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).
