MAHLE pendulum-slider oil pump

3D Animation of the controlled MAHLE pendulum-slider oil pump which supplies lubricating oil to the engine as and when needed. Overall, this enables a CO2 reduction potential of up to two percent in the New European Driving Cycle (NEDC) and three percent under actual driving conditions.
With an overall efficiency of 65 to 70 percent and a volumetric efficiency of more than 92 percent, the pendulum-slider oil pump converts an extremely high proportion of the drive energy into delivery output. Thus, compared with other pump types such as the external-gear pump and the vane pump, it operates with a considerably greater efficiency. This is made possible by the internal structure of the pump: Rather than using sliding gaskets to seal off individual pump cells, this pump uses pendulums supported in the outer rotor of the pump, which enables a rolling motion without sliding in grooves on the internal rotor.
