DEVICE TO FEED FUEL INTO TURBO MACHINE COMBUSTION CHAMBER Russian patent published in 2010 - IPC F23R3/60 F23R3/28 F02C7/20 

FIELD: engines and pumps.

SUBSTANCE: proposed device serves to feed fuel in, for example aircraft turbojet or turbofan engine. It consists of fuel feed circular guide element that passes around combustion chamber outer cylindrical casing and is attached to fuel feed appliances. It comprises also multiple injectors attached to the casing and open toward combustion chamber. Said injectors communicate with fuel feed guide element via bent fuel feed channels and are attached thereto with the help of guide element supports. The latter comprise easily deformable appliances to allow the casing to thermally expand radially relative to circular guide element and to make a hard support for aforesaid circular guide element. Said deformable appliances can comprise one pull spring, two pull springs, two elastically deformable metal rods or two plates, rivets, compression spring and screw, metal damper, laminate support made up of a set of metal taper washers or plates, or a set of elastomer washers.

EFFECT: compensation of casing thermal expansion.
