FIELD: engines and pumps.SUBSTANCE: invention relates to aircraft engine building, namely to an oil system of an aircraft gas-turbine engine. In the known oil system containing an oil tank, an oil filter with a siphon trap and an air bleeding jet nozzle in a loop of the siphon trap, which are installed in an engine oil supply line; with that, the loop of the siphon trap with the air bleeding jet nozzle is located inside the oil tank cavity, and the jet nozzle is interconnected with its free volume, according to the invention, an uprising part of the loop of the siphon trap is formed with the filter oil supply line, and the descending part of the loop is formed with an internal cavity of the oil filter housing.EFFECT: invention provides reduction of a hydraulic resistance in an engine oil supply line and reduction of oil pressure losses in its circuit, as well as reduction of length of the oil supply line, and as a result, weight of the required pipelines. |
