CARBURETER.
Specification of Letters Patent.
Patented Oct. 18, 1910.
Application filed April 22, 1910. Serial No. 556,963.
To all whom it may concern:
' Be it known that I, PAUL DANIEL, a citizen of the Republic of France, and a resident of in the county of Middlcsex and State of New Jersey, have invented a new and Improved Carburetor, of which the following is a full, clear, and exact descrip- 't-lOll.
This invention relates to certain improvements in carbureters for use in forming the explosive charge for internal combustion ongiucs, and more particularly to that type in which the liquid fuel is delivered through a spray nozzle or jet into the passage through which the air flows to the inlet valve of the engi no.
The objectof the invention is to more efliand vary the supply of liquid fuel in accordance with the flow of airf This air flow may be induced by the suction pressure of the engine orinay be induced by a 'separale cmnpressor'for deliveringair cylindrical through which the' air is delivered. The, andthe inner cy-' 1i ndrica'l wall'12 are connected together at 5 their ends, I Q:
H'u'ough the carbin'elccof the engine.
'-M V improved carburetor may be used in connection with any type of internal. conibustion engine, and may be connected atany suitable point in the system.
Reference is to be had to thc accompanying drawing, forming a partof this specification, in which the figure is a. central vertical section through a. carbureter constructed in accordance with my invent-ion.
In the specific carburcter shown I provide a casing. formed of three superposed sections 10,11 and 12, which may be designated as the inlet section, the body section and the outlet or discharge section. Each of. these is illustrated as beingformed of cast' metal and-the abutting ends of the sections have suitable flanges, by means of which the sections may be rigidly secured together. The central or body section 11 is substantially cylindrical in cross section and within the outer wallthereof is an inner substantially wall. 12, forming the passage outer-wall of the section so. as to leave an'intermediate jacket 13, through which any suitable heat ingmedium may be circulatedto facilitate the vaporizationof ,;the liquid fuel if such heating is found necessary. It is of course evident that this'jacket' may be omitted, if desired. The'inne rcylindrical wall 12 pro- .jects down below the lower endof the outer wall of the casing .11, and terminates in a transverse wall 14. Above this transverse wall, the peripheral Wallis provided with a. series of apertures 15, through which the air may enter the interior of the body section. In certain forms, the bottom wall 14 may be omitted, but by forming this bottom Wall substantially concave or dish sha-ped, as illustrated, it serves to collect any slight overflow of liquid fuel and the admitting of the air through ports around the peripheryprevents the direct flow of air through the center of the passage and tends to bring the air into more intimate contact with the liquid fuel delivered through t he'spray nozzles. A conduit 10' extends transversely across the body section 11, adjacent the lower end of the latter and above the bottom 14. This conduit may be formed integral with the casing, if desired, and at its outer end it isprovided with any suitable means for facilitating the attachment of a supply coi'ulu'itl7. On the upper side of the conduit- 16, I provide a plurality of spray nozzles, here illustrated as three in number, 18, 19 and 20. These nozzles are similar in construction, and extend upwardly from the upper side of the conduit. VVithin' .each nozzle is a valve seat and above the seat are corresponding needle valves 21, 22 and 23. Each valve seats within its correspomiin-g,
nozzle upon the valve seat thereof, and above each valve seat are passagesleading out wardly through the sides of the nozzle to facilitate the escape of the liquid fuel whenthe valve is raise Adjacent the upper end of the cylinder 12,
is a transizerse partition24 in the form of a piston valve vertically movable w'ithln said cylinder; This piston head has ads pending flange or skirt 25 of such size that the pistonis free to move vertically yet no: I material. amount of gas may escape between the piston andthe cylinder. In this flange or skirt there are a plurality of openings 26 of such size andso disposed that when the piston is in its lowermost positiomthe open.- ing's' are closed, while as the pistonjvalve raises the gas may escape out throu the openings above the upper endof the cy inder 12'. As shown, these openings have inclined upper sides, so that during the raising of the piston the rate of increase in the area ofof the openings exposed, will exceed the rate of movement of the piston. It is, of course, evident th t this could be accomplished by the aid 0 openings of other shapes than 'those illustrated. I
A The spray ndzzle 19 is located at the center of the cylinder 12 and the needle valve 22 of this spray nozzle has a valve stem extending up through the center of the piston and screw-threaded thereto. A look nut 27 is mounted on the valve stem below the piston to prevent any relative movement of the piston and valve stem. The valve stems of the two valves 21 and 23 terminate below the under surface of they piston and are supported in suitable guides 28. The valve stem of the piston 22 carries an annular flange or plate 29, and the valve stems of the two valves.2 1 and 23 have weights 30 and 31 disposed it different distances above the plate 29. Thus, as air is forced into the carburetor at the lower end the gas is sucked out" of the carburetor from the upper end, the difference in gas pressure at the opposite ends will cause the piston 24. to rise. This rising movement will uncover the openings 26 and the extent of the opening and the extent of the upward movement of the piston will vary with variations in the difi'erence in gas pressure at the opposite ends of the carbureter. A raising of the iston 2 1 raises the valve 22, so that liquid uel may escape and mix with the air passing through the cylinder 12. If theadvanoe in pressure increases so as' toincrease the flow of air through the carbureter, the piston 24 will be raised to a greater extent and the flange 29 will engage with the under side of the weight 30, which constitutes a stop, and will lift the valve 24 ofi its-seat and increase the supply of liquid fuel. A still further increase in the difference in pressure will cause the flange-29'to engage with the Weight 31 and liftthc needle valve 23 and still further increase-the supply of liquid fuel. Thus, the movement of the single piston 24 serves tova ryjthe size'of the air 0 enings, and also 'to" vary the quantity of liquid fuel delivered.
\Vithin'the upper or outlet section 12, I provi le. steps 32 for engagement WIth the upper side of the piston to limit the opening move- 1nent .-(')f" thelatter and prevent an excessive movementarid dislocation of thepartsi For :pmugi-ttipgta; still further passageofrair through -the piston aft-er the latter. has been opened-to the limiting extent, I provide air ports'j in .the piston around the center thereof, anrlcovei theseports with a valve plate 34, held in engagement with the upper side of the piston by acoil spring 35. The tension of this spring: may be varied by vary- .ing'fhc position of a ,nu,t 36. on the valve stem of the valve 22 and serving as a stop, J'o the end of; the spring.
'lhe upperor outlet section 12 a dis- Chii re'e passage 37 on one, side thereof, and to which a conduit on thevalve chamber of the engine may be connected. To guard against injury to the carburter in case of back fire the outlet section 12 is provided with a top or cover plate -38 having anoutlet port 39 therethrough. Secured to the plate and serving as -a spider to guide the valve stem 42 of a valve 43. This valve seats upon the upper surface of the" cover plate 38 and covers the port 39 in the latter. The valve is held to its seat by a heavy coil spring 44;,
move upwardly. Normally this valve re- 27 or at-any point in the systemabove the piston 26 tlievalve may rise and permit the escape of the excessive pressure. A throttle valve may be mounted at either end of the body section of the carburetor, but preferably I employ a throttle .valve 45 in the lower orinlet-section 10.
Various changes may be made in the construction and operation of-my improvedcarburetet without departing from the spirit of my invention. I
Having thus described my invention, I claim as new and desire to secure ,-by Letters Patent 1.
