Abstract

In a method of operating a meshing-screw compressor a substantially incompressible lubricating and sealing fluid e.g. oil, is injected into the rotor chamber. To improve the performance the viscosity of the said fluid is between 0.5 and 15 cSt at a final operating temperature of 60 to 80 DEG C and the ratio of the actual rotational speed to the optimum rotational speed of one screw rotor is between 0.5 and 1.5. The flow-rate of the said fluid is sufficient to prevent this fluid exceeding the said final operating temperature.
