ABSTRACT A casing is made parting along its longitudinal axis and accommodates a coaxially mounted flexible tu- bular chamber. Spacer inserts are provided between part- ing halves of the casing and have a trapezoidal cross- section with the larger base of the trapezium bearing against the flexible tubular chamber and the sides bear- ing against the inner surface of the casing wall. A pair of nipples are provided for supplying fluid to the interior space of the flexible chamber and for air escape therefrom. The powered member has a means for attaching each end of the flexible tubular chamber to a head of the nipple, said means being formed by a pair of cylindrical bushings interconnected by means of a tenon and mortise joint which are located in the casing and define a central passage having its axis aligned with the casing axis. Walls of the passage in a plane drawn in parallel with the casing axis are in the form of a pair of truncated cones having their bases facing towards each other. One generant of the conical surface of the passage extends substantially in parallel with the generant of one conical surface of the nipple head and the other generant of the passage extends substantial- ly in parallel with the other generant of the other coni- cal surface of the nipple head. The invention may be used as a compact actuator in pries, powerful jacks and guillotines in the mechanical en- gineering and in the metal machining.
