Abstract
PURPOSE: To save electric energy considerably, by providing an electromagnetic valve between a servo valve and an accumulator, and thereby eliminating leakage of hydraulic liquid from the servo valve.
CONSTITUTION: Between servo valve 19 and accumulator 16, there is provided an electromagnetic valve 17 which is designed to open gradually when a driving signal is given to the same. Since, with such an arrangement, electromagnetic valve 17 is closed when actuator 20 is not operated, it is prevented that hydraulic liquid is leaked to the outside from accumulator 16 via servo valve 19. Therefore, it is prevented that motor 13 is set into operation by the leakage of hydraulic liquid from servo valve 19, so that electric energy used for charging accumulator 16 can be saved resultantly.
