FIELD: engines and pumps.
SUBSTANCE: combustion chamber of gas turbine engine includes chamber bottom in which there is at least one through hole or essentially annular hole, injection system connected to the hole, and deflector installed in the hole on read side of chamber bottom by means of annular sleeve. Injection system includes clamping ring installed on front side of chamber bottom, which is fixed on the sleeve, and restricting together with the latter an annular slot open from axis of hole of the chamber bottom; and annular bowl installed in the hole of chamber bottom. Bowl consists at least of two separate parts. At least one first part forms annular flange having the possibility of radial sliding movement in the slot formed with clamping ring and sleeve. The second part forms shoulder of bowl, which is equipped with annular shoulder located parallel to chamber bottom on its rear side. At that, the above first and second parts of the bowl are attached to each other by means of clutch coupling.
EFFECT: providing thermal protection at misalignment of injection system relative to combustion chamber bottom and in order to avoid penetration of component parts of combustion chamber inside it in case of failure of soldering or weld.
