WILLIAM A. EDWARDS, 01E CHICAGO, ILLINOIS, ASSIGNO'R OF THREE-FOURTHS TO CHARLES W. GILLE'IT, OF CHICAGO, ILLINOIS.
REATOMIZER.
Application died October 17, 1921. Serial No. 508,260.
2' '0 all whom it may concern:
Be it known that I, WILLIAM A. EDWARDS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Reatomizers, of which the following is a specification.
This invention relates in general to means for atomizing a liquid fuel, and while capable of many uses in connection with furnaces boilers, and other apparatus in which liquid fuel is employed, I have shown it in the present instance for illustrative purposes, as applied to a gas engine, and in this connection, it constitutesan improvement upon my pending application, Serial No. 505,713, filed October 6, 1921.
In devices which employ liquid fuel as a sourceof power, such as internal combustion engines for instance, the fuel is atomized by a carburetor or other similar device, from which it is delivered into the cylinders or other combustion chamber. In my prior application, I have disclosed a Venturi tube disposed in the path of the fuel mixture being delivered to the engine cylinders, the tube being constructed to provide a collecting pocket surrounding the intake end of the tube in which liquid fuel is collected and with extreme difliculty,
from which the collected fuel is delivered to the throat of the venturi for further atomization action. The present low grade of gasoline which is used for motive purposes containsa considerable proportion of low grade units, which can only be vaporized and by being repeatedly subjected to vaporizing action; these are the particles which are collected at the intake end of the venturi in my prior application and delivered to the throat thereof, where they are further atomized. Some of the particles, however, even after this second action, remain still in condensed form. and as they issue from the throat of the venturi they tend to move radially outwardly an along the expanding walls of the tube.
My present invention is designed to collect these fuel particles, leaving the ven- Fig. 3 is ahorizontal sectional view taken on the line 3-3 of Fig. 2;
Fig. 4 is a side elevation partially in section of a modified form of my invention;
Fig. 5 is a perspective viewof the collecting ring pocket illustrated in Fig. 4.
Referring to the drawings, 1 indicates the cylinder of an internal combustion engine surrounded by the customary water jacket 2, the cylinder being equipped'with the usual reciprocating piston 3 and communicating at its upper end with the explosion chamber 4, to which the fuel mixture is admitted at predetermined intervals through the intake valve 5, and in which the mixture is ignited by the spark plug 6; These parts and others of theengine including the vintake manifold or fuel supply passage 7 may all be of any wellknow'n or preferred construction and arrangement.
At the juncture of the manifold 7 with the passage 8 leading into the explosion chamber, I have positioned a Venturi tube, indicated generally by reference character 9, and comprising an annular shoulder or flange 11 adapted to fit snugly in the groove formed jointly by the manifold and the adjacent wall of the cylinder block. At its outer intake end, the external diameter of this tube is reduced, as will be apparent from Figs. 1 and 3, providing a circumferential collecting chamber or pocket 12 between the perimeter of the tube and the surrounding walls of the manifold. The fuel particles in the, charge vdelivered from the manifold are collected in this pdcket, from whence they are conducted to the throat of the venturi for reatomization purposes by a duct 13, establishing commu nicatioIr between the pocket and the throat pass axially from the venturi into the passage 8 are returned by gravity through a passage 14 beneath the delivery end of the venturi to the forward or inner face of the flange 11, from whence these particles are.
returned to the throat of the venturi for further atomization action by a duct 15 establishing communication between the passage 14 and the throat of the tube.
The major portion, however, of the liquid fuel particles issuing from the venturi, tend to expand or travel radially along the outwardly flaring walls of the tube, and it is for the purpose of collecting these par-' ticles and returning them to the throat of the venturi for further atomization or breakin up that my present invention is designed.
In order to effect this result, the Venturi tube is provided at its delivery end with an inwardly extending flange 16 forming an annular collecting ocket 17 at the mouth of the tube. The uel particles are intercepted by this flange and collected in the pocket, where they flow by gravity to the lowest point thereof. Communication is established between this point and the throat of the venturi by a duct 18 so that the suction exerted in the throat of the venturi upon this duct draws the liquid fuel particles from the collecting pocket back into the throat of the venturi, where they are further atomized. Should this reatomizing action fail to break up the particles,
they will be caught *a second time in the pocket'and again returned to the throat, and this action will be repeated as often as the particles are cau ht in the pocket.
In addition to co lecting the fuel particles issuing from the venturi, this flange at the mouth of the venturi sets up a whirling motion in the vaporized mixture of fuel and air being delivered from the tube, or in other words, establishes a turbulent condition in the mixture which facilitates and augments the atomization and diminishes the condensation, so that the mixture is de-" livered into the combustion chamber in a conditionmost favorable to the exertion of maximum power effort.
The flange 16 illustrated in Figs. 1 to 3 inclusive, is shown as constructed integrally with the body of the tube, but in Figs. 4 and 5, I have shown a modification in which the collecting pocket 19 is provided by a flange 21 formed upon the end of a sleeve or thimble 22 ada ted to fit over the delivery end of the Ven uri tube 23, which in this instance, is preferably circumferentially grooved, as indicated at 24, to receive this sleeve. The collected fuel particles are returned from the pocket 19 to the throat of the venturi through a duct or passage 25 similar in construction and function to the duct 18 previously described.
