Inner-axial rotary piston machine i.e. screwing machine, for motor vehicle, has rotors axially elongated in its geometries according to rotary ratio and rotatably implemented, where axes of rotors are arranged together in v-shape

摘要

The machine has an inner rotor (1) and an outer rotor (2) axially elongated in its geometries according to an associated rotary ratio and rotatably implemented, where axes of the rotors are arranged together in a v-shape. Sections of the work-geometries lie on concentric spherical surfaces, where the axes lie in a middle point of the spherical surfaces. The inner rotor is stationarily supported in an intended axis intersection, and a sealing gap between the inner and outer rotors is variably adjustable by axial moving of the rotation axes.
