Abstract (en)
[origin: EP1074740A1] The machine has a displacement part (1) working with a centrally supported shaft (2). The displacement part has a first rigid casing part (4) with a first inner toothing, which co-operates with a rotatable eccentric rotary piston having an outer toothing with one more tooth than the first inner toothing. The rotary piston has a second inner toothing (8), which meshes with a second outer toothing (9) at the shaft, where the second inner toothing has two more teeth than the second outer toothing. Shaft bearings (10,11) are arranged directly on the left and right of the displacement part. A disc-shaped turning valve and an eccentric inner gear (12) are provided for the drive, where the inner gear guides the rotary valve in orbit about the machine axis of the eccentric movement.
