Abstract
194,842. Lysholm, A. J. R., and Horney, F. Jan. 7, 1922. Spray carburettors.-The suction passage communicates with the space above, the fuel in the float chamber through one or more branch conduits formed in and moving with the throttle valve. A cam shaped member 7 is rotatable in the suction passage-2, 3 to vary the air passage at the fuel nozzle 6 and has formed therein a conduit 12 which communicates with the space in the float chamber 5 through an axial duct 13 and pipe 14. The mouth of the conduit 12 is on the air inlet side of the nozzle 6, the discharge end of which may be at an angle to the air current to affect the discharge. A hinged flap 4 follows the movements of the member 7 and acts as a diffuser. The reduction of pressure in the float chamber may be utilized to cause fuel to flow thereto from a main tank directly and through the intermediary of an auxiliary tank. In a modified construction the throttle valve is in the form of a conical member 24, Fig. 4, displaceable axially in an air passage of sharper angle. Suction is transmitted to the fuel chamber 5 through passages 33 in the throttle member, a passage 30 in the stem thereof and conduit 34 and aperture 35. The fuel nozzle 27 discharges into an air passage 28 which delivers tangentially into an annular recess 29 of the suction passage. Air, to assist in atomizing the fuel, is drawn through a nozzle 36 controlled by a valve 37. Additional air, particularly of use at idling speeds, may be admitted to recess 29 through a needle-valve controlled opening. Fuel to the float chamber is controlled by a valve 46 actuated by a non-buoyant member 43, preferably of aluminium, hinged at 45 and supported by a spring 44. Fuel flows into a cavity in the member whence it overflows into the fuel chamber.
