Abstract

915,091. Spray carburetters. SWEENEY, F. B. July 8, 1959 [July 8, 1958], No. 23421/59. Class 7(3) Fuel supplied at 78 by a pump passes through a suction-operated pressure regulating valve 86 to a metering valve 54 actuated in accordance with intake air flow, aerating air being bled into the fuel through a passage 174 under the control of a suction operated bleed valve 160. The valve 86 is controlled by a diaphragm 82 subjected to intake pipe suction through a passage 102 and loaded by a spring 100 adjusted by a screw 96. A suction operated accelerating device 110 is connected to the fuel supply passage 62 and a non-return valve 124 prevents backward flow of fuel therefrom to the valve 86. The fuel metering valve 54 is carried by a disc 22 actuated by air flow through the intake passage, the disc entering a small diameter part 12 of the intake passage at low air flows to render it more responsive at such flows. A bimetallic coil 138 in a chamber 128, through which air heated by the exhaust manifold is drawn, actuates a fast-idle lever 144 at cold starting to hold the throttle valve open. The coil 138 also actuates a lever 136 to pull the air bleed valve 160 downwards to close the air bleed passage 174 while the engine is cold; when the engine is warm the coil 138 releases lever 136 and the valve 160 is controlled by suction transmitted through passage 170. The lower end 56 of the fuel metering valve 54 positively cuts off the fuel flow when the engine is inoperative and during overrunning the high intake pipe suction closes valve 86 to cut off the fuel supply. The single fuel nozzle can be replaced by separate nozzles adjacent the intake valves, or the throttle valve can be situated downstream of the fuel nozzle.
