<p>622,904. Liquid fuel supply to burners. POWER JETS, Ltd., and FEILDEN, G. B. R. Oct. 30, 1941, No. 13978. [Class 75(i)] [Also in Groups XXVI and XXIX] Fuel for the burners of a gas-turbine, is supplied through a valve 24a which opens when the pressure of fuel delivery has risen sufficiently. When the valve 24a is shut, the port 22 leading to the burners is opened, by fluted passages 24c on the surface of the sleeve 24d, to a waste pipe 29. When the valve 24a is open, the line to waste is closed by the head 24 of the sleeve entering the bore 23 and by the tail of the sleeve seating upon a ring 27. One such valve may control the supply to the starting burners and another, operating at a high pressure may control the remaining burners. Specifications 577,971 and 588,083, [both in Group XXVI] are referred to.</p> |
