Abstract
PURPOSE: To enable the power consumption to be reduced to the minimum even if a selector valve of which switching pressure is high is used, by arranging a throttle valve between a pump and the selector valve and making it possible for the turning of throttling of said throttle valve to be controlled according to the pressurized fluide which is fed from a control means.
CONSTITUTION: When a selector valve 5 is at neutral position, the spool 22 of a throttle valve 21 is at the left end, and the oil discharged from a pump 1 is returned to a tank 7 with a low pressure necessary for operating the spool 22. When the selector valve 5 is switched (for example to the right position), pressurized oil operates to the chamber 26 of the throttle valve 21 and shifts the spool 22 rightward. Accordingly, the oil pressure in a duct 15 increases and switches a selector valve 4. Thus, when the selector valve 5 is at neutral position, the pump delivery pressure retains a low pressure necessary for switching the throttle valve 21, so even if the selector valve 4 of which switching pressure is high is used, the power loss and the increase of the oil temperatuere can be suppressed to the minimum.
