Abstract

PURPOSE: To reduce power consumption by a method wherein an actuator is driven by utilizing a pressurized oil stored in an accumulator through the operation of an oil pressure pump and in case the required quantity of pressurized oil is already stored in the accumulator, the oil pressure pump is stopped.
CONSTITUTION: The pressurized oil is stored in the accmulator 7 through the operation of the oil pressure pump 2 and when the pressure within a pipe line 4 including the accumulator 7 reaches a predetermined value assigned for a pressure sensing switch 9, the oil pump 2 is stopped and the pressure in the pipe line 4 is maintained by a check valve 6. In case where a servo-valve 10 is switched, for example, to A side through a control signal from outside, the pressurized oil from the accumulator 7 is supplied into a rod chamber in a cylinder 5 via a pilot check valve 11 and a pilot check valve 12 is opened. Accordingly, it becomes possible to drive away the pressurized oil in a head chamber in the cylinder 5 and to move a piston downward.
