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 having a substantially oval cross-section perpendicular to the axis, the internal volume bounded by front and back external stator portions, the front external stator portion comprising a central throughhole for receiving the end shaft; the external stator portion further comprising a cam track disposed about the internal volume in a plane perpendicular to the axis, the cam track open to the internal volume; an internal cylindrical stator portion centrally projecting from the back external stator portion into the internal volume along the axis of rotation, the internal stator portion having at least one passageway formed therein, the at least one passageway comprising an intake channel extending along 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 portion 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 a selected number, greater than one, of radial compartments equally spaced apart about the axis of the device, each of the compartments open to a peripheral surface of the block, each of the compartments having a respective inner opening for communicating intermittently with the at least one radial port in the peripheral wall of the internal stator portion as the rotor assembly rotates, the rotor assembly further comprising the selected number of radially extending vane assemblies slidably disposed in respective slots within the block in alternating relation with the radial compartments, each of the vane assemblies comprising a respective stub extending radially outward from a body portion of the respective vane, the respective stub retaining a respective cam follower captured in the cam track.
