Abstract:
A supercharged radial vane rotary power device comprising:an end shaft extending along a rotation axis; a rotor assembly rotatable about the rotation axis; and a stator comprising: a front stator portion having the end shaft journaled therewithin, the front stator portion joined to a back stator portion along respective mating surfaces to form an internal volume containing the rotor assembly; the back stator portion comprising a central inwardly projecting cylindrical portion comprising at least one channel comprising an intake channel communicating with at least one radial intake port formed in a peripheral wall of the central inwardly projecting portion; and wherein the rotor assembly comprises: a rotor block having the end shaft extending therefrom, the end shaft coupled to the rotor block by an axial fan portion comprising a plurality of fan blades extending radially across an intake opening communicating with a central bore for receiving, with rotational clearance, the central inwardly projecting cylindrical portion of the back stator portion; the rotor block rotatably carried by the stator; radial compartments equidistantly spaced apart about the rotation axis, each of the radial compartments open to an outer peripheral surface of the rotor block, each of the radial compartments having a respective inner opening intermittently communicating with the at least one radial port in the peripheral wall of the central cylindrical inwardly projecting portion of the stator during the course of each rotation of the rotor assembly; and radially extending vane assemblies slidably disposed in respective slots within the rotor block in alternating relation with the radial compartments, each of the vane assemblies comprising a respective cam follower engaging a cam track define by grooves formed in mating surfaces of the front and back stator portions.
