ABSTRACT:
A pair of flow restricting orifices regulate flow from a main engine driven pump through a control valve and steering wheel metering device to a servo motor in a vehicle steering system. Under emergency conditions, an additional flow restricting orifice connects the downstream side of one of the aforementioned pair of orifices to a flow dividing valve. The flow dividing valve connects a reserve pump in parallel with the main pump to augment the supply of pressure medium and sustain a minimal operational steering speed under control of the differential pressure across the other of the pair of orifices, which then dominates control of the supply of pressure medium to the servo motor through the additional flow restricting orifice while there is no flow through said one of the pair of orifices.
