Abstract
499,867. Spray carburetters. SCHIMANEK. E. June 25, 1937, Nos. 17702, 17703., and 17704. Convention dates, June 25, 1936, Aug. 18, 1936, and March 3, 1937. [Class 7 (iii)] The injection pressure of fuel delivered under pressure into the air path leading to the cylinder is controlled by at least one pressure regulator which is itself controlled in dependence upon the quantity of air flowing to the engine, i.e. in dependence upon the weight of air dealt with and upon the loading and speed of revolution of the engine. Fuel supplied under pressure through a pipe 15 to a chamber 10 is controlled by a valve 14 mounted on a diaphragm 11 and a rod 15 connects the diaphragm 11 to a second larger diaphragm 12, the chambers 9, 8 between the diaphragms and below the diaphragm 12 being connected respectively to the throat 6 of a Venturi 4 in the main air passage 1 and to the widest part 7 of the passage ; the valve 14 is thus controlled by the combined action of the diaphragm 11 subjected to the lowest pressure, i.e. at the throat 4 and the larger diaphragm 12 subjected to the difference between the pressures at the points 6, 7, and tends to open against the fuel pressure as the suction increases. Air supplied through a passage 20 emulsifies the fuel as it is sprayed from a nozzle 21 placed close to the chamber 10 and the resulting mixture is introduced at any desired point in the passage 1 which may have either an anterior or posterior throttle. In the former instance, an additional diaphragm may be secured to the diaphragms and the additional chamber be connected to the air passage in front of the throttle to compensate for barometric pressure. In the latter case, a separate diaphragm unit may be provided to function during idling and like periods. As shown in Fig. 3, the diaphragms 40, 41 are of equal size and the throat of the Venturi 4 communicates with the chamber 38 between the diaphragm 41 and the casing while the chamber 39 between the diaphragms is connected at 7 to the wide part of the air passage. The connection between the diaphragms comprises a toggle linkage 25 which converts the downward force exerted by the suction on the lower diaphragm 41 into an upward force on the diaphragm 40. The fuel is supplied by one or more pumps for each regulator or group of regulators.
