Patent GB-135858-A (GB)
IPC: F02D9/00
Abstract: 135,858. Sturtevant Co., B. F., (Assignees of Morton, H. E.). Nov. 27, 1918, [Convention date]. Spray carburettors.-In a carburetting system particularly applicable to aeroplane engines, the pressure of mixture supplied to the engine is maintained independently of alterations in atmospheric conditions by means of a compressor driven from the engine by automatically-controlled variable-speed transmission devices. Air is supplied to the carburettor 9 and to the fuel-supply tank 79 by a high-speed centrifugal fan 23 driven by toothed gearing 36, 31 from a countershaft 29 which is driven by a belt 32 from the engine crank-shaft. The belt 32 does not drive until it is tightened by the action of a jockey pulley 37, which is pressed against the belt to tighten it as the atmospheric pressure falls. For this purpose the pulley 37 is carried by a plunger 41 mounted in a cylinder 45 and moved against springs 46 by means of oil from the lubricating-pump 10. The pressure of oil behind the plunger head 49 and consequently the speed of the fan is controlled by a partly exhausted bellows 60 which regulates the position of a valve 70 so as to reduce the outlet of oil as the atmospheric pressure falls. The cylinder 56 containing the bellows 60 is in communication bv means of a pipe 75 with the delivery pipe 20 from the centrifugal fan. Hand control of the valve 70 is provided by a T-shaped lever 81 with suitable connexions. The fan blades 24 and webs 25 are formed in one with the fan shaft 26, and a silencer 36 is fitted to the air intake. For the purpose of maintaining the mixture supply at constant temperature, a jacket 113 surrounding the induction pipe is connected to the cylinder jackets by pipes 110, 112, 114. At higher levels as the fan heats the air supply, a cooling action is provided by the operation of a piston-valve (not shown) in a casing 111. This valve is actuated by the pressure of the lubricating oil to close the communication between pipes 110, 112 and open communication between pipes 112, 116, whereupon the water is forced through a radiator 120 by a small pump 118 driven by the propellor blast and so acts to cool the induction pipe.
