摘要
A vacuum pump includes a housing defining a cavity having an inlet and an outlet; a vane member for a rotary driven movement inside the cavity; a drivable rotor inside the cavity; and a rotatable central shaft extending to the cavity. The vane member is slidably arranged in the rotor. The rotor is rotatable together with the vane member. The central shaft comprises a crank pin configured to engage a respective guiding recess of the rotor for driving the rotor at least along a first predetermined rotational angle.
