ROTARY COMPRESSOR PROVIDED WITH AT LEAST ONE SIDE CHANNEL

摘要

The invention relates to a rotary compressor that includes a disc-shaped rotor having a radius R, supporting on the periphery thereof at least one first series of non-planar blades intended for accelerating the fluid to be compressed between an intake and an outlet, a casing defining on the outside at least one generally toroidal channel that is peripheral to the rotor, said at least one channel being coaxial, arranged at the radial end of said rotor and containing said blades, a static and annular core being arranged inside said at least one toroidal channel such as to define a free section A with said casing. According to the invention, the arrangements and respective shapes of the rotor, the at least one peripheral channel and said at least one series of blades are such that the ratio A/R2 is between 6% and 16%.

1. Rotary compressor comprising a disc-shaped rotor having a radius R and supporting on the periphery thereof at least one first series of non-planar blades intended for accelerating the fluid to be compressed between an intake and an outlet, a casing defining on the outside at least one generally toroidal channel that is peripheral to the rotor, said at least one channel being coaxial, arranged at the radial end of said rotor and housing said blades, a static and annular core being arranged inside of said at least one toroidal channel in such a way as to define with said casing a free cross section A characterised in that the dispositions and respective forms of the rotor, of at least one peripheral channel and of said at least one first series of blades are such that the ratio A/R2 is between 6% and 16% and in that it comprises a third series of blades arranged in the radial extension of said rotor and in a given specific channel.
