<p>A device for transforming the energy of a fluid medium into mechanical work comprises a hermetic chamber (1) connected through valves to systems for feeding and evacuating the fluid medium and provided with an opening (4) in which a sleeve (5) of a flexible material is fixed along its perimeter by one of its ends said sleeve being mounted in the chamber (1) with the possibility of its reciprocal displacement in relation to the fixed end so that, during displacement from the initial to the extreme position, a part of the sleeve (5) turns inside out and forms a cavity (9) connected to the chamber (1). The sleeve (5) is connected by its other end to a drum (7) located inside the chamber (1) and mounted on a shaft (6) which is connected in turn, through an overrunning clutch (8), with a reversible mechanism (11). In its initial position the sleeve (5) is wound up on the drum (7).</p> |
