In a rotary actuator comprising a housing containing a piston and having a cover and a base, thread-like guide grooves in the piston, a shaft having a transverse axis and being rotatable about an axis of the rotary actuator which transverse axis engages into the guide grooves, and torque support engaging into guides in the piston, which torque supports are anchored in the housing, wherein the transverse axis on both ends comprises bushes contacting raceways of the guide grooves, each bush is cambered and each raceway is configured with an undercut corresponding to the cambering.

A valve device includes a control device adapted to control a valve without being supplied with electricity. The control device includes at least one rotatable control cam having an outer periphery with a concave and convex shape, and a driving device adapted to rotate the control cam only in a first rotational direction, out of the first rotational direction and a second rotational direction opposite from the first rotational direction, by being supplied with a pressurized medium. The valve is placed such that a switch portion comes in contact with the outer peripheral portion of the control cam, in order that the valve is opened and closed by the control cam being rotated.
