Abstract
A hydraulic rotary actuator has a housing with at least one rib on its inside wall and a motor shaft with at least one vane on its outside shell surface, whereby the housing with its ribs and the motor shaft with its vanes form a working chamber which is closed off on the ends by means of a cap. A gasket is located between the motor shaft and a component of the housing to seal the working chamber off from the environment. The gasket and housing component can preferably form a latching mechanism therebetween to retain the gasket in position during assembly of the rotary actuator.
