<p>An improved fluid pump having two or more cylindrical eccentric or elliptical rotors drive connected to revolve together at identical angular velocities, and positioned in cylindrical chambers for compressing fluids therein. The pump includes separate intake ports and discharge ports to and from the chambers allowing the pump to be used as a single stage pump or by connecting the discharge port of one chamber with the intake port of the other chamber the pump can be used as a two stage pump for increased pressure with less volume.</p> |
