サーボアクチユエータ。 It is slidable in a housing consisting of a cylinder tube with an oil supply port leading to the pump, a rod side cover with a return port leading to the tank, and a head side cover, and is connected to the rod and connects multiple oil passages. a spool slidable within the piston and driven in the axial direction via a ball screw driven by an AC motor and a ball screw nut threadedly engaged with the ball screw; In the direct-acting servo actuator, the return fluid outlet is formed in the rod located on the inner wall of the rod side cover, and the piston is connected to a hydraulic pressure chamber on the rod side in the housing. A flow path is formed that communicates the pressure oil chamber on the head side in the housing with the oil pressure supply chamber through a spool for simultaneously opening and closing the oil path leading to the rod side cover and the oil path leading to the return port of the rod side cover. A direct-acting servo actuator featuring:
