Abstract

PURPOSE: To lessen the pressure loss of main circuit by providing a solenoid operated valve, which is to be opened when divergence pressure oil is not being taken out, in parallel with a spool valve and a relief valve installed in the main circuit.
CONSTITUTION: A spool valve 11 and a relief valve 16 to be actuated by the differential pressure between the fore and back of a throttle valve 17 are installed in the main circuit 3, and a by-pass circiuit 14 containing a solenoid valve 15 is provided in parallel with this spool valve 11 and relief valve 16. When no divergent pressure oil is taken out of the divergence circuit 7, the solenoid valve 15 is opened, so that the pressure oil from the pump 1 flows through the by-pass circuit 14 and the differential pressure generated between the fore and back of the throttle valve 17 will open the spool valve 11. At this time, the valve opening pressure for the spool valve 11 is approx. 1kg/cm2, so that little pressure in the main circuit will be lost.
