摘要
<p>The gear pump (1) comprises an externally toothed gear (3) and an internally toothed gear (2) that are mounted rotatably. The externally and internally toothed gears are combined together to form a set of teeth and to generate a conveying effect in meshing engagement. The externally toothed gear is mounted on a bearing pin (4). The bearing pin is formed with an inlet (5) through which the fluid is introduced in the interior (8) of the gear pump housing.</p>
