Description
April-12, 1932. E. M. WHITE PRESSURE INCREASING DEVICE Filed Oct. 26, 1928 gmento'c ErnesZ/Z Mai e Pat ented Apr. 12, 1932 EanEs'r M. WHITE, or nos ANGELES, CALIFORNIA reassess rivcnsnsme DEVICE This invention relates to pressure increasing devices and particularly to a supercharger for use with internal combustion en- M gines, compressors, blowers, exhaust fans 5 and in fact with any device wherein and whereby the weight or volume of fluid is to be increased over that which would normally be delivered to any of the aforesaid device s. M An object of the invention is the provision stance as a supercharger that is operated solely by an associated object and in accordance with operating conditions of said object. Another object is'the provision of a simple and efiicient supercharger that is automatic in its operation. i
The present invention is'so arranged that a greater weight of air or other fluid may be h delivered at all times to an associated object in accordance with the requirement.
Other objects will appear as the specifica-- tion proceeds, among which objects is to increase the volumetric elficiency of any device with which the inventlon 1s associated, and
with the various objects above enumerated,
and others, the lnventlon consists in the novel j and useful provision, formation, construction, association and relatlve arrangement of parts members and features, all as shown in a certaln embodiments in the accompanylng drawings, described generally, and more particularly pointed out in the claims.
, In the drawings: Figure 1 is a side elevation of an internal combustion engine incorporating the improved invention,
Figure 2 is a side elevation of the invention associated with a pump,
Figure 3 is a cross sectional view of the invention of the form incorporated in the engine shown in Figure 1,
Figure 4 is'a cross sectional view on the line 4-4 of Figure 3, and, s Figure 5 is a sectional view on the line 55 of Figure 3.
Referring now to the drawings, the inven-' tion as an entirety as shown in Figure 3 is designated by A, and said invention may be associated with a device B. The device B 5 constitutes one form of air cleaner compris- 10 of a device which may be operated in one in- Application filed. October 26, 1928. Serial No. 815,318.
ing as it doesin the present instance a casing a having a mouth end 1 within which mouth end is placed blades 6. The casing is likewise provided with an outlet opening 2. Thus, ifair was received within the casing, it would be given a whirling motion by :the la'des b and the dirt and dust would be di rected against the end wall 3 of the casing and permitted toescape through the opening 2. I do not claim as anypart of my invention the casing per se as any form of air cleaning device might be utilized with the invention A. The invention A may or may; not be partially received within the casing.
In Figure 1,'the invention A is associated with the carburetor '0, which carburetor leads V 'to the intake manifold d of the internal cominfuser f and surrounding the member f is an infuser 9. For convenience, the infusers will be designated as first, second and third, with the infuser i as No. 1, infuser f as No. 2, and infuser g as No. 3. The infuser f is provided with a conical bore which flares near the mouth'there-of, as shown at 7. The infuser g is similarly constructed with the exceptionthat it-has a greater diameter than the diameter of the infuser f. The infuser f .1 is conveniently held within the mouth'portion of the infuser & by spaced webs 8 and webs 9 secured to the mouth of the infuser 4; hold the infuser. 9 forward of the mouth of the infuser 4. Thus, the construction is such that there is a spacing between theperipheryof the infuser g and the inner sur face of the bell of the infuser 4, as shown at 10, and there is likewise a spacing between the periphery of the infuser f and the inner surfacev of the infuser vg, as shown at 11. When the device A acts in conjunction with the aircleaner B, the periphery of the draft ventional form.
The operation, uses and advantages ofthe invention ust described are as follows:
We assume use of the invention with an internal combustion engine. It is evident that movement of the pistons creates a vac- V uum in the intake manifold, which in turn induces air flow through the carburetor so that an explosive mixture may be delivered to the engine cylinders. The advantage of performing what is known as supercharging is realized in the art,'and it is intended that the present invention should efficiently deliver a greater weight or volume of air to the carburetor. Furthermore, this greater weight ofair is delivered at alltimes in accordance with requirements and operating conditions of the engine. The use of the nozzle or infuser 7 acts to induce or cause cavitation. When the device is beingutilvized, streams of air flow through the path or spaces 10 and 11 and through the infuser or nozzle The infuser y will have a jet action as n16 air has the most direct path through the mouth thereof and the flow of J air which is induced bysome member tending to draw the air through the device takes the most direct path which would be through the'space 11. Thus, this flow would induce flow through the space 10. Air would likewise tend to be drawn through the infuser nozzle f and'the rapid passage of air around theinfuser nozzle would cause a:zone of low pressure or cavitation at thedischarge end of said infuser or roughly the zone marked 15. Thus, more air would beinduced to pass through the tube 6. It will be noted that this zone of cavitation occurs at thezone of least diameter of the tube 6 with thesaid tube enlarging as to diameter from said'restricted zone toward the tube 13. The result is that air streams aredrawn' at a rapid rate through the tube 6 and the rapid expansion which occurs allows greater weight or volume of air to be passed intothe internal combustion engine. There may be a vortex or whirling of the air stream as it'is passed Within the tube 6 due to the placement of the webs 8 and 9. In any event, a so-called squeezing action or compressive action occurs at the zone of least diameter of the tube 6.
Quite obviously a device of this character would operate upon any type offluid other than air.
It is important t'o note that this: device is streamwould be that included between the infusers f, g, and e or through the space 10 and the tertiary air stream would be that passed through the nozzle or infuser Any form of displacement apparatus adaptedto draw some fluid through the device A is contemplated by this invention.
It is obvious that various changesand modifications and variations may be made in practicing the invention in departure from the particular showing of the drawings without departing from the true spirit thereof.
I claim:
1. In a supercharger for internal combustion engines, a draft tube formed'with an infuser portion, a nozzle concentric within and spaced from said infuser'portion, and a-sec- 0nd infuser in axial alignment with and in part surrounding said nozzle andiin the zone ofthe first infuser.
2. In a supercharger for internal combustion engines, a draft tube, means for drawing a fluid through said drafttube, said'draft tube being formed with an infuser head, a
second infuser forward of the draft tube infuser head and in axial alignment therewith, and a nozzle concentrically confined'between the infuser head and the secondinfuser.
3. In asupercharger'for internal combustion engines, a draft tube formed with a flared mouthinfuser head, a second infuser formed'with a flared mouth forward of the draft tube infuser head and spaced inpart from the mouth thereof, and 'a' nozzle confined between the mouth portion of said 'infuser head and second infuser and spacedthe'refrom; said supercharger being adapted to have air drawn therethrough, the mouth portions'thereof being open to the surrounding all;
In testimony whereof, I have signed my name to this specification at Iios Angeles, California, this 7th day of-August, 1928.
