ABSTRACT:
A pump having a limited maximum output pressure is alternately connected to a steering control valve and a pressure storage reservoir charged by the pump under control of a signal pressure operated valve to supply fluid under the maximum pump pressure to a steering servomotor only under high loading conditions. The storage pressure is limited to a value less than the maximum pump pressure to influence operation of the signal pressure operated valve and operate the servomotor under low load conditions.
