Abstract
A pendulum slider pump may include an inner rotor connected via a plurality of pendulums to an outer rotor. The pendulums may be mounted on the outer rotor in an articulated manner, and the pendulums may respectively include a pendulum foot guiding in an associated radial groove arranged in the inner rotor. The radial grooves may each include a groove base and two circumferentially spaced groove walls. The outer rotor, the inner rotor and two pendulums adjacent in a circumferential direction may each delimit a chamber. Each pendulum foot together with the associated groove walls and the groove base may delimit a pendulum foot space. At least one pendulum foot space may be connected to the associated chamber via at least one communication channel. The at least one communication channel may open into the pendulum foot space in a region of the groove base.
