Abstract (en)
A rotary actuator operated by a pressure fluid; the actuator comprises an annular chamber (11) in which a piston member (12) reciprocates, said piston member (12) being operatively connected to an external power-transmission member (17) through an annular slit (21) provided with a flexible sealing strip (25). The power transmission member (17) is rotatably supported coaxially to the annular chamber (11) and is loosely connected to the piston member (12).
