転ベーン式ポンプ。 It has a center case, a rotor having vanes that is supported by bearings at both ends and rotates within the center case, and side cases that surround both end surfaces of the center case, and the volume of the space changes as the rotor rotates. In a rotary vane type pump that performs a pumping action, the rotor is driven by an electric motor fixed to a side case of the rotary vane type pump via an intermediate case fixed to the electric motor, and the rotor is driven by an electric motor fixed to the side case of the rotary vane type pump via an intermediate case fixed to the electric motor. The coupling part between the shaft and rotor shaft is sealed, and the sealing part is divided into two chambers by leaving a small area communication hole by the outer periphery of the bearing box provided in a part of the intermediate case and a part of the side case. A rotary vane type pump characterized in that a discharge hole of the rotary vane type pump is communicated with the side case side of a sealed part divided into two parts, and an exhaust hole communicating with the outside atmosphere is provided on the middle case side. .
