Title: Improvements in and relating to fuel feeding systems for internal combustion engines
IPC: F02B1/00
Filed: 1919-11-07
Abstract: 158,667. British Thomson - Houston Co., Ltd., (General Electric Co.). Nov. 7, 1919. Regulating.-The delivery of a fuel pump supplying the carburettor of an internal-combustion engine is controlled so that the fuel pressure is higher than the pressure of the air to be carburetted. As applied to an aeroplane engine in which a fan supplies air under pressure to the carburettors 5 through the air pipe 7, a pipe 31 leads from this pipe to the top 30 of a diaphragm chamber 23. The underside of the diaphragm is subjected to the pressure on the delivery side of the fuel pump 18 by means of a pipe 22. The diaphragm controls a spring-pressed valve 25. When the fuel pressure exceeds the air pressure assisted by the spring 32, the valve 25 lifts and part of the fuel returns to the tank 15 by the bypass pipe 22<1>. Priming at starting is effected by the hand pump 33. Fuel that collects in the air pipe is returned to the tank 15 by means of the pipe 37 and valved chamber 43. The valve is held on its seat by the air pressure acting on the diaphragm 42 and the spring 45, the head of liquid in the pipe 37 having to overcome this pressure before the drain valve is opened. When air at atmospheric pressure is used in the carburettor, the top of the diaphragms are open to the air.
