摘要： In an aspect of the present invention, an actuation system includes: a pump assembly (11) configured to form a pump chamber; an actuator (6) having first and second chambers and a movable member (42) and configured to convert pressures applied to the first and second chambers into a movement of the movable member; and a valve section (12;13). A controller (7) controls the valve section to open a first flow path between the pump chamber and the first chamber and close a second flow path between the pump chamber with the second chamber, during a discharge period during which the pump chamber is pressurized, in a first mode; to close the first flow path and open the second flow path during an intake period during which the pump chamber is depressurized, in the first mode; to close the first flow path and open the second flow path during the discharge period in a second mode; and to open the first flow path and close the second flow path during the intake period in the second mode.
