Abstract

A liquid ring compressor (10), wherein the gas distribution is obtained by means of a central stator (11), which has a frusto conical shape, comprising at least a rotor (12A, 12B), provided with a plurality of radial blades (14) mounted on a shaft (13), which is concentric with the longitudinal axis (25) of the compressor (10); the configuration of the blade (14) is such that performances, substantially higher than the performances of the traditional compressors, can be obtained at relatively high working pressures; finally, in order to obtain higher working pressures, two rotors (12A, 12B) of the above described type are positioned one after the other and a hydraulic barrage is created between first and second stage, in order to oppose the natural gas flow from the second stage rotor (12B), at high pressure, to the first stage rotor (12A), at a lower pressure. <IMAGE>
