Abstract

The invention relates to a rotary piston machine which can function as a pump, compressor or motor. A cycloid power component and a correspondingly formed blocking component are in mutual engagement in said machine. The difference in the number of teeth between both components is one. The volume of the working chambers (16) thus created attains a maximum and a minimum level at each rotation owing to the synchronous rotation of said power component and blocking component.
