Filed: 1992-12-30
Granted: 1995-04-30
Abstract: FIELD: gas-turbine engineering. SUBSTANCE: system has fuel pipe line 1, air pipe line 2, passages 3 and 4 of the first and second manifolds connected with respective nozzle passages of the combustion chamber, autonomous source 5 of compressed air connected with pipe line 2, solenoid valve 6, valves 7 and 8, distributing valve 9, and blocking unit 13 constructed as servo-piston 14 having rod 15. Gate 16 is mounted at the free end of the rod. Gate 16 and seat 17 define a valving member. One end of the distributing valve is connected with pipe line 1, and other one is connected with passage 3 of the first manifold through passage 10, valve 7, and opening 11 made in the bushing of the valve and with valve 8 through passage 12. Spring space 18 of servo-piston 14 is connected with solenoid valve 6 to which a command is fed in driving the engine up to speed. When valve 6 is actuated, space 18 is coupled with the drain, under-piston space 19 being connected with passage 20 of high pressure. Under the action of pressure drop, the servo-piston is displaced so that gate 16 moves away from seat 17 and groove 21 of rod 15 is disconnected form passage 4 which is coupled with autonomous source 15 of compressed air through groove 22 of rod 15, seat 17, and passage 2. Air begins to enter the nozzles through passage 4 of the second manifold, fuel being fed through passage 3 of the first manifold. This will occur until firing of the combustion chamber will be completed. After firing, one picks command off valve 6, and servo-piston 14 moves back to the initial position. As the result, gate 16 seats on seat 17 and supplying of air to passage 4 stops, passage 4 being connected with valve 8 through groove 21. By this time, valve 8 has been opened and fuel enters passage 4 through it. When engine stops operation, and after draining fuel from valves 3 and 4 to the drain through drain valve 31, a command is fed to valve 6 to connect space 18 with the drain. Servo-piston 14 is shifted so that gate 16 moves away from seat 17. Compressed air enters pipe line 24 through passage 2, seat 17, groove 22 and next passage 4 and simultaneously to passage 3 through passage 26, nozzle 28 of valve 25, and opening 11 made in passage 3. As the result, the nozzles of the combustion chamber is blew through by air. EFFECT: improved design. 3 cl, 1 dwg
