MIXING DEVICE FOR CARBURETORS Original Filed May 1925 y wi w Patented June 18, 1929.
UNITED STATES .IOHANNES B. KESSEL, OF CHICAGO, ILLINOIS.
MIXING DEVICE roe GARBURETOREi, U 1 I Original application filed May 2, 1925, Serial No. 27,382. Divided and this application filed November 1 1, 1926. Serial No. 145,393.
This application is a division of my orig inal application, Serial Number 27,382, filed May 2, 1925, Patent Number 1,636,187,dated July 19, 1927.
This invention relates to improvements in mixing devices particularly adapted though not necessarily limited in its use, in connection with carburetors, and one of the objects of the same is to provide improved means whereby there will be a thorough mixing of the air and fuel and at the same time the cylinder of the engine will be supplied with fully described and claimed and shown in the accompanying drawing illustrating this invention and in which Figure 1 is a vertical sectional view of a carburetor of this character constructed in accordance with" the principles of this invention.
Figure 2 is an enlarged top plan view of one of the spinners, with parts omitted.
Figure 3 is a detail sectional view as taken on line 3-8, Figure 1.
Referring more particularly to the drawing the numeral 10 designates generally a mixing chamber in which the fuel and air are mixed and is supported in the usual manner by means of a flange'll.
The bottom of the mixing chamber is open and extending'thereacross is a screen 12 to permit the air to enter the mixing chamber and toexclude foreign particles; Discharging into the mixing chamber is a needle valve casing 13 which receives its supply of fuel from any suitable source through a pipe 14 supported in any suitable manner. Arranged within the casing 13 is anadjustable valve" seat 15 whichis arranged adjacent suitable outlet openings 16 in the casing wall and through which outlets the fuel flows after encompassing the I discharge outlets I of the passing the valve seat 15.
A needle valve 17 coroperates with the valve seat 15 and the valve is guided in its movement preferably by means of an enlargementor collar 18 carried by the valve and engaging the wall of the casing 13 above the valve seat; The collar also servesas a means for limiting the movement of the valve in one direction. a
A cap 19 is removably secured to the top of the casing 13and through which the stem of the valve passes to be guided thereby.
Connected with the upper end of the valve stem is adisc like element 20 preferably of a concave shape and is of a suitable diameter that when the throttle valve 30 is opened and suction in the engine cylinder is manifested in the mixing chamber, the suction will operateupon the element 20 to raise or unseat the valve 17 from the seat 15 and "thereby permit the fuel to flow out of the openings 16 in the valve casing v "A plug 22 may be provided and is removably seated in an opening in the pipe 14: in alinement with the valve seat 15.so thatby removing the plug the valve seat may be adjusted asdesired.
Encompassing the casing 13 is the hub 23 of a. spinner member, which latter is provided with any suitable number of wings or blades 24. One end of the hub rests upon a bearing 25 which encompasses the valve casing 13 and is supported thereby below the openings 16. The other end of the hub has a bearing against the cap 19. c I Y The internal diameter offithe hub 23 is PATENT OFFICE;
somewhat largerthan the external diameter of the adjacent portion of the valve casing13 so as to form a chamber 26 therebetween and with which "chamber the openings 16 have communication so thatthe fuel flowing from the openings 16 will enter the chamber 26 in the hub 23 of the spinner, and will be delivered therefrom through openings 27 as the spinner and hub rotate and whichopenings are'loeated preferably adjacent one end of the-hub. t 1
The cap 19 is preferably of a diameter somewhat larger than the end of the hub and assists in directing the stream offuel which is being emitted through the openings 27, and the diameter of the disc likeelement 20 is also such that the fuel will impinge the face which valve'the spinner and the needle valve is located. 4
The above referred to parts constitutethe subject matter of my original application above referred to.
Disposed on the opposite side of the valve '30 is a rotor device designatedgenerally by the reference numeral 31 which may be of any desired configuration but preferably em'-. bodies an annular member having a plurality of blades or wings 32, any number of which may be provided, extending from the'inner periphery of the member towards the diametric center thereof. These wings 32 are "preferably inclined upwardly and are slightly twisted so as to give a spiral formation to the blades. Y
The rotor 31 is preferably provided, with ball bearings 33 supported by a shoulder 34 formed in the wall of the mixing chamber and a bearing member 35. This member 35 (see particularly Figure 3) is provided with openings '36 extending therethrough and arranged at aetangent to the periphery of the rotor. Achamber 37 is provided adjacent the.
Any number of blades 38 may be provided as well as any number of openings 36.
Communicating with the chamber 37 is an air supply pipe 39 the inlet endof which is controlled-by a valve 40, the latter being normally heldin a position to close the inlet opening preferably by means of afspring- 41. A pipe 42 has communication with the valve chamber and also has communication as at 4.3 I
with the mixing chamber 10 preferably above the rotor 31, so that the suctioncreated in the engine will be manifested upon the valve 40 through the pipe 42 to actuate thevalve to open the inlet pipe 39 and thereby permit air 7 to flow. into the chamber 37 to be discharged through the openings 36 against theblades 38 of the rotor 31.
Thi'sflow of air is augmentedby the engine suction and the engine suction will also oper- V ate to rotate the rotor 31.
With this improved construct-ion V seen that there isprovided a 'gas and air mixing device located on opposite sides of the throttle valve 30, with the result thatthe ina will be r coming air and gas will first be thoroughly mixed at the point where the gas leaves the supply nozzle. \Vhen the throttle valve 30 is opened to" allow the mixture to pass it will come in contact with the rotor 31 and at the same time an additional supply of air will be mixedwith the mixture, the rotor 31serving as an additional means for breaking up all of the particles of gas to produce a thorough mixture. Obviously the rotor 31 may be located on either side of the throttle valve 30.
It is thoughtthat the operation will be clearly understood from the foregoing but,
briefly stated it is as follows. Assuming the valve 17: to be seated the suction created in the engine cylinder will, when the throttle V valve 30is opened, be manifested in the mixing chamber and will operateupon the disc 20 carried by the needle valve 17 to raise the valve and will allow the fuel to flow through the pipe let, into the needle valve casing, out of the openings 16 and into the chamber '26 in the spinner, suction also tending to draw the fuel through the openings 27 in the spinner.
The suction will also be manifested upon the blades 24 of the spinner and will cause the same to rotate as the air is drawn in through the screen 12. As the air passes through the venturi 28 it contacts with the fuel being delivered through the openings 27 in the spinner. The operation of the spinner will cause a rotary or swirling movement to be given to vtheair and also to the fuel, with the result that there will be a thorough mixture or commingling 0f the air and fuel in the mixing chamber. a
Vhen the mixture passes the throttle valve 30 it will come into contactwith the rotor 31 and additional air which is being drawn through the pipe 39 into the chamber 37 will be delivered to the mixture in the mixing chamber and will, through the medium of the rotor 31, be thoroughly mixed with the mixture, the rotor 31 operating to break up all of the particles of gas, resulting in a thorough mixture. i
It will be manifest that the operation of the rotor and the spinner aswell as the'operation of the needle valve and thevalve lOWlll be controlledby suction created in the engine cylinder.
.lVhile the preferred form of theinvention has been herein shown anddescribed it is to be understood that various changes maybe madein the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit ofthis invention. I i
