Inner and outer rotor has two vanes each, rotating in the same direction with variable angular velocity 90 out of phase.
Each chamber expands and contracts twice per revolution -> Enables high capacity per unit.
Each revolution vields 8 full compressor/pump strokes.
Suction/exhaust are formed in four voids between vanes (arranged in front and back of barrel or on sides).
The technology is ready for market and well suitable for applications such as: booster pump, mud pump, CO2 pump, heat pump. wet gas compressor.
