<p>The invention relates to a revertible pneumatic or hydraulic rotary device destined to build pumps and engines. According to the invention, the revertible pneumatic or hydraulic rotary device ensures the conversion of the pressure of a fluid into mechanical work or the conversion of the mechanical work into pressure by the fact that the rotary pistons (6) are mounted inside the rotor (2), in some slots (a) having the shape conjugated with that of the rotary pistons (6) and which are closed at the inner part of the rotor (2) by an extension (b) of the rotor body (2), the slots (a) surrounding some pieces (c) in the shape of a cylindrical sector, making one piece with the rotor by the above-mentioned extension (b), the rotor (2) and the extension (b) together with each piece (c) define a cylinder which performs the sealing.</p> |
