Abstract

PURPOSE: To enable an actuator to operate at a stabilized speed by interposing a check valve between the actuator and the first change-over valve with a connecting portion between the actuator and the check valve being connected to a fixed volume cylinder through the second change-over valve.
CONSTITUTION: A check valve 12 is interposed between an actuator 10 and the first change-over valve 6, and a communicating passage 13 between the actuator 10 and the check valve 12 is connected to a fixed volume cylinder 18 through the second change-over valve 16. If the second change-over valve 16 is changed over after a fixed interval of time, a fixed volume of liquid is intermittently flowed out from a return liquid chamber B of the actuator 10 so that a piston 11 is intermittently moved at a constant speed until liquid is completely discharged from the return liquid chamber B. Thus, the actuator can always operate at a stabilized speed irrespective of pressure and temperature of liquid which is introduced into the actuator.
