pressure reducing valve 12. The forces acting on the valve 12 are a spring 17 and the pressure to the cylinder 10 against the pressure to the valve 5. The valve 12 acts to maintain a constant pressure gradient at the control edges 26, 27 of the steering valve 5, and the system has small leak oil losses. In a modification, the valve 12 is a seat valve. <IMAGE>
