FIELD: engines and pumps.SUBSTANCE: guide device for an element located in the hole of the combustion chamber wall of a gas-turbine engine includes coaxial ring and sleeve, which are installed inside each other. The ring is meant for passage of the above element through it in axial direction and includes an annular projection guided in transverse direction in the sleeve annular groove fixed on the hole edge of the combustion chamber wall. The sleeve includes two coaxial annular parts attached to each other and forming a guide annular groove between each other, which is intended for the ring projection. The ring of the guide device has the possibility of being moved in transverse direction. One of two parts of the sleeve represents a washer having an external peripheral edge having zones connected to the other part of the sleeve and zones that are not connected to the other part of the sleeve. The disconnected zones are located on one line along the axis parallel to the ring movement direction, and the connected zones are uniformly distributed relative to the sleeve axis. The other part of the sleeve includes a continuous cylindrical projection about the ring external projection; disconnected zones of the peripheral edge are not borne against the above projection. The other invention of the group refers to a combustion chamber of a gas-turbine engine, which contains a spark plug or a fuel injector, which are installed in the above guide device. One more invention refers to a gas-turbine engine containing the above combustion chamber.EFFECT: inventions allow simplifying assembly of a guide device and reducing its dimensions.9 cl, 4 dwg |
