POSITIVE-DISPLACEMENT MACHINE DESIGN (VARIANTS)

摘要

In the first variant, the device comprises a stator and a rotor eccentrically mounted in the stator. A planetary train consists of large and small gear wheels. The large gear wheel of the planetary train is fixedly arranged from outside of the small gear wheel and is engaged therewith in such a way that the small gear is enabled to run around it. The stator is coupled with the large gear wheel and the rotor is coupled with the small gear wheel. The equations describing the outlines of the stator and rotor are also disclosed.
