UNITED STATE .ARTHUR ERNEST PAYNE, 013"V TWICKENHAM, ENGLAND..
FUEL NOZZLE OFSNYRAY CARBURETOBS.
Application filed Marc-h 20, 1924. Serial No, 700,676.
To all whom t may concern.'
` Be it known that ARTHUR ERNEST PAYNE, a subject of the King of Great Britain, residing at St. Margarets, Twickenham, Middlesex, England, has invented certain new and useful improvements in the Fuel Nozzles of VSpray Carburetor-s, of which the following is a specification.
The invention relates to a fuel nozzle for use in spray carburetors which is particularly adapted for use with the carburetor described in my British Patent 161,367 but may be used with other types of spray carburetors, such nozzle having the advantage that the fuel does not leave the nozzle in solid liquid form as is usual with mosttypes of carburetor nozzles but is broken up into minute particles which, mixing with the air, enter the combustion chamber of the engine perfectly atomized.
My construction of nozzle comprises a main tubular body receiving its supply of fuel from the float chamber, such body having a recessed or shallow dished shaped portion at its upper part which is kept filled with fuel from the float chamber. Surrounding the upper part of this main body is fitted a cap having its head externally coned and having slots cut radially therein, holes being formed at an angle in the base of the slots leading to the inside of the cap. The top of the cap is centrally recessed, and surrounding this cap and secured to the main body is another cap or sleeve of larger diameter than the first named cap so as to leave a space between the two caps. The inside of the end of the outer cap is shaped to rest on the coned end of the main cap and is provided at its centre with a hole coinciding with the recess in the head of the main cap but of inverted cone shape. There are also air holes around the base of the outer cap or sleeve.
My invention will be more clearly understood from the following description aided by the annexed drawings in which- Figure y nozzle with the parts assembled.
Figure 2 is a plan of same.
Figure 3 is an elevation and Figure 4 a plan of the cap. v
Figure 5 is a part sectional elevation of a carburetor having my nozzle applied thereto.
The centre main body 1 of myv nozzle or atomizer its cylindrical in shape and has a 1 is a longitudinal section of my.
threaded end 2 for attachment to the carburetor and has a central passage 3 for fuel with a shallow dish 4 formed in its upper portion which is filled with fuel from the iioat chamber 'of thecarburetor.
The body 1 in addition to having a threaded end 2 for attachment to the carburetor, is also screw threaded at 6 on its outside diameter to receive a cap or sleeve 7.
There is a flange 8 situated between the two threaded portions 2, 6 which may be of hexagon form for general convenience of assembling.
The exterior of the upper. portion of the main body 1 is reduced in diameter to receive a cap 9 with which it has a sliding ii't` and the lower end Vof the cap 9 rests against a. shoulder 10 formed on the'main body 1.
AY space 11 exists between the upper end of the centre main body 1 and the cap 9.
The upper end of the cap 9 is conical and fits against the inner face of the conical head 12 of a sleeve 7 which is internally threaded at its lower end to engage the screw threaded portion 6 of the main body 1 so as to secure the cap 9 in position on the main body 1 of the atomizer c The upper end of the cap 9 is also recessed at 13 and through the walls of the recess are a series of radial slots or iutes 14 directed upwardly from the periphery of the cap towards the center.
A small hole 15 extends from the bottom of each slot or flute to the interior of the cap 9 for the passage of fuel from the bore of the main body of the atomizer, such holes being directed Vupwards away from the centre.
The outside sleeve 7 of the atomizer has a central inverse conical aperture 16 in its upper end and the inner surface of said end is formed conically of the same angle as the cone part of the cap 9 on which it rests.
' The lowerv portion of the outside sleeve 7 has a hexagonal wrench engaging portion above which are a number of air holes 17.
The exterior of the upper end of the sleeve 7 `may be conical, rounded or of any other shape.
I may also arrange the centre main body of the atomizer to take a simple form of screwed needle valve of the usual common type for regulating the ow of fuel in place of the submerged jet if desired.
A restricted passageway 18 formed between the choke tube 21 and the upper portion of atoinizer causes air to be drawn through the air holes 17 in the sleeve 7, Which are open to atmospheric pressure. This air passes up the annular space 20 between the sleeve 7 and the cap 9 and through the small slots or flutes ll in the upper end or' the cap 9V carrying; with it a certain amount ot' fuel from the small holes l5 in the bottoms oi" the slots 14, thereby setting up inside the upper end of the atomizer a nu1nber oi' diierent air streams which are directly opposed to each other, and which meet in the centre of the aioniizer= breaking up and atolnizing the fuel, which finally emerges from the centre hole 16 ot the atomiZer Where it is diluted and finally vapourized by the main air stream passingl through the carburetor trom the inlet 2l.
By this construction7 I obtain a very low consumption of fuel, and an increase of power and iiexibility of the en gine combined with rapid acceleration.
vWhat l do claim as my invention and desire to secure by Letters Patent, is
A fuel nozzle for spray carburetors cornprising a main tubular body havinga shallouT dish in its upper enc., a cap itting such main body and having` a conical-shaped upper end provided with a central recess, said cap also having radial slots formed in it-supper end and directed upwardly from its periphery to said recess and apertures through the bases of the slots directed upwardly toward the periphery of the cap, a headed sleeve of larger diameter than said cap secured to the main body and having the interior of its upper end shaped to corre-l spond with the conical exterior of the upper end of the cap and resting on the latter, said sleeve having a conical aperture in its upper end and air holes adjacent its lower end, substantially as and for the purpose set forth.
' ln testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
ARTHUR ERNEST PAYNE.
