Abstract
FIELD: gas-turbine engines. SUBSTANCE: while engine is running, air goes from its compressor to supercharge chamber 4 wherefrom it flows on one side through labyrinth gland 6 to gas-air channel 5 and on other side arrives at breather chamber 3 through labyrinth gland 7. Small amount of air entering breather chamber 3 goes to oil space. Main portion of air is expelled from breather chamber 3 through constant-drop valve 9 into the atmosphere. pressure in breather chamber 3 is always lower than in supercharge chamber 4 and is ensured by adjustment of valve 9. EFFECT: reduced amount of high-pressure air ingress in oil space and its discharge through breather which reduces oil consumption.
