Abstract
PURPOSE: To correctly stop the actuator, when lowered a delivery pressure of the liquid pressure pump, by providing a check valve of pilot type in a half way of the line, that connects the changeover valve and the actuator, and directly inducting a pilot pressure from the liquid pressure pump.
CONSTITUTION: In a half way of the line that connects a changeover valve 1 and an actuator 2, is prpvided a check valve 5, 6 of pilot type, and a pilot pressure, for operating this check valve 5, 6 of pilot type, is directly inducted from a liquid pressure pump 7. In this way, with a delivery pressure of the liquid pressure pump 7 lowering below a specified value, the check valve 5, 6 of pilot type is closed, and a flow of the liquid, going to the changeover valve 1 from the acuator 2, can be correctly checked. Accordingly, when lowered the delivery pressure of the liquid pressure pump 7, the actuator 2 can be correctly stopped.
