Abstract (en)
[origin: EP0846861A1] The pump has a stationary housing (1) and an annular ring set (5) with inner rotor (3) and meshing outer rotor (4). The gear ration of the inner rotor and the annular ring set is equal to 1. The bearing (12) of the outer rotor along its outer diameter (13) is inside the adjusting ring (14) of preferably the same width. The adjusting ring moves slip-free with its outer part circle (15) on an inner part circle (16). The difference between the diameters of the two part circles is double the eccentricity (17) of the ring set.
