WORKING MEDIUM CARRY-OVER SYSTEM FOR SWIVEL NOZZLE OF JET TURBINE ENGINE Russian patent published in 2012 - IPC F02K1/78 

FIELD: engines and pumps.

SUBSTANCE: working medium carry-over system for all-aspect swivel nozzle of jet turbine engine includes two hollow levers and two hollow hinge assemblies rigidly fixed by means of eye lugs enveloping hollow sleeves, one is on fixed housing of engine nozzle, and the other one is on its movable housing. One end of each hollow lever is connected to the corresponding hollow hinge assembly, and their opposite ends are connected to each other by means of additional hollow hinge with hollow cross piece connecting the cavities of levers. One lever is installed in hinges with possibility of being turned in radial guide in the plane perpendicular to horizontal rotation axis of nozzle, and the other one is installed in two mutually perpendicular planes. Attachment of movable and fixed housings is made so that their connection point can be moved along spherical surface in any direction relative to fixed nozzle housing.

EFFECT: invention allows improving reliability of working medium carry-over system from engine to all-aspect jet nozzle.
