ABSTRACT:
A positive-displacement piston mechanism includes a small rotor integrated with a main axis and biased against a cylindrical large rotor for holding a bearing-housing. Slant sliding slots are formed at facing places in equally divided space between the large rotor and the small rotor. Vanes having an angle are fitted into the slots as if they were bridges, and an inlet and an outlet are provided on side-housings.
