Abstract

299,191. Imperial Chemical Industries, Ltd., and Davenport, H. C. Oct. 27, 1927. Spray carburettors.-A straight-through passage 3 is controlled by a piston throttle valve 4 having an axial bore 13 adapted, for about the the first half of its opening movement, to cover a main nozzle 7. This nozzle is fed through a constriction 8 and has in its wall an aperture or apertures 12 adapted to feed an auxiliary nozzle 11 concentric with the nozzle 7 and discharging above the normal fuel level Z - - Z but below the outlet of the main nozzle. The bore 13 communicates with the atmosphere through an aperture 17 regulated by a valve 18. A bye-pass conduit 22 may communicate with the bore 13, and its outlet 21 may be covered when the throttle is fully closed. At first, only the auxiliary nozzle is in action, and the fuel it delivers is aerated by air passing down the main nozzle. When the throttle is raised further and the main nozzle is in action, air passes down the auxiliary nozzle to aerate the fuel.
