Automotive pendulum-slider pump

An automotive pendulum-slider pump for providing a pressurized lubricant, the automotive pendulum-slider pump comprising:

• a rotor housing which is non-rotatable;
• a rotor ring which is configured to rotate within the rotor housing and to enclose a pumping chamber which comprises a suction opening, a discharge opening, and an automatically switching pressure adaption valve;
• a rotor hub which is connected with the rotor ring so as to co-rotate therewith;
• and
• a plurality of pendulum vanes which are arranged over a circumference of the rotor ring, each of the plurality of pendulum vanes being pivotably hinged via a separate pendulum hinge at the rotor ring, the plurality of pendulum vanes being configured to fluidically separate the pumping chamber into a plurality of pumping compartments,
• wherein,
• the automatically switching pressure adaption valve of the pumping chamber is configured to pre-open a fluidic connection between at least one of the plurality of pumping compartments and the discharge opening immediately before the at least one of the plurality of pumping compartments has arrived at the discharge opening.
