Abstract

PURPOSE: To decrease a rate of depending on oil hydraulic power in steering operation at high speed, by providing a bypass conrol valve in a circuit bypassing both chambers of an actuator, operating said valve to a state of power-on at low speed and operating the valve to a state of power-off at high speed.
CONSTITUTION: There is provided a bypass control valve 10 bypassing both chambers 1a, 1b in an actuator 1. This valve 10 comprises a cylinder 11 and spool 12 reciprocating in the cylinder, and the cylinder 11 is provided with a port A', connected to a port A of the actuator 1, port B', conected to a port B, port T, connected to a tank, and port P, connected to a passage between a flow regulating valve 5 and serve valve 4. If engine speed increases, a feed amount of oil is reduced by the valve 5, then the valve 10 moves the spool 12 toward the port P due to the reduction of oil pressure operated to the port P and opens the ports A', B'. In this way, the both chambers of th actuator 1 are bypassed and released from oil hydraulic power.
