Abstract

Fluid handling mechanism has a vane with parallel side edges coupled to a crank at one end and to an obliquely transverse guide track at the other end. The vane is closely runningly fitted, between parallel side walls and curved top and bottom walls, executing a longitudinally moving line contact with the curved walls in conjunction with irrotational, purely linear, fluid flow. This contact may range from zero to a substantial clearance. Flow is combined fluidynamic fan effect and positive displacement. The positive displacement portion is increased when two such mechanisms are assembled tandemly, in series, with the vanes piano-hinged together. The four walls form a duct, the ends of which may be ported or valved. The duct may also be closed at its ends to constitute a chamber, allowing the mechanism to serve as a closed cycle regenerative gas engine. Mechanism provides interconversion of fluid and mechanical energy for ship propulsion, generation of hydro-electric and wind power, gas compression and evacuation, cryogenic machines, and steam and compressed air turbines.
