Abstract

158,336. Weiland, A. Oct. 30, 1919. Spray carburettors.-Liquid fuel is drawn from a low-level tank into a reservoir 10 by the suction in the intake 12, and means are provided to prevent a gravity-flow from the reservoir when the. suction in the intake is interrupted. The fuel flows from the reservoir 10 through a float-operated valve 25 to a chamber 16 which feeds a chamber 21 connected by a pipe 22 to the jet-chambers 23. The chamber 21 is connected to atmosphere by a pipe 33, so that, when the liquid level in the chamber 21 falls below this pipe, air enters the chamber 16 and allows fuel to flow into the chamber 21. Air, which may be heated by the exhaust, enters the chamber 11 and passes through ports 41. 42 in a rotatable throttle 36 into the intake 12. The fuel passes from the chamber 23 through a port 24 controlled by a needle 46. The needle 46 is carried by a tube 45 attached to a piston in a chamber 50. The upper side of the piston is open to atmosphere and the underside is exposed to the vacuum in the intake 12 through ports 54, 55, so that the intake pressure controls the position of the needle 46 and the supply of fuel through the port 24. When the throttle 36 is closed air flows from the port 41 down through a passage 44 and serves as an auxiliary priming means. The pipe 60 connecting the chamber 10 to the intake 12 opens into a recess 63 into which fuel overflows when the engine stops and seals the pipe 60, thereby preventing the atmospheric pressure in the intake from reaching the reservoir 10.
