Abstract (en)

[origin: EP0822333A2] A rotor (5) is non-rotatably arranged on the shaft (3) in the housing (2) and has external teeth (6). Surrounding the rotor is a rotor ring (7) with inner teeth (8), working in conjunction with the outer teeth of the rotor. The rotor and the rotor ring are fitted between lateral guide surfaces of side guide parts (12,13). Between the teeth of the rotor and the rotor ring work chambers are formed, which in opposing zones form feed-in chambers (29) and feed-out chambers (31). The chambers in rotation operation correspond with control apertures (32a,32b), forming feed-in and discharge apertures connected by conduits with an inlet and an outlet.
