Abstract:
A radial vane rotary power device comprising a stator and a rotor assembly rotatable about an axis of rotation of an end shaft protruding through a front end wall portion of the stator;wherein the stator comprises: an external stator portion defining an internal volume, the external stator portion comprising the front end wall portion and a back end wall portion; the front end wall portion comprising a central throughhole for receiving the end shaft, and an internal cylindrical stator portion projecting from the back end wall portion into the internal volume along an axis of rotation of the device, the internal stator portion having at least one passageway formed therein, the at least one passageway comprising an intake channel parallel to the axis and communicating with at least one radial intake port formed in a peripheral wall of the internal stator portion, and wherein the rotor assembly comprises: a block comprising a central cylindrical bore for receiving the internal stator portion, the block rotatable within a rotor chamber portion of the internal volume lying between the internal stator portion and the external stator portion, the block comprising radial compartments equidistantly spaced apart about the axis of the device, each of the radial compartments open to a peripheral surface of the block, each of the radial compartments having a respective inner opening communicating with the at least one radial port in the peripheral wall of the internal stator portion during the course of each rotation of the rotor assembly; and radially slidable vanes, each of the vanes disposed in a respective slot within the block in alternating relation with the radial compartments.
