ABSTRACT:
A fluid transport device for compressing or pumping a work fluid comprises a rotating coupling having an off-center first gear, a fixed internal second gear of twice the pitch diameter of the first gear, and a housing having a diametrical channel with a sliding piston disposed therein. A crank-like connector rotatably coupled with the first gear has a depending lug engaged within a hole in the piston and acts to drive the piston to and fro within the channel. First and second chambers are defined to either side of the piston, with the terminal ends of the chambers defined by the wall of the housing each having an egress aperture and an ingress chamber. A slotted depending rim of the coupling alternately obturates the egress aperture of one chamber and the ingress aperture of the other in step with the intake and expulsion stroke of the piston in each chamber.
