ABSTRACT:
The radial cross sections of the three engagement parts of the external rr of an internal axis single-rotation machine are defined by outer and inner circular arcs. The shape of the internal rotor, having two engagement parts, is kinematically precisely adapted to the external rotor. In order that the internal rotor can be easily manufactured with high shape accuracy, that the machine be given a good volumetric efficiency, and that a good seal be obtained between the rotors, even in the case of high rotational speeds, the center of the circle containing the arcs of the inner faces of the engagement parts of the external rotor has a spacing from the rotational axis of the external rotor of at least approximately 9 times the amount of the eccentricity between the two rotors, and the radius of the external rotor inner faces is about to 7 to 7.5 times this eccentricity.
