<p>A gerotor pump (10) having a pump body (11) closed by a cover (12). The pump body (11) has a cavity ((CV)) for housing:
- an outer rotor having an outer surface ((SUP1), SUP4)) which slides on the surface of the cavity ((CV)), and an inner surface ((SUP3), (SUP5)) with lobes ((LB1), (LB4)) projecting inwards of the outer rotor; and
- an inner rotor (14, 16) which is fitted to a drive shaft (18) having an axis ((AX)) of rotation, and has lobes ((LB2), (LB3)) which mesh with the lobes ((LB1), (LB4)) of the outer rotor (13, 17). The inner rotor is divided into at least two lobed portions (14, 16) by cutting the inner rotor along a plane ((È)) substantially perpendicular to the axis ((AX)) of rotation.</p> |
