Abstract

An automotive pendulum-slider pump for providing a pressurized lubricant. The automotive pendulum-slider pump includes a non-rotatable rotor housing, a rotor ring which rotates within the rotor housing and which encloses a pumping chamber which includes a suction opening, a discharge opening, and an automatically switching pressure adaption valve, a rotor hub which is connected with the rotor ring to co-rotate therewith, and pendulum vanes which are arranged over a circumference of the rotor ring. The pendulum vanes are pivotably hinged via a respective pendulum hinge at the rotor ring. The pendulum vanes fluidically separate the pumping chamber into pumping compartments. The automatically switching pressure adaption valve of the pumping chamber pre-opens a fluidic connection between at least one of the pumping compartments and the discharge opening immediately before the at least one of the pumping compartments has arrived at the discharge opening.
