Abstract
620,124. Spray carburetters. SOC. D'ETUDES DE CARBURATION POUR L'AUTOMOBILE ET L'AVIATION S.E.C.A.A. Aug. 14, 1945, No. 20884. Convention date, Oct. 15, 1943. [Class 7 (iii)] In a carburetter having the fuel supply to the jet 8 controlled according to atmospheric pressure and intake manifold pressure by two capsules 15, 17 controlling needle valves 13, 14, the mixture strength is also controlled according to the temperature of the intake air by a device 20 separate from the capsules. The capsule 17 is enclosed in a chamber 18 subject to pressure at the outlet of compressor 3 through the pipe 19, and the capsule 15 is subject to changes in atmospheric pressure through the pipe 16 leading to a chamber 27 having a calibrated orifice 28 and connected by a pipe 26 to the throat of the Venturi 6. A bi-metallic spring 20 carrying a needle 23 controls the size of aperture 25 in the tube 26, an increase in the temperature of the intake air increasing the aperture 25 to lower the pressure in the chamber 10, thus decreasing the fuel supply. In a modification, the capsule 15 is enclosed in a chamber connected to the intake 5 so that changes of pressure in the chamber 10 due to the temperature control do not effect the capsule. The bi-metallic spring may be replaced by. a capsule filled with liquid. Specification 579,334 is referred to.
