3 Claims. (Cl. 26137) This invention relates to improvements in a fuel supply and fuel atomizing device for internal combustion engines and more particularly to a fuel atomizing device which will feed fuel into an intake manifold of an engine, with the engine in any position.
Various devices have been proposed heretofore for supplying and atomizing fuel, but these, for the most part, required the use of floats, which necessitated the engine being maintained in a substantially upright position at all times, or required fuel injector devices which injected solid fuel directly into each cylinder of the engine.
The present device is so designed that fuel is maintained under pump pressure in a chamber adjacent the intake manifold of a conventional internal combustion engine of the two or four cycle type, and which fuel is fed into an atomizing chamber under pressure, by a throttle or acceleration valve so as to give the desired speed.
An object of this invention is to provide a fuel atomizer and injector in which fuel is conveyed to a fuel accumulation chamber adjacent the manifold of the engine by a pump, wherein pressure is maintained on the fuel within the fuel accumulation chamber to inject the fuel into the manifold, where the fuel so injected, is further atomized therein, first by a rotating beater element and secondly by means of a screen within the throat of the air passage leading to the engine cylinder.
Another object'of the invention is to provide a second injector and atomizer which has a valve system that is readily controlled by means of a throttle valve lever.
Still another object of the invention is to provide a fuel injector and atomizer having an automatic choke device which will automatically open to pass a proportionate amount of fuel, as the suction within the manifold of the engine increases.
Yet another object of the invention is to provide a fuel injector and atomizerwhich is simple and sturdy in constmction, efficient in operation and free of operating defects.
With these objects in mind, and others which will become manifest as the description proceeds, reference is to be had to the accompanying drawings, in which like reference charactersdesignate like parts in the several views therein, in which: Y V

Fig. 6 is an enlarged, fragmentary, vertical sectional view taken through the fuel accumulating chamber; and
Fig. 7 is a fragmentary view taken on the line 77 of Fig. 6, looking in the direction indicated by the arrows.
With more detailed reference to the drawing, the numeral 1 designates generally the manifold of a two or four cycle internal combustion engine, such as an auto- A fuel supply reservoir 2 is provided wherein a suction pump 4 withdraws the fuel from reservoir 2, through suction line 6, and discharges the fuel, such as gasoline or the like, through pipe 8 into the fuel accumulation chamber 10. The fuel accumulation chamber 10 has a pressure relief valve 12 therein, so when the pressure within the chamber 10 reaches a predetermined setting, the relief valve 12 will indicate the pressure within the chamber it) having reached this predetermined setting, and the fuel will escape through by-pass line 14 to a Y-connection 16 interconnecting with suction line 6. In this manner the surplus fuel, which is discharged out through relief valve 12, re-enters suction line 6, without having to pass into fuel reservoir 2, thereby obviating the necessity of withdrawing the fuel from the reservoir twice.
It is preferable to have the fuel accumulation chamber 10 either made integral with, or secured to the atomizing chamber 18, which leads to the manifold l of the engine. In the present instance, the fuel accumulation chamber 10 is shown to be bolted to the atomizing chamber 18 by means of bolts 20. A sealing gasket 22 is provided between the fuel accumulation chamber and the atomizing chamber so as to insure a tight seal therebetween, so as to hold the fuel under pressure in the chamber 10.
The wall of the atomizing chamber adjacent to the fuel accumulation chamber, has two conical apertures 24 and 26 formed therein, which apertures 24- and 26 complementarily receive the respective valve body members 28 and 30, which are conical in shape, as will best be seen from Figs. 2 and 6. The valve body 23 has a bore 32 therein, which has a valve seat 34 on the inner terminal end thereof. The inner end of the valve body 3% has a recess 36 formed therein from which holes 38 radiate, as will best be seen in Figs. 6 and 7, so as to discharge the fuel in finely divided particles, into the atomizing chamber 18. A valve stem 40 has a conical face 42 formed on its inner terminal end to seat on complementary valve seat 34. The stem 46 is smaller than the bore 32, thereby an annular chamber is formed around the stem 40. A sealing ring 44 closes the outer end of the annular space between bore 32 and valve stem 40, which sealing ring may be in the form of an O-ring.
The recess 46, in the valve body may be filled with packing, and may be held in adjusted relation by means of a nut 48. Both the inner and outer diameters of valve body 28 are threaded, the outer diameter thereof being adapted to threadably engage the outer end of the body of the fuel accumulation chamber 10, said outer diameter of the valve body also being adapted to receive a lock nut 50, with a gasket 52 thereunder, so as to insure a tight fit between the valve body 28 and the body of the chamber 10.
l he inner diameter of the valve body 28 threadably receives packing gland nut 38, the interior of which packing gland nut 48 is also threaded to threadably receive the threaded portion 54- of the valve stem 49. A screwdriver slot 56 is provided in the outer end of the valve stem 40 to enable the adjustment thereof.
