PURPOSE: A flow controller using pressure sensor provides the rotary power of the maximum output by controlling the inflow rate of a sensitivity controller. CONSTITUTION: A main passage(2) connected to a pump(3), a control valve(5) and a sensitivity controller(4) is mounted in a rotary valve(1) for steering. The sensitivity controller(4) controls a flow supplied from the pump(3), thereby improving the characteristic of steering. A pressure gauge(6) connected with an ECU(electronic control unit) is mounted between the rotary valve(1) and the pump(3). When the pressure gauge(6) senses the oil pressure supplied through the main passage(2) from the pump(3) and sends a sensed valve to the ECU, the ECU controls a flow which flows in the sensitivity controller(4) in comparison with the relation of the sensed value and a rotary power. Therefore, the ECU operates a steering system in a proper and smooth condition by the controlled oil pressure. Thus, the occurrence of a noise is eliminated greatly by a smooth action of the oil pressure and the optimum output is obtained by a proper control of the oil pressure. The drive of an electronic control type steering system is smoothed by the optimum output.
