Abstract

PURPOSE: To keep pump a always in a stopped state wherever assistance is not required and to enable to operate for assistance readily when it is required, by installing an accumulator and an open and close valve on midway of the fluid passage connecting the pump to the control valve.
CONSTITUTION: To the shaft 22 of the steering wheel 21, a steering torque detector 23 is arranged, and is connected with the control device 39 which controls the open and close valve 35 installed in the fluid passage 32 connecting the pump 25 and the power steering. In the flow line between the open close valve 35 and the pump 25, an accumulator 37 is connected through a flow control valve 36. A pressure switch 38 is installed to the accumulator 37 to operate the pump 25 when the pressure in the accumulator 37 is lower than certain determined value. Therefore, power assistance can be obtained quickly even when the outlet pressure of the pump 25 is low at the starting of the pump.
