Abstract

958,914. Spray carburetters. SOC. INDUSTRIELLE DE BREVETS ET D'ETUDES. March 22, 1962 [July 17, 1961], No. 11076/62. Heading F1B. In a carburetter having, in addition to the throttle valve 2, an auxiliary throttle 3 operated by the air flow and controlling a fuel metering needle 4 which controls the fuel flow to nozzle 5, all parts of the system connecting the needle 4 to the throttle 3 are subjected to the pressure between the two throttle valves. The needle 4 is connected to the throttle 3 by a plunger 16 and link 18, the pressure in the chamber 17 being that between the throttle valves 2, 3, transmitted through the nozzle 5. The plunger 16 also forms an accelerating pump. The valve 3, pivoted on an eccentric pivot 8, is biased towards the closed position of a counterweight 9 and spring 10. Aerating air may be admitted to the fuel through passage 19. Specification 958,915 is referred to.
