Abstract

PURPOSE: To reduce shock to the body of a vehicle and also the occurrence of unusual sound by providing a control valve circuit between a forward side circuit and a return side circuit and making the rise of pressure to the forward side slow by bypassing the pressure oil on the forward side to the return side during the beginning time of driving.
CONSTITUTION: Control valve circuits 10 are provided between the first circuit 41 and the second circuit 42 of a motor circuit 4. The control circuits 10 are provided in two pairs in mutually opposite directions between both the circuits 41 and 42, each consisting of a control valve 11, an escape path 12, and a check valve 13. And, the control valve 11 has a control path 14 leading to the path 12, in which when the pressure of forward path in the motor circuit 4 is below a certain value, the control path 14 is opened so as to escape the pressure oil flowing in the forward side circuit to the path 12 to form a low-pressure working region. Then, when the pressure of the forward path is above a certain value, the control path 14 is closed to form the usual motor circuit 4.
