A contour of the external teeth (10) on the gerotor inner element (1) is defined from a tooth tip (11) continuously via the tooth flanks (13) as far as a transition radius (14) to a tooth gap or a tooth root (12) substantially by way of a curve of a single ellipse; wherein the main axis of the ellipse is oriented radially with respect to the gerotor inner element (1), and the centre point of the ellipse fixes a radius (Rmin) on the gerotor inner element (1), which radius (Rmin) corresponds to the maximum engagement depth of the gerotor outer element (2) between the external teeth (10) at the meshing engagement.

The invention relates to a vane pump for conveying liquids, in particular viscous oils, which vane pump comprises: a rotor (2) having sliding slots (23) in which movable vanes (3) are held and can be countersunk in relation to a rotor radius (r); a pump housing (1) comprising a pump chamber (10), which encloses the rotor (2); and an inlet (5) and an outlet (6), which open into the pump chamber (10) at at least one end face of the rotor (2); radial elevations (21) protruding, with respect to the sliding slots (23), over the circumference of the rotor (2), which elevations form a rotor radius (r) on either side of the vanes (3) that can be countersunk, and radial pockets (20) being recessed, relative to the rotor radius (r), between the radial elevations (21). Within the radial elevations (21), recesses (4) are formed on the at least one end face of the rotor (2) at which the inlet (5) and the outlet (6) open, which recesses provide rotating anticipatory control geometry for reducing pressure spikes in the vane cells.
