Abstract

A fluid-actuated rotary actuator includes a housing having a tubular body extending in an axial direction, in which is provided a drive piston assembly for driving a rotatably mounted output shaft, which extends perpendicular to the axial direction through the tubular body and the axial end of which is routed out of the tubular body at an upper wall section of the tubular body, further including a magnet assembly associated with the axial end of the output shaft and receiving a rotary movement of the output shaft, and further including a position feedback device configured to detect the magnetic field generated by the magnet assembly and to provide, in accordance with the detected magnetic field, a position signal corresponding to a position of the output shaft, wherein the position feedback device is located in a receptacle chamber formed in the upper wall section of the tubular body.
