Abstract
A rotary actuator (1) comprising a housing (2), which defines a working chamber (3) for actuation with a pressure fluid and having at least partially circular section, a pivoting piston (5) which is arranged sealingly against the inner wall (4) of and rotatable between two end positions in the working chamber, is featured in that the pivoting piston (5) itself is pivotally supported in bearings (16) which are arranged in the housing (2) axially at each side of the working chamber (3), and wherein it comprises means for cooperation with an external rotary shaft, whereby the housing (2) on at least one of its end walls is adapted so as to be contacted against and be fixedly fastened to a corresponding end wall portions of a second rotary actuator housing (2), and whereby these housings are fixable to one another in such a way that the axes (X) of the pivoting pistons of the respective housings are coaxial and that the pivoting pistons thereby are capable of affecting one common outgoing shaft.
