Abstract
A rotating vane vacuum pump includes a housing defining a cavity having an inlet and an outlet, a drivable vane member for a rotary driven movement inside the cavity, a rotor inside the cavity, and a rotatable central shaft extending into the cavity. The vane member is coupled to the central shaft by an eccentric element on the central shaft and movably arranged in the rotor, the rotor being rotatable together with said vane member upon rotation of the vane member. A rotational axis of the central shaft is offset from a rotational axis of the rotor and a point of action of the vane member is offset from the rotational axis of the central shaft by the eccentric element on the central shaft. The rotor encloses radially the eccentric element of the central shaft.
