FIELD: power engineering.
SUBSTANCE: screw-rotor machine comprises two screw rotors 102 and a vessel 101, having an inlet hole 114 and an outlet hole 113. Rotors 102 are equipped with axial journals 104, installed in bearings 106. The bearing 106 is lubricated with oil and is installed in a bearing chamber 105, which communicates with a working space 115 of the machine via a seal 107 of the gap. The bearing chamber 105 also communicates with an oil supply pipeline 111 and a drainage pipeline 108, connected to the pressure, which is lower than the lowest pressure in the working space 115, when it is open towards the outlet hole 113.
EFFECT: provision of energy conversion at relatively low levels of capacity with improved efficiency, higher reliability.
