  • Plastic vane for a vane-cell vacuum pump
    Patent number: 6655937
    Abstract: A vane cell vacuum pump has a rotor, in which a plastic vane, which with at least terminal part engages the inner wall of the jacket of a pump housing, is guided longitudinally. The body of the vane comprises a duroplastic and is united with the terminal part, of thermoplastic by an injection-molding operation. With the material comprising the body, high mechanical strength is attained, while with the material of the terminal part, high wear resistance and a low coefficient of friction are attained.
