<p>A method for improving the efficiency of helical screw rotor type compressors working on a gaseous medium of the hydrocarbon or halocarbon compound type, wherein sealing of the clearances is effected by circulating an oil through the compressor, which oil is chosen to fit said gaseous medium in such a way that said oil with said gaseous medium dissolved in said oil has a viscosity which is sufficiently high to maintain a high overall efficiency of said compressor.</p> |
