| 摘要 |
<p>The invention concerns a corrosion proof pump or motor with an inner, outside toothed tooth wheel rotating around a first centre, whereby the inner tooth wheel engages an outer, inside toothed tooth wheel rotating around a second centre which is displaced in relation to the first centre, whereby both the inner and the outer tooth wheels rotate between side plates, and the outer tooth wheel rotates in an outer bearing which is at the same time a distance piece between the side plates. The pump or motor is especially suited for media with a low viscosity, in that the side plates and/or the outer bearing and/or at least one of the tooth wheels consist of a binding material containing reinforcement and/or wear resistance improving and/or friction reducing materials.</p> |
