Abstract: Rotary compressor arrangement (100) comprising a body (40) centered at a shaft axis (X) and a cylindrical piston (10) eccentrically arranged with respect to the body (40) such that a chamber is created between them, the arrangement (100) further comprising a satellite element (50) arranged at an offset axis (Y) and orbiting around the shaft axis (X) such that the orbiting of the satellite element (50) entrains in rotation around the shaft axis (X) the cylindrical piston (10) over the body (40), the relative distance between the axis (X, Y) being such that a contact between the body (40) and the cylindrical piston (10) within the chamber is ensured during rotation of the cylindrical piston (10).

Abstract: Rotary compressor arrangement (100) for compressing a fluid comprising a body (40) centered at an axis (X) of a shaft (20) and a cylindrical piston (10) eccentrically arranged with respect to the body (40) such that a compression chamber (110) is created between them; the arrangement (100) further comprising a satellite element (50) arranged at an offset axis (Y) and orbiting around the axis (X), the satellite element (50) contacting the external wall of the cylindrical piston (10) under a certain pressure or force such that the orbiting of the satellite element (50) entrains in rotation around the axis (X) the cylindrical piston (10) over the body (40); wherein the shaft (20) and the body (40) are solidary and static within the compressor arrangement (100); and wherein the shaft (20) comprises at least one inlet port (130) through which a compressible fluid is introduced into the compression chamber (110) for being compressed and/or one outlet port (140) through which the compressed fluid exits the compressor arrangement (100). Cooling/refrigerating system comprising such a rotary compressor arrangement (100).
