Abstract: An electrically driven rotary piston machine which operates as a rotary piston pump or rotary piston compressor wherein the rotary piston machine has a basic housing, which holds an electrical coil and pump head, wherein the pump working space is preferably bounded by a trochoid toothing of the rotors. The pump head which can usually be manufactured relatively economically is embodied as a disposable part and therefore has a quick-action connection with the more complex basic housing.

Abstract: The invention relates to a pump or motor for liquid or gaseous media. The pump or motor has a shaft, which faces a working part, and has a common inclined sliding surface with the working part. The working part which limits the pump working chambers, wobbles in a positionally fixed housing.
Abstract: A rotary piston machine includes a driving part driven by an electric motor, and a driven part that have mutually engaging end-face denticulation for delivering a medium, the driving part and the driven part being housed in a machine housing and connected to the machine housing via respective bottom bearings of the driving/driven parts, creating a unit.
Abstract: A rotary piston machine has a driving part which is driven by an electric motor and a driven part which are geared together and engage one another for the delivery of a medium, the driven part being put under load in the direction of the driving part and the driven part being disposed on a bearing bushing at an appropriate angle to the driven part.
Abstract: In a rotary piston machine with an inner housing and rotors, the axes of the rotors are disposed at an angle to one another in order to equalize manufacturing tolerances and to reduce gap losses of such machines.
Abstract: A rotary piston machine, with a driving part and a driven part, which are geared together, is proposed, for which these parts 17 and 18 run on a common stationary main axle 8.
