Abstract

158,040. Rzetelski, V. Oct. 18, 1919. Spray carburettors.-Relates to floatless carburettors and consists in the provision and arrangement of main and auxiliary nozzles which operate alternately and automatically according to the position of the throttle valve. The carburettor shown in Fig. 1 comprises a main nozzle 4 disposed across the choke-tube 55 and an auxiliary nozzle 27 communicating with the suc-- tion pipe 2 in the vicinity of the throttle valve 3. Fuel is supplied to the nozzle 27 from a fuel inlet pipe 31 past a suction-actuated valve 21. The valve stem 23 carries a double disk regulator 26 situated as shown relatively to an air inlet 29. Below the regulator is an orifice 28, opening into the suction pipe 2, of larger area than the nozzle 27. When the throttle valve is closed, the engine suction draws in air by the inlets 28, 29 and lifts the regulator 26 and valve stem 23, thereby opening the fuel valve 21. When the throttle valve is opened, the suction at the orifice 28 is greater than at the nozzle 27, on account of its larger area. The air drawn in at the inlet 29 therefore exerts a downward thrust on the regulator, and keeps the fuel valve 21 closed. The mixture is therefore supplied to the engine by the main nozzle 4. The construction of the nozzle 4 is shown in Fig. 8. The nozzle comprises outer and inner perforated tubes 4<1>, 56, the outer tube being enlarged and screw-threaded at the end 4, or otherwise adapted, for insertion across the inlet pipe 1, as shown at Fig. 1. A rod 8 is slidably disposed within the tube 56, and carries at one end the fuel valve 9, the stem 11 of which is of polygonal section and slides in a circular bore 10. A disc 24 is carried by the other end of the rod 8. Suction in the inlet pipe 1 draws air through the open end 25<1> of the nozzle past the disk 24. The rod 8 is thereby displaced and the fuel valve 9 opened. The fuel, which enters through an exchangeable nozzle 32, is atomized by air drawn in through passages 15, 16 and variable nozzles 17, Fig. 1, and mixes with the main air passing through the perforations in the tubes 4', 56, and the air which enters past the disk 24. In modifications, the relative dispositions of the main and auxiliary nozzles in the inlet pipe may be varied.
