FIELD: machine building.
SUBSTANCE: invention relates to an oil nozzle for a gas turbine engine, comprising housing (16) having circulating tube (18) for pressurized fluid medium. Nozzle case (16) comprises first part (24) and second part (26), between which there is an elastically deformable membrane (52) configured to deform between a closed position, in which it prevents circulation of fluid medium in tube (18), and position, in which it does not prevent circulation of fluid medium in tube (18). Second part (26) contains support facility (46) made with the possibility of application of force to membrane (52) in the direction opposite to the direction of circulation of the fluid medium, so that to ensure preliminary loading of membrane (46) in the closed position.
EFFECT: invention helps to limit, by blocking oil circulation, oil losses in oil pipeline, which occur under action of gravitation at stop of gas turbine engine; as well as providing pressure in the circuit is considerably simplified, and lubricating oil can be quickly supplied to various mechanical elements, which need it.
