Abstract
An automotive liquid pendulum vane pump includes a pump housing, a rotor ring with circular undercut recesses, a rotor hub with vane slots, and pendulum vanes which connect the rotor ring and the rotor hub. Each vane slot has a substantially plane contact wall slot with a tangential contact nose in an opening region and a diving recess. Each pendulum vane has a circular pendulum head which defines a pendulum hinge which corresponds to a circular undercut recess, a circular pendulum foot which is radially shiftable and pivotable in a vane slot, a vane leg which connects the circular pendulum head and the circular pendulum foot, and a contact path with a contact path surface which contacts the tangential contact nose in a rotational contact sector. A radial inner end of the contact path surface defines an inner tangential projection which temporarily dives into the diving recess.
