Internal-shaft rotary-piston compressor

Реферат: An internal-shaft rotary-piston compressor contains an inner rotor (18) which is arranged eccentrically with respect to an outer rotor (20, 22) and meshes therewith. A rotary movement initiated at one rotor is transmitted to the other rotor by means of rolling elements (30) which separate chambers from one another, whose volume is changeable during rotation. This rotary-piston compressor is to be improved, with little cost in terms of construction, in such a way that, while the material can be freely chosen, reliable sealing of the chambers is ensured. It is proposed for the rolling elements (30) each to be supported on one side by means of a pin (stud) (32) in the outer rotor (20, 22), which in turn is supported on one side in the casing (2) by means of a rolling-element bearing (24). Said rolling-element bearing (24) is arranged in a radial plane which is at a distance from the inner rotor (18), and/or it has a smaller external diameter than the outer rotor (20). <IMAGE>
