Automotive liquid pendulum vane pump

An automotive liquid pendulum vane pump comprising:

• a pump housing;
• a rotor ring configured to be rotatable, the rotor ring comprising a plurality of circular undercut recesses;
• a rotor hub configured to be rotatable and non-shiftable, the rotor hub comprising a plurality of vane slots, each vane slot of the plurality of vane slots being substantially radial and comprising:
• an opening region, and
• a contact wall slot which comprises a tangential contact nose in the opening region of the vane slot and a diving recess, the contact wall slot being configured to be substantially plane;
• and
• a plurality of pendulum vanes configured to mechanically connect the rotor ring and the rotor hub;
• each pendulum vane of the plurality of pendulum vanes comprising:
• a circular pendulum head which defines a pendulum hinge which corresponds to a respective one of the plurality of circular undercut recesses of the rotor ring,
• a circular pendulum foot which is configured to be radially shiftable and pivotable in one of the plurality of vane slots,
• a vane leg which is configured to connect the circular pendulum head and the circular pendulum foot,
• an inner tangential pendulum projection, and
• a contact path comprising a contact path surface which contacts the tangential contact nose in a rotational contact sector, a radial inner end of the contact path surface defining the inner tangential pendulum projection,
• wherein,
• the inner tangential pendulum projection is configured to temporarily dive into the diving recess during an operation of the automotive liquid pendulum vane pump, and
• a mechanical contact between the inner tangential pendulum projection of the pendulum vane and the contact wall slot is always avoided, independent of a rotational position.
