<p>1,116,549. Spray carburetters. GENERAL MOTORS CORPORATION. July 28, 1966 [Sept. 16, 1965j, No. 33880/66. Heading F1B. [Also in Division G3] The fuel delivery from a nozzle 50 is controlled by a fluid amplifier arrangement 18 comprising several fluid amplifiers 24 ... 28. Fuel is supplied by pump 22 to chamber 20 supplying the amplifier inlets 24 ... 28, each amplifier having a pair of outlets 30, 32, 34, 36 and 38, 40, one set of outlets 30, 35, 38 being interconnected and leading back to tank 42 whilst the other set of outlets 37, 36, 40, are connected to nozzle 50. At low air flow the flow from inlet 24 is split between outlets 30, 32 whilst that from inlet 26, 28, discharges solely into outlets 34, 38. As the suction at the Venturi throat 16 increases, more fuel from inlet 34 is diverted into outlet 32 and when all the fuel is discharging into outlet 32 fuel from inlet 26 begins to be diverted into outlet 36. At highest suction the inlet 28 becomes operative to deliver into outlet 40.</p> |
