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.
