Vane pumps and gerotor pumps too are often available as multi-pumps.

The newest gerotor pump based system has computer regulated output for more versatility and no oscillation.

In combination with the Gerotor pump they are able to send the power to the one wheel with traction even if the other three wheels are spinning.

Gerotor pumps are generally designed using a trochoidal inner rotor and an outer rotor formed by a circle with intersecting circular arcs.

This style limited-slip differential works by using a gerotor pump to hydraulically compress a clutch to transfer torque to the wheel that is rotating the slowest.

The gerotor pump uses the differential carrier or cage to drive the outer rotor of the pump and one axle shaft to drive the inner rotor.

An electronic limited-slip differential will typically have a planetary or bevel gear set similar to that of an open differential and a clutch pack similar to that in a torque sensitive or gerotor pump based differential.
