Application led April 7, 1918. Serial No. 89,615.
' of Utah, have invented certain new and useful Improvements in Carbureters; and I do hereby declare the following to be a full, clear, and exact descriptionI of the invention, such as will enable others skilledin the art to which it appertains to make and use the same. c
This invention has for its object to provide an improved carbureter embodying such novel features of construction as to insure complete vaporization of the liquid fuel and a thorough mixture of the vapor with an adequate quantity of air.
With this and other objectsin view, the invention consists inthe novel` construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:
Figure 1 represents an end elevation of the improved carbureter,
Fig. 2 represents a side elevation thereof, Fig. 3 represents a transverse sectional view on the line 3-3 of Fig. 1, and v lfig. 4 represents a sectional view on the line 4-4 of Fig. 3. I
Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates generally the hollow body or casing of thecarbureter including circular side walls and'end walls 6. One end wall is formed with an air inlet port 7 and the opposite end is connected with a coupling 8 adapted for connection with the inlet manifold of an internal combustion engine (not shown).
A partition 9 is arranged within the hollow body in spaced parallel relation to the end walls 6 thereof and is formed with a centrally located opening 10, preferably arranged in line with the air inlet opening 7 and the coupling 8 and dividing the interior of the body into two mixing chambers 11 and 11,
Circular and imperforate deflector plates 12 and 12L are arranged centrally within the chambers 11 and 11a in concentrcally spaced relation to the side wall of the body 5, the deflector plate 12 which i's disposed adjacent the coupling 8 being connected by a plurality of curved ns or blades 13 with the partition 9 and .the delector plate 12 which is arranged adjacent the air inlet 7, being connected with thefadjacent end wall 6 of the body by a plurality of blades 13. As clearly illustrated in Fig. 4, the inner extremities of each set of vblades 13 and 13a are connected in the line of the longitudinal axis of the body 5, and the outer ends thereof which terminate in uniformly spaced relation are also spaced from the side wall 5 of the loody. A pair of substantially conical perforate or foraminous members 14 and 15 are arranged between one of the end walls 6 of the body and the adjacent deiector plate 12@ and the partition 9 and the other deector plate-12, and the apices thereof are directed toward the air inlet port 7.
A plurality of fuel spraying nozzles 16 are extended through the side wall of the body 5 and -the inlet port 7, and are preferably directed toward the axis of the body`I The nozzles 16 are supplied with a suitable com-- bustible liquid by a fuel supply pipe 16a and the passage of liquid fuelthrough the supply pipe may be controlled byany preferred type of manually operable valve (not shown).
As clearly illustrated in Fig. 2, the side wall of the body is formed with a pair of spaced and circumferentially elongated auxiliary air ports 17 for admitting an additional supply of air to the interior of, the
carbureter. The passage of air through the auxiliary portsis controlled by a pair of pivoted valves 18 pivotally secured at 19 to the sidewall of the body and having the inner ends overlapped and provided with longitudinal slots 20, receiving a laterally projecting pin 21 of an adjusting rod 22, whereby the valves 18 may be simultaneously adjusted.
During the receding or suction stroke of Vthe piston of the explosive engine, air is drawn through the air inlet port 7 and is primarily mixed with the fuel discharged by the nozzle 16 located in the wall of the `inlet port 7 and is subsequently directed against the irst deiector plate 12, and, continuing to flow through the body, the inowmg mixture is drawn between the blades 13, which latter impart a whirling motion to the mixture. The inflowing mixture is successively drawn through the conical screen 14, opening 10, between the blades 13 and finally through the chamber 11 and foraminous member 15 into the coupling 8, by which it is conducted to the inlet manifold of the engine. From the foregoing it is clearly evident that, during vthe passage of the mixture through the carbureter it is gradually enriched by the liquid fuel drawn in through the several nozzles 16 and the vaporized liquid is thoroughly mixed with air and thus rendered highly explosive. When desired, an auxiliary supply of air4 may be admitted to the interior of the body 5 by opening the valves 18, which lattermay be accurately adjusted by means of the actuating rod 22 to admit the proper quantity of air in p roportion to the quantity of liquid fuel discharged from the nozzles 16.
What l claim is:
l. ln a carbureter, a hollow cylindrical body having an air inlet port in one end thereof, a deiector plate arranged within said body and in spaced relation to the side Wall thereof, a fuel nozzle secured in the side wall of said body having its open end directed toward the axis of the latter, and a plurality of curved blades arranged between said inlet poi-tand said deector plate and extending outwardly from the axis of said body and terminating in spaced relation to the latter. f
2. In a carbureter, a hollow body having inlet and outlet ports therein, fuel nozzles extending into said body, an apertured partition arranged in said body dividing the latter into mixing chambers, deflector plates arranged in said chambers, a plurality of blades associated with said deector plates and-extending outwardly from the longitudinal axis of said body, and substantially conical foraminous members arranged .in said chambers.
3. In a carbureter, a hollow body having inlet and .outlet ports therein, fuel spraying nozzles extending into said body, a partition arranged cent-rally Within said body and having a central opening therethrough, delector plates arranged on opposite sides of said partition, curved blades associated with said deflector plates and extending outwardly from the longitudinal axis of said body, substantially conical screens arranged in said body on opposite sides f said partition. A
4. ln a carbureter, a hollow body, fuel nozzles extending into said body., deflector plates arranged in said body, curved blades arrangedin said body and associated with said defiector plates, said body havingr auxiliary air ports in the side wall therecf, pivoted valves for controlling the passage of air through said auxiliary air ports, and having the free ends overlapped and slotted, an actuating rod, and a head positioned laterally of said actuating rod and extending through said slots.
5. In a carbureter, a hollow body having an internal mixing chamber` fuel nozzles extending into said body, a deflector plate arranged in' said body, curved blades arranged in said body and associated with said deflector plate, said body having auxiliary air ports in the side wall thereof, and means for controlling the passage of air through said auxiliary air ports.
In testimony whereof I aiiix my signature in presence of two witnesses.
