Abstract

428,301. Spray carburetters. MANNERS, W. H., and CHAPMAN, W. R., 42, Main Street, Sparkbrook, Birmingham. Nov. 20, 1933, No. 32227. [Class 7 (iii)] In a carburetter in which interconnected valves control an air inlet and a mixture outlet, disposed at opposite ends of a body portion, and a variable fuel nozzle between them, the air inlet and mixture outlet are disposed at right angles to the flow of mixture through the body and their valves move longitudinally therein or thereon. A barrel throttle valve 13 and a sliding air valve 6 adjustably connected together by rods 22 control respectively the outlet of mixture and inlet of air to a cylindrical casing 1 having diametrically across it a fuel nozzle 32 provided with a discharge orifice 36. A rotatable sleeve 7 within the casing determines the maximum size of the air inlet port 4, and may close it for starting. One side of the port 4 is curved to ensure a proper air-fuel ratio at all throttle openings. The throttle valve 13 works in a sleeve 25 having oppositely arranged openings 29, 30 governing the maximum throttle opening and the admission of secondary air through a port 31 in the casing 1. The air valve 6 is coupled to a plate 43 mounted on the rods 22 and provided with holes 47 for the reception of two pins 42. These pins engage levers 40, 38 mounted respectively on a sleeve 37 screwed on the top of the nozzle tube 32 and an outer sleeve 39 screwed, with an opposite thread, on the sleeve 37. The sleeve 39 supports the fuel needle valve which is lifted by the operation of the threaded sleeves when the levers 38, 40 are rotated by movement of the plate 43. An eccentric may be associated with the air inlet sleeve 7 to displace the plate 43 and provide additional fuel at starting.
