A gerotor pump set is shown in Figure 4 having passages 32 extending parallel to the axis of rotation through the female lobed annulus, and similar passages (not shown in the illustration) through the male lobed rotor. These, or either of them, enable flow from the inlet 38 to pass into the working chamber such as 42a either directly at the inlet end, or after flow through those passages and through the transfer passage 43 at the opposite axial end to the inlet, without requiring a transfer passage externally of the annulus. The result is better axial filling of the working chambers, in a particularly compact design.