The valve body 28 has one or more apertures 58 formed therein which admit fuel from the fuel accumulation chamber it) into the annular passage formed by valve stem at and bore 32 of the valve body, so as to pass fuel therethrough, when pressure is exerted on pipe 8 by pump 4. This valve 28 is a valve that is usually termed a slow speed or idling valve, which will admit suflicient fuel to enable the engine to maintain an idling speed. A second valve'body 3G is 'of similar construction, in all respects, to valve 28, except the valve 3% has a stem 62 which extends outward through'packing gland 64, and which stem 62 has a lever 66 on the outer terminal end thereof. The lever 66 is connected, by means of a linkage 68 to a second lever 7t onthe shaft 72 of a butterfly valve 74, which butterfly valve 7% is positioned within the passage leading to the intake manifold 1.
A second linkage '76 is connected to lever '74 and extends to a remote point, such as the throttle, foot accelerator or the like, so as to enable the butterfly valve '74 to be opened simultaneously with the unscrewing or opening of the valve (:2, which valve stem has screw threads 63 thereon, which threads =53 complementarily engage screw threads within packing nut 64. An air inlet pipe 78, which is attached to atomizing chamber 13, has an air filter 83 therein, which conducts the air through an automatic choke valve 82, to atomizing chamber 18. The choke valve 82 is pivotally mounted with a greater area on one side of the pivot than on the other, so as to be automatically responsive to suction within the manifold 1. A spring is attached to choke valve lever 86, and an adjustable nut 83 is attached to spring 84, so as to enable the correct tension to be applied to spring 554 so the choke valve will open to give the correct amount of air into the atomizing chamber 18.
A rotary, wind-responsive turbine element 9% is mounted on trunnion shaft 91 within atomizing chamber 18 and is so positioned that the multiple sprays 38 of valve body 23 and valve body 3% will be directed onto the rotary turbine element $49, which rotary turbine is driven by motion of the incoming air, and the movement of which thoroughly atomizes the fuel particles, to give the proper mixture for the combustion of fuel within the cylinder of the engine.
The pressure within fuel accumulation chamber ll) may be varied according to the construction of the particular engine, and may be operated from a few pounds pressure to an excess of one hundred pounds pressure, depending on the result desired to be attained. However, for purposes of illustration, a pressure of four pounds may be maintained within fuel accumulation chamber in, and if the volume of fuel pumped is in excess of the volume of fuel being used, the excess fuel will be by-passec through relief valve 32 to the bypass line 14 and thence back through Y-connection to the suction side of pump However, a pressure gauge 96 is provided, which may be connected, through a conduit, to pressure accumulation chamber it so as to readily present a means of determining if the fuel within the chamber is being maintained at the proper pressure.
Operation \Vith the device installed on the intake manifold of an internal combustion engine, the fuel is withdrawn from reservoir 2 through suction line 6 and discharged through pipe 8 to fill and maintain fuel under pressure in fuel accumulation chamber When a predetermined pressure, in chambe' 3rd, has een reached, the relief valve 12 is set to open to bypass fuel back through pipe 14 through if-connection in suction line 6, and with the valve stem of valve 2?, properly adjusted to give an idling speed, fuel will pass through holes 53 into bore 32 and between conical face and valve seat 34, so as to be forced outward through holes 33 into atomizing chamber 18. The fuel so discharged will strike rotating turbine element 90 so as to break up the fuel particles, which becomes a finely atomized mixture, when mixed with air. The centrifugal force exerted by the turbine will direct the fuel particles against and through the screens 92 and 94- to further atomize the fuel particles so as to produce a highly combustible mixture, when drawn into the manifold 1. V
A butterfly valve 74 is positioned in the throat of the intake manifold l and is connected by a linkage 68 to valve stem 4%, so upon moving linkage 76 connected to a throttle lev he valve stem 44) will be so rotated as to move ti al face of the valve stem away from the seat so as to give a correctly proportioned amount of gasoline or other fuel'into the atomizing chamber for the correct mixture in accordance with the opening of the tte -fly valve 74. Furthermore, the choke valve 82 will the correct amount to provide a combustible mixture which will produce the maximum efficiency from the fuel.
An air cleaner till is provided within intake line 78 so as to provide clean air to be admixed with the fuel in the atomizing chamber 18. It is further to be pointed out that the rotary turbine element 913 is off-set with respect to the main line of passage of air from air inlet pipe 7%, to manifold 1, thereby making possible the driving of the rotary turbine element 95) by the passage of air into the intake manifold i.
It is to be pointed out that, with the present invention, the valve 23 and the valve sa may be readily removed, adjusted and replaced, thereby enabling the device to be serviced in a minimum of time, and since there is a minimum of working or moving parts, there is little likelihood of wear or of the mechanism getting out of adjustment.
While the invention has been described and claimed in one embodiment thereof, it is to bc understood that changes may be made in the minor details of construction, and adaptations made to different installations, without departing from the spirit of the invention, or the scope of the appended claims.
Having thus clearly shown and described the invention, what is claimed as new and desired to secure by Letters Patent is:
