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.
Claims5
An abutment rotary pump comprising:
- a stator defining a closed chamber having a continuous inner wall, with an intake and an exhaust port being formed in the inner wall at spaced-apart locations;
- an abutment pocket formed in the inner wall located between the intake and exhaust port locations;
- and
- repelling magnets having a clearance between faces with the same polarity facing each other;
- wherein the repelling magnets positioned above an abutment to exert pressure on the abutment to continually contact a rotating rotor;
- wherein the abutment affixed in the abutment pocket.
