Abstract:
A rotary vane machine for the interrelated manipulation of hydraulic and mechanical energy and comprising:a stationary containment structure consisting of a containment cylinder with circular bore installed with a closure structure at each end and with ports radially and axially oriented and proportioned for optimal induction and optimal discharge of throughput working fluid; a volume compensation valve installed in aforesaid stationary containment cylinder, positioned and proportioned to optimally control the magnitude of function related high-pressure fluctuations in contained working fluid; a volume compensation valve installed in aforesaid stationary containment cylinder, positioned and proportioned to optimally control the magnitude of function related low-pressure fluctuations in contained working fluid; a rotational shaft installed within aforesaid stationary containment structure proportioned to extend through the axial length of aforesaid stationary closure structure with one or both ends configured to interface with an external rotational power system; a rotational armature coaxially secured on aforesaid rotational shaft within aforesaid containment cylinder and configured as a structural annulus with a circular cross-section diametrically proportioned to equal approximately ninety percent of the bore of said containment cylinder; a radial vane slot installed at each of twelve axially aligned centers uniformly distributed around the outer periphery of aforesaid rotational armature and proportioned to extend through its axial length and through the radial thickness of its structural annulus; a radial vane support linear bearing insert slot installed in each face of aforesaid radial vane slot and proportioned to extend through is axial length and partially through its radial width; a radial vane support linear bearing insert installed within aforesaid radial vane support linear bearing insert slot and proportioned to extend through its axial length and its radial width; a radial vane installed in each aforesaid radial vane slot and proportioned to make a constrained sliding fit with the facing surface of aforesaid support linear bearing insert, axially extend through the axial length of aforesaid rotational armature, and radially extend through the radial thickness of its structural annulus; a radial vane edge seal individually installed on the radially outermost axial edge of aforesaid radial vane and proportioned to maintain resilient sealing contact with the bore of the aforesaid containment cylinder; a radial vane sliding-block installed on each peripherally outermost axial end of aforesaid radial vane and secured by a closely fitted rotational bearing proportioned to allow partial relative rotation; a low-friction rotational bearing installed in each aforesaid end closure structure with said low-friction bearing proportioned to radially constrain aforesaid rotational shaft and aligned with its rotational axis parallel to but radially displaced from the bore axis of aforesaid containment cylinder; a radial vane axial constraint ring installed at each axial end of aforesaid rotational armature and configured to feature an axially extended flange on its outer periphery and an axially extended flange its inner periphery; a low friction rotational bearing secured in each aforesaid end closure structure with said low-friction bearing proportioned to radially and axially constrain aforesaid radial vane axial constraint ring and aligned with its rotational axis concentric with the bore axis of aforesaid containment cylinder; a radial vane radial vane radial constraint ring configured as an integral axial extension of the aforesaid outer peripheral flange of aforesaid radial vane axial constraint ring and oriented and proportioned to radially constrain aforesaid sliding block; a wear-ring installed on the axially innermost face of aforesaid radial vane axial constraint ring and proportioned to maintain a radially constrained sliding fit with the facing surfaces of the inner and outer peripheral flanges of aforesaid radial vane axial constraint ring; an axially oriented working fluid transfer port installed at each of several concentric centers around the axial face of aforesaid wear ring; a non-return reed valve installed at each of several concentric centers on the axially outermost axial face of aforesaid wear ring and coaxially aligned with the aforesaid working fluid transfer port; an axial compression spring installed on the axially outermost face of each aforesaid wear ring and axially proportioned to maintain resilient axial bearing contact of the axially innermost axial face aforesaid wear ring with the axial end of aforesaid rotating armature.
