Definitions
- This invention relates to gerotor pumps which, as well known, comprise a male lobed rotor with n lobes and a female lobed rotor or annulus with n+1 lobes in which the male rotor is located and meshed. Both are contained in a pump body. This creates a series of chambers between the two rotors, and when the two rotors turn about their parallel axes the chambers vary in volume between a minimum and a maximum on the inlet side thus inducing fluid flow into the chambers through an inlet port and vice versa on the outlet side thus expelling fluid from the pump through an outlet port.
- the annulus may be held axially in the body 46 by means of a washer 50 and a circlip 52 as illustrated in the lower half of Figure 2; alternatively a more massive retaining ring 54 may be pressed into the cylindrical cavity which receives the gerotor set as an interference fit therein, and used to retain the parts in the required axial positions.
