The device comprises a casing (1), two oppositely oriented chambers (2, 3) located in it and interconnected through a pipe (4). Each chamber (2 or 3) houses a piston consisting of an elastic sleeve (10 or 11) one end of which is turned inside out and fixed to the internal surface of the pipe (4) at the point of its connection with the chamber (2 or 3). Each piston is kinematically connected with a working organ (7) by means of a shaft (5 or 6) mounted inside the chamber (2 or 3), one end of which is kinematically connected with the working organ (7), and by means of a drum (8 or 9) connected with the other end of the shaft (5 or 6) and provided with a reversing mechanism. The other ends of the sleeves (10 and 11) are fixed to the drums (8 and 9). A pressure chamber consisting of the cavities of the chambers (2, 3) and of the pipe (4) is connected to a system (14) for feeding the fluid medium. |
