Abstract

The reversible system for the transfer of energy from a fluid to a rotating shaft by a positive closed displacement device is characterized in that it comprises a first stationary unit, consisting of a cylindrical chamber directly connected to the fluid line, a second rotary unit, consisting of a cylin­ drical rotor having radial grooves associated to a shaft which extends through the top and bottom of the first unit, its axis being parallel but not coincident with the axis of the first unit, a third unit formed by a set of rolls which loosely fit into the grooves and are as long as the two first mentioned units, thus ensuring that the pressure of the fluid urges the rolls against the internal surface of the chamber and that the walls of the grooves form tight movable spaces filled with fluid, and the respective volumes being dependent upon the angular position of the rotor in relation to the chamber, the energy of the fluid thus being transferred to the rotating shaft or, vice versa, from the rotating shaft to the fluid.
