Abstract
PURPOSE:To reduce displacement and to save pressure boosting liquid, by controlling a pressure lowering valve preferentially to a pressure boosting valve and performing automatic control over the pressure lowering valve and pressure boosting valve so that their opening extents are specific to set pressure. CONSTITUTION:High-pressure liquid produced by a pressurizer 1 is controlled by the pressure boosting valve 5 and when the flow rate is high, the valve operates so as to increase the pressure boosting speed; and the pressure lowering valve 6 provided on an air discharging side, on the other hand, controls the flow rate of discharged gas and the valve operates so as to increase the pressure lowering speed when the flow rate is high. They are controlled by an arithmetic circuit 2 for control. Thus, the pressure lowering valve 6 operates associatively so that the amount of discharged gas is constant to generated pressure under the control. Reference pressure is controlled to desired set pressure in a short time, the amount of discharge gas is reduced, and the pressure boosting fluid can be saved.
