PURPOSE: To control a fluid control circuit with the best characteristic by selectively feeding at least a portion of the pressurized fluid discharged from a pump into a power steering fluid circuit or other fluid control circuit by a direction selecting means.
CONSTITUTION: The first pump 29 for discharging pressurized fluid into a power steering 44 and the second pump 30 for discharging pressurized fluid into a compliance steering controller 46 are installed. Two direction selecting valves 33 and 34 feed pressurized fluid discharged from the second pump 30 into the power steering apparatus 44 when a car travels at a low speed. The pressurized fluid discharged from the first pump 29 is fed into the compliance steering controller 46 when the car travels at a high speed. Therefore, the power steering apparatus 44 and the compliance steering controller 46 can be controlled with the best characteristics.
