Abstract

The invention relates to a gear pump for delivering a fluid, comprising a rotatably mounted, outside-toothed gear wheel and an inside-toothed annular gear, which together form a toothing arrangement and are in meshing engagement to generate a delivery effect, wherein a respective profiled toothing section of the outside-toothed gear wheel and of the inside-toothed annular gear has a conical design.
