FIELD: agriculture; milking plants. SUBSTANCE: proposed rotary vane vacuum pump contains stator installed on rolling supports and rotor installed eccentrically relative to stator, with vanes fitted for movement in rotor slots. Stator with side cover and rotor are installed for rotation on fix tubular axle. Driving plate of rotor is fixed, by spring-loaded pins arranged in plate and faces, in holes of side cover and stator. Rotor is provided with channels communicating with suction and delivery spaces of fixed tubular axle formed by longitudinal divider in axle and arranged so that each channel has common side with near slot of rotor. EFFECT: reduced wear of pump parts, energy consumption for pump driving, simplified design. 6 dwg
