Abstract
A rotary pump device includes a stator chamber with a cylindrical inner wall having intake and exhaust ports and an abutment mounted therein, and a rotor eccentrically mounted on an axial driven shaft for rotation within the chamber. The rotor keeps continuous wiping contact with the chamber wall while repelling magnets exert pressure on an abutment which maintains contact with the rotor to partition the intake and outlet ports. The repelling magnets act as a spring to assure contact of the abutment on the rotor while the pump is running or on standby. The repelling is caused by locating magnets positioned with similar facing poles in a pocket positioned against an abutment. A full intake/exhaust cycle takes place every 360° of rotor travel.
