ABSTRACT:
A vehicle fluid pressure supply system in which a fluid pressure supply pump (10) is connected via solenoid-operated flow control valve (15) with a plurality of separate fluid pressure operated circuits(A, B, C) each operating separate functions of the vehicle. Detectors (25, 26, 27, 30 to 35) are provided for detecting the current operative state and the fluid pressure supply status of each circuit, and an electrical control unit (28) means which receives signals from the detectors operates the control valve to direct available pump flow to the appropriate circuit to maintain each circuit at least at a minimum pressure level required to operate the associated function.
