Abstract: 4567. Wishart, T. G. Feb. 22. Spray carburettors.-In a carburettor having a choke - tube axially movable relatively to the spraying-member and a needle fuel-valve movable axially to an extent proportionate to the movement of the choke-tube, the choke tube 7 is actuated by the arm 22 of a bell-crank lever, and the fuel-valve 13 is actuated by the arm 21 of the lever, the ratio of the movement of the choke-tube to that of the fuel-valve being variable. The fuel-valve is pressed upwards by a spring 14a and is adapted to be depressed by a crank-arm 15 mounted on a shaft 16, on the other end of which is a crankarm 18. On the shaft 16 is pivoted a slotted arm 19 adjustably carrying a roller 20 engaged by the arm 21 of the bell-crank lever, and also carrying an adjustable screw 19 engaging the lever 18 ; by adjusting the position of the roller in the slotted arm, the ratio of the movement of the choke-tube to that of the fuel-valve is varied. The fuelspraying member consists of two parts 2 , 2 with a central fuel-passage 3 and radial passages 4 leading to the jets 5 ; the fuel-valve has flutes 14 at its lower end.
