Abstract

536,549. Spray carburetters. PICKERING, C. G. March 18, 1940, No. 4995. [Class 7 (iii)] In a carburetter as described in Specification 504,372, in which a heated mixture of fuel and primary air is admitted to a secondary air stream, and means are provided for obtaining a richer mixture and a larger inlet for the secondary air as the main throttle is opened, the inlet for admitting the heated mixture of fuel and primary air to the induction pipe is located on the engine side of the main throttle. Primary air admitted at 2 from the intake 3 flows past fuel nozzle apertures 31, 32, the mixture issuing by a pipe 10 leading to a heater, such as a jacket surrounding the exhaust manifold, or an electric heater, and returning by a pipe 11 and ports 13, 5a to the choke tube 5, where it mixes with secondary air from the intake 3. The openings 5a are arranged on the engine side of an eccentricallymounted throttle 6, which is actuated by suction and also by an arm 14 connected to the accelerator pedal. The spindle 7 of the throttle carries an arm 35 which moves, subject to the action of a spring 38, between stops 36, 37 on a cam 15, which in turn carries abutments 33, 34 co-operating with the arm 14 loose on the spindle 7. The cam 15, as the throttle is opened, operates an arm 16 to rotate the fuel nozzle 17 and alter the position of the orifices 31, 32 so as to give a richer mixture. The nozzle is surrounded by a sleeve formed with segments 26, 27, so that rotation of the sleeve by an arm 30 varies the effect of the primary air on the nozzle. Fluttering of the throttle valve is prevented by a dashpot 40 connected thereto by a rod 42 and arm 43. The main throttle may be arranged in the air intake 3 above the passage 2, the throttle 6 being then actuated only by suction.
