AUTOMATIC REGULATNGVALYE Specification o Leters Patent.

rammed ree. 17, 191i..

`ppiicaton led March 25, lA Serial No, Lie-.6537f To'all 'whom tmf/,y concern Be it known that I, CLARENCE B` Roon-ne,

citizen ofhe United. States, residing at Seattle, in the. county of King end Stute or Vashingtoin have invented eertein new Automeile Re0u1at1nff-Vaives., of which the foiewine and useful Improvement; in

`lvis a speciiicetion.

My inve'nion reieies to 'iileprevernenzs in regulating valves that nre adapted suitematically to regulate the eapneiy of e, pessageway for fluids, as for instance, ihe paesagewey that extends between the enrbnreter and the intake cylinder pore ef an internal combustion engine, :ind vthe object of my iinprovement is to provide e simple sind inexpensive valve which is adapted io be connec-ted between the entrance ports of n .e engine cylinder and the eerbureier iff-,emot

and which may serve in such position antw matiealiy to very the cross eetionel aren. of its valve eontroiled opening in response to 'Variations in the pressure exerted on the valve in an invvar-'lly direction due to the 2'5 suction produced by the @isi-on of the. engine by which suction the enplosive mixture of gas and zur is drawn from ihe eeronreter into the cylinder, and which may serve more thorouhl7 to mix the com )orient ,erts of b i theinlowlng gaseous mixture, and e further object of my improvement. is to provide in such structure eseatless valve that. simil require no grinding in the operation of r'iting; it to its normally Closed position and which may not easily7 be obstructed in its action.

I attain these objects by devices illustrated in the accompanying drawings, wherein-- Figure l illustrates. one forni of n valve embodying my invention 1oy a view in iongi- 40 tudinal Inid-seeion wherein Sonie movable 3 illustrates by e View in end elevation a de tail of the structure shown in. Fi f Lilie ,reference numerals indiezi'e like parts throughout the drawings.

Referring' to the drawings, 4e is u veive casing, preferably of cast brass, of' a forni Somewhat .like en elbow provided, with e pipe-thread 5 et one of iis end openings rnd a pipe-tiiread 6 :it iis other end opening, che pipe-threads 5 and (i bein?r zidepted o con `neet the valve `with e eeroureier und Wiih the Cylinder of engine Coneenrirniiy disposed lengthwise within longer por -on of the casing #i is a mourned freely to more end- :ef-,ing being` supported ,ri disposedone Within d mijecen to the pipenher within en adjustable eve i) in 4,he opposite end fion of the easing 4, es

ixrdiy 'ilvestenl 7 and l u f.; r-vnive i2 Whose is rounded and Whose snel; as may Closely fit but freelyVv move through the eonstrietecl passageway formed by the ridge l1, thus., if he di in normal position to regg' ridge l1, rhen in suoli ense the een@ iirongh the structure would be 'ne-.led io the passage of any considerable immuni of explosive mixture, but if the di gevelve 12 be moved in either direc h normal position the pas il wil be enlarged. A, .spin n 1" Minnie slrengli ie disposed io sorrmznd he vzilvesteln 7 tvo eX tend between he disk-valve 12 and the ,spider while another spiral Spring 14- is disposed osnrround SuidV valve-stein 7 to extend between ilielevnlve 12 and the inner end Surface oi screw-threaded sleeve 9, wh "eby when said sleeve 9 is turned to screw inwardly the spring M may force the dish-valve inf 'toward the spid S against the force of the spring i3, whiie if the said sleeve O is turned to screw ontfvnrdly iiorelieve. the emiipression of the si v'ing' 14 then the spring l'S will not to nieve the dislevelve l2 toward the seid sleeve i?, thus Yby manipulation of said seiev-flnee,cled sleeve 9 ille dislevalve l2 muy be set in any iengiindinel position with respect. te he constriction foi-ined by the ridge l1, l

' in ope its valve-stem 7 to move,

i re

ing i'aririllons in the extent of the movement ot' the disk-valve 12 from the `position al: which it is normally set withrespect to the ridge ll by the manipulation ,of the screwthreaded sleeve 9.. For inst-ance, a high piston speed would cause the disk-valve to more farther to enlarge the passageway through the ridge 11 to a greater capacity than would a low piston speed; and the explosive mixture in its passage through the annular opening;f lietweenthe disk-valve 12 and the inner surface of the easing 4, thus would automatically vary the amount-of air and gas in the explosive mixture from the earliureter to the intake ports of the cylinder, and `further if hy accident the explosive mixture. within the space between the disk-valve l2 and the cylinder ports be ignited then `the resultant. explosion -ivould merely kiek the dislovalve 12, toward the serew-tlireaded sleeve 9 to open wide the aniiular passageway through which passageYYY way the find exit.

In Fig'. l l have shown the inner surface of the ridge 11 as rounded hy a eirele of small radius whereby a longitudinal Inoveiiieiit radiply eiilarges the passageway but products of suc-li explosion "eould 'in Fig. 2,1 have shown a iiiuch wider ridge l5 tapering from either side to the center thereof whereby a movement of the diskvalve 12 causes a more gradual enlargement of the' passageway through the constricted portion of the structure.

In Fig. 3 I have shown the form of' the Y spider 8 as it would` appear when looking,r

into the structure at the end providedwit-h the pipe-thread 5. l

Obviously various changes and modifica-v tions may be madein form and dimensions of ldii'erent-v1iarts of my invention without departing from the spirit thereof.

\Vhat I claim ist" In a regulating valve 'of the class described, the combination .with a valvecasing provided with iniet and outlet openings and a passageway extending between such openings, said passageway being eonstricted .in its diameter in one portion of its length, or a disl-i'al\'e member provided with a. valve stein that projects froqiyeech side thereof in a position that is eono'entrie therewith, guide l hearings for saidyalve-stem associated with said salve-easing and' disposed to support and guide s aid valve-stein in its endwise nioieinents so that said disk-valve member portion of sfiidpassageway in a position eoneeiitrie therewith, one of said bearingsV being supported by a spider at a point near one ot' said lopenings of said `vpassageway while the other of said bearings comprises a .sleeve which isrrprovided with an external sereiv-t'hr'ead that adapts said sleeve to be adjustahly disposedivithin a screw-threaded hole in tli'ef'wall of Said passageway, and tivo spiral compression springs each disposed to .surround said 'valve-stem and eX- tend between one side" of said disk-valve ineiiiher and the end surface of one of ysaid valve-stein guide bearings whereby said '.lsk-ialve member may be disposed in a desired'iiornial lengthwise positionV with re-Y spect to said restricted portion of said pas.

.sageiray in response to the manual adjust nient of said sereivthreaded sleeve that coinprises said one ot' said juide bearings.

In \\'itn`ess-\'vliereof, hereunto subscribe my name this tenth day of March A. D., 1919.
