Abstract
677,812. Spray-carburetters. SOC. D'APPAREILS DE CONTROLE ET D'EQUIPMENT DES MOTEURS S.A.C.E.M. Sept. 30, 1949 [Dec. 22, 1948], No. 24189/49. Class 7(iii) [Also in Group XXXI] A fuel tank and auxiliary engine are arranged on a bicycle so that, when the bicycle is supported with the front wheel above the rear wheel, the filler opening of the tank is above the level of the fuel in the filled tank, and either the parts of the engine which are normally fed with fuel when the engine is running are above the level or, if such parts are below the level, the end at the tank of the feed pipe connecting the tank to the parts is above the level so that the fuel cannot escape. The invention is concerned with preventing fuel leakage when the bicycle is stored in a vertical position. As shown in Figs. 1 and la the the engine 3 is disposed below the carburetter which is disposed forwardly and below the fuel tank 4. fuel normally passing through a pipe 6 to the constant level chamber 5 of the carburetter and thence into the inlet manifold. The constant level chamber 5 is also connected to the fuel tank by a pipe 10, the end of which is disposed above the level N of the fuel in the filled tank when the bicycle is in its normal position. On the bicycle being arranged vertically for storing purposes the fuel takes the level N' in the tank and the fuel in the carburetter and pipes 6, 10 return by gravity to the tank 4, the filler opening 12 of which is so arranged to be above the level N<SP>1</SP>. In a modification, Fig. 2A, the carburetter is arranged behind and below the tank and the constant level chamber 5 is connected to the tank by the pipe 10 having an auxiliary chamber 9 so that on the level in the fuel tank becoming N' the chamber 9 is filled by gravity by fuel in the constant level chamber 5 and the pipes 6, 10. In a further modification, Fig. 3, and 3A, the fuel tank 4 is below the chamber 5 and fuel from the tank is pumped to the chamber 5 by a pump 7, fuel overflowing from the chamber 5 into the chamber 9 which is connected to atmosphere by a pipe 13. On the fuel in the tank taking the level N', the chamber 9 is filled with fuel from the chamber 5 and the pipes 6, 10.
