Abstract
Provided is a gas turbine engine including a main passage through which compressed air extracted from a compressor is guided to a bearing; and an oil supply device that supplies oil to the main passage. The oil supply device includes a pressure reducer in the main passage; an oil tank a divider that is movable and divides an internal space of the container into an oil chamber storing the oil and an air chamber; an extruder including a cylinder and a piston that divides an internal space of the cylinder into a first chamber and a second chamber; a switching mechanism that switches between a first state where the first chamber communicates with a low-pressure space whose pressure is lower than pressure in the air chamber and a second state where the first chamber communicates with a high-pressure space whose pressure is higher than pressure in the downstream passage.
