Abstract:
A rotary vane machine for industrial scale pressure amplification of gaseous and/or vaporous fluids and comprising:a stationary containment cylinder with circular bore and installed with radially projecting throughput fluid induction and throughput fluid discharge ports within its axial length; an end closure structure mechanically secured at each axial end of aforesaid containment cylinder with each said end closure structure installed with a rotational bearing coaxially aligned with the bore axis of aforesaid containment cylinder, with bearing lubricant supply and discharge ports, and with a condensate discharge port; a bearing carrier mechanically secured at each outermost axial end of aforesaid end closure structure with each said bearing carrier installed with a rotational bearing aligned to be parallel with but radially displaced from the bore axis of aforesaid containment cylinder, with bearing lubricant supply and discharge ports, and with an internal thermal control and lubrication media port; a rotational shaft installed within aforesaid containment cylinder proportioned to axially extend through, and be radially and axially constrained by aforesaid rotational bearings installed in aforesaid bearing carriers and with one or both ends configured to interface with an external rotational power source; a rotational armature concentrically secured on aforesaid rotational shaft within aforesaid containment cylinder, consisting of a structural annulus with an integral closure disk at each axial end and with each said closure disk featuring axially aligned thermal control and lubrication media ports and axially aligned condensate discharge ports; a surface area augmentation slot installed at each of twelve centers uniformly distributed around the inner periphery of aforesaid structural annulus with each said area augmentation slot proportioned to extend through the axial length and partially through the radial thickness of aforesaid structural annulus; a radial vane slot installed on each of twelve centers uniformly distributed around the circumference of aforesaid rotational armature with each said radial vane slot equally distanced from each adjacent aforesaid area augmentation slot, with each said radial vane slot proportioned to extend through the axial length of said rotational armature, extend through the radial thickness of said structural annulus, and accommodate one radial vane; a radial vane installed in each aforesaid radial vane slot and proportioned to extend through the axial length of aforesaid rotational armature and radially extend through the radial thickness of the structural annulus of aforesaid rotational armature; a radial vane support linear bearing segment slot installed in each face of each aforesaid radial vane slot with each said radial vane support linear bearing segment slot proportioned to extend through the axial length of aforesaid rotational armature and partially through the radial depth of aforesaid radial vane slot; a radial vane support linear bearing segment installed in each aforesaid radial vane support linear bearing segment slot with each said radial vane support linear bearing segment proportioned to extend through the axial length of aforesaid rotational armature and be constrained by the aforesaid radial vane support linear bearing segment slot and the surface of the adjacent aforesaid radial vane; a radial compression spring slot installed in one face of each aforesaid radial vane support linear bearing segment slot with each said radial compression spring slot proportioned to extend through the axial length of aforesaid rotational armature and partially through the radial depth of aforesaid radial vane support linear bearing segment slot; a radial compression spring assembly installed in one face of each aforesaid radial vane slot and with each said radial compression spring assembly axially proportioned to extend through the axial length of aforesaid rotational armature and radially proportioned to maintain resilient pressure contact of one aforesaid radial vane support linear bearing segment with the adjacent aforesaid radial vane; a radial vane edge seal individually installed on the radially outermost axial edge of each aforesaid radial vane with said radial vane edge seal configured to feature an axial bifurcation on its outermost axial edge, axially proportioned to extend through the axial length of aforesaid radial vane, and radially proportioned to maintain resilient contact with the bore of aforesaid containment cylinder; a radial vane constraint ring installed at each axial end of aforesaid rotational armature with each said radial vane constraint ring featuring a circular cross-section with its outer diameter proportioned to closely approach the bore of aforesaid end closure structure and its inner diameter proportioned to permit unconstrained axial passage of aforesaid rotational shaft; a circumferentially continuous flange integrally installed on the outer periphery of each aforesaid radial vane constraint ring with said circumferentially continuous flange diametrically and axially proportioned to enshroud the axial ends of aforesaid radial vanes and with said circumferentially continuous flange fitted with radially oriented condensate discharge ports; a circumferentially continuous flange integrally installed on the inner periphery of each aforesaid radial vane constraint ring with said circumferentially continuous flange axially proportioned to extend through and be radially and axially constrained by aforesaid rotational bearings installed in the adjacent aforesaid end closure structure; a bearing block individually secured on each axial end of the radially outermost axial edge of each aforesaid radial vane with each said bearing block proportioned to maintain an area of bearing contact with the inner surface of the aforesaid circumferentially continuous flange on the outer periphery of aforesaid radial vane constraint ring; an axial seal ring installed at each axial end of aforesaid rotational armature with each said axial seal ring circular in cross-section, its outer diameter proportioned to make a constrained but sliding fit within the inner surface of aforesaid continuous flange on the outer periphery of aforesaid radial vane constraint ring, with its radial face width proportioned to close the axial ends of aforesaid radial vane slots, and with condensate discharge ports installed on its axial face; a circumferentially continuous channel coaxially installed on one axial face of each aforesaid axial seal ring with said circumferentially continuous channel oriented to face the adjacent aforesaid radial vane constraint ring and proportioned to accommodate an axial compression spring; an axial compression spring axially installed within each aforesaid circumferentially continuous channel radial in each aforesaid axial seal ring and with each said axial compression spring proportioned to maintain resilient axial pressure contact of aforesaid axial seal ring with the axial end of aforesaid rotating armature.
