P. scoTT ATOMIZER VALVE Filed March 17, 1924 Zig/S,
Patented Aug. 10, 1926.
` UNITED STATES PATENT OFFICE.
Application led March 17, 1924. Serial No. 699,836.
This invention relates to an atomizing valve, and particularly to an atonfnzlng valve of the type ada ted for use 1n 1njecting fuel into an lnternal combustion engine cylinder, although this valve mayhof course, be used in any connection 1n which it is necessary or advantageous. to use an atomizing valve. Among the objects of In invention are; to provide a valve whlch w1 l have an exceedingly minute opening; to provide a valve of such construction that it tends to free itself from dirt and foreign material in general; to provide a valve which will be non-clogging;y and to provide a valve having a plurality of separate discharge orifices. Other objects will appear'V from time to time throughout the specification and claims. c
My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:
Figure 1 is a vertical cross sectlon of my valve;
Figure 2 is a plan view of the valve disc;
Figure 3 is a cross section on an enlarged scale showing the valve construction in detail.
Like parts are indicated by like characters throughout the drawings.
A is a valve body having a. central bore A1, with which the feed bore A2 is in communication. B means of this latter liquid is supplied to t e valve for atomization.
B is a disc retaining cap, threaded upon f the lower end of the valve body A. It is adapted to hold in place the valve disc C.
This disc C is resilient so that it will yield slightly under the high pressures to which it is subjected and is positioned against the packing C1, which rests upon the f ,lower end of the valve ,body A.
On the upstream face of the disc is the raised circular land D. This land may be of any suitable shape or number, but a single one being shown and that of annular shape. Through the land are a number of perforations C2, across the edges of which the liquid is fed and atomized. It will be noticed that these perforations increase in size on the downstream side of the disc.
Positioned within the centr-al bore A1 of the valve body A is the valve stem E mounted in the retaining yoke E1, having threaded u on it the adjustin nut E2 by means of wl'iich it is raised or owered.
On the lower end of the valve stem E is the plug F, which is provided with the inclined erforations F1. It will be understood t at these perforations are not necessarily inclined.
Where the expressions upstream or downstream are used in this specification, or in the claims, they are used respectively to mean the side nearest the source of pressure and the side farthest from the source of pressure. Thus the upstream side of the disc is the inside of the disc when the disc is discussed with reference to the valve body, and it is the side of the disc which is closest to the source of fuelsupply and ressure. Tlie downstream side is obviously t e other s1 e.
Although I have shown an operative device, stil it will be obvious that many changes in size, shape and arrangement of parts 'might be made without departing materially from the spirit of my invention; and I wish, therefore, that my showing be taken as in a sense diagrammatic.
The use and operation of my invention are as follows:
When the valve is toy be used it is connected to a liquid supply system by means 'of which liquid preferably under heavy pressure is supplied to the interior of the valve body. As the parts are originally assembled and fitted, the valve stem is screwed down until the plug at its downstream end is positively and firmly seated upon the raised land, or lands, of the valve disc. It thus completely closes the perforations through the disc. When the liquid is supe plied it passes through the central portion of the valve body and comes in contact with the valve disc, strikes the valve plug and passes through the perforations in it. When the pressure becomes suilicient the valve disc is bent or deflected away from contact with the valve plug as shown in Figure 3. This obviously opens the perforations and atomized liquid is discharged through the disc. When the pressure is decreased, the disc again moves back into sealing contact with the plug and so no further discharge takes place.
Should there be any particles of dirt or foreign material of any nature whatever in the liquid, they will tend to be caught against the land, or lands, and will not pass through lthe atomizing orices because the space betweenthe face Aofthe 'land the face of the plug is so exceedm ly minute even with maximum opening t at no ordinary dirt particle can enter that space and because there is sui'cient space between the face of the plug and that of the face from which the land projects for any or dinary accumulation of dirt to be deposited there without buildin up in front of the sharp edge or disc large' spray orifice. While dirt may be caught in this space, 1t will be free to move around as eddy currents are set up during atomizing movement of the liquid and no matter where .a dirt particle laces itself, owing to the great length o? the opening due to lts thlckness, dir t particles will not accumulate through- Y out the length of the orifice in sulicient quantity to interfere with the passage of the liquid and in order to stop the operation of the valve, it will be necessary for the dirt particles to accumulate around the periphery in a solid mass which is a contingency exceedingly unlikely to happen during the life of any spray atomizing disc. In the event that any particles small enough to get into the spray opening should appear, the fact that the discharge passage from the spray point is much larger than the spray openin will make sure that such particles will easl y escape and will not remain in the valve or between the atomizing surface or interfere with the valve operation.
` It will be understood that the parts as shown are greatly magnified.
