Lubrication 16 - Rotor pump
The rotary-type-pump is built up as a very compact, simple cylinder with two rotary parts that sucks in lubricating fluids and pass them on under pressure.
|The rotor pump is also called Eaton pump.|
A small internal rotor with a few star-shaped teeth, meshes in with an external rotor which has a gap in the gear-teeth, so that in the course of one rotation, liquid is transported from one gap in the external rotor to the other. On one side of the cylinder shaped housing the respective openings provide for the constant influx on one side and for the output on the other side. The teeth of the rotor are so formed, that without having contact, there is no distance between them, thus preventing the back-flow of the oil. The rotary-type-pump transports evenly and can generate moderate pressures. 05/11
