A gerotor. (Image does not show intake or exhaust ports.)A gerotor
A gerotor/dʒəˈroʊtər/ is a positive displacement pump. The name gerotor is derived from "generated rotor." A gerotor unit consists of an inner and an outer rotor. The inner rotor has n teeth, while the outer rotor has n + 1 teeth, with n defined as a natural number greater than or equal to 2. The axis of the inner rotor is offset from the axis of the outer rotor and both rotors rotate on their respective axes. The geometry of the two rotors partitions the volume between them into n different dynamically-changing volumes. During the assembly's rotation cycle, each of these volumes changes continuously, so any given volume first increases, and then decreases. An increase creates a vacuum. This vacuum creates suction, and hence, this part of the cycle is where the inlet is located. As a volume decreases, compression occurs. During this compression period, fluids can be pumped or, if they are gaseous fluids, compressed.
Gerotor pumps are generally designed using a trochoidal inner rotor and an outer rotor formed by a circle with intersecting circular arcs.[1]
A gerotor can also function as a pistonless rotary engine. High-pressure gas enters the intake and pushes against the inner and outer rotors, causing both to rotate as the volume between the inner and outer rotor increases. During the compression period, the exhaust is pumped out.
