Abstract

The apparatus for the oil supply to a screw compressor (3) comprises a closed circuit for the oil. In this circuit, the delivery line (16) of the compressor (3) is connected to an oil separator (4) in which refrigerant dissolves in the oil. The resulting oil/refrigerant solution is divided into two sub-flows, one sub-flow being cooled in a cooler (8) and fed to the bearings and to the shaft seal (12) of the compressor (3). The second uncooled sub-flow is injected into the compression chamber of the compressor (3) via a line (14). To control the outlet temperature of the refrigerant/oil mixture leaving the compressor (3), a temperature sensor (17) feeds a signal to a final control element (21) which so controls a three-way valve (20) connected to receive either of the sub-flows through lines (19) and (14) that an appropriate quantity of the cooled oil/refrigerant solution is injected into the compression chamber in dependence on the outlet temperature of the refrigerant/oil mixture. By means of these steps, the viscosity of the oil/refrigerant solution injected into the bearings of the compressor (3) does not fall below a required value. <IMAGE>
