Claims

[Scope of utility model registration request]

Correspondence between the rotating piston spline-engaged with the output shaft and screwed to the casing, the reciprocating piston and switching valve attached to the output shaft, and the pressure chambers on both sides of the reciprocating piston and the switching valve. a communication path that connects the respective ports, a communication path that connects the pressure chamber of the rotating piston and the corresponding port of the switching valve through a sequence valve, and a communication path that is attached to the output shaft and that connects the switching valve in conjunction with the stroke of the switching valve. A torque actuator comprising: a clutch for switching the reciprocating piston; and a directional switching valve disposed in a working fluid supply path for introducing working fluid to the reciprocating piston.
