Gerotor pump

Abstract

A gerotor pump has an outer, rotatably mounted gerotor having at least one hollow tooth which is closed by a lateral plate and/or a cap, the interior of which has a fluid connection radially inwards. The fluid connection may be formed as a cut-out, slot, opening or bore. Further, the fluid connection may extend at an angle to a radial direction of the outer gerotor and/or outside of the middle of the tooth at least in part.
