Figure 9 is a sectional view 'taken las on a line V9--9 of Figure 8.
Referring more particularly to the drawings, there is illustrated by -way of example, 'but -not of limitation, a control valve,'generally Adesignated by the numeral 20, secured in any conventional rnanner to aflexible rubber hose 22, as by set .screws 23 :provided Ain .any desired number therearound;
The valve 20 preferably .comprises a 'body A `25 of cylindrical form including a plug 26 secured within "the body as by `set screws k2'l. The plug 2s is threaded as at 2a J@permitirle axial threaded insertion of a complementarily threaded nozzle 30 formed as' with raised'male threads3l The body'25 of the valve is fitted Vwith a preferably.replaceable'rubber lining "33which makes a tight fit around its circumferential periphery 34 with `the innerwalls 35 of `the body v25.
Theliner 33 is formed as with a rearwardly extending portion 36 communicating directly with the interior 31 ofthe hose `or the like 22 and a preferably forwardlyrextending portionBB. At its'forward end 39 the liner vis most desirably stepped and abuts a rubber collar 40 formed separately therefrom for convenience of manufacture, said collar having a rearwardly directed annular'preferablyaredcavity 42 for the receipt of the rearmost portion 43 of the nozzle v30. The collar 40 is Huid tight around the nozzle portion 43V andV is shaped 'to promote the/least amount of 'fluid friction.v
The liner 33 includes, integrally therewith, a exible diaphragm 44 including central solidportions 45, 48 and axially directed ports 4:6 of suitable hydrodynamic shape communicating between the rearward and forward sides of the `valve. Said ports 46'are preferably uniformly distributed'circumferentially ofthe axis ofthe lvalve,
and arejof any deslred'shape'preferably to koffer 4 pair or replacement. But particularly the ring 40 and the liner 36 may be axially withdrawn from the body 25 as through removal of the valve from its connection with the hose 22 or by removal of the plug 26 and thereby replaced when worn.
In the embodiment of Figures and 6 a valve generally designated at |00 may be threadedly or otherwise secured to hoses` o r pipes |01 and |02 connected to a source andoutletrespectively of air, Water," oil, or other uid carrying'suspended material such as sand, grit, dirt, or the like.
wherein the valve is closed (c. f., Figures l and The normal fluid pressure from the hose l'2'2 Y against the back Side of the diaphragm'V distorts or flexes the diaphragm as at 55 forwardly (Figure 2) causing the same to seat against the end 43 of the nozzle. The normal unflexed position of the-diaphragm is shown in Figure 3. `Theresilient forces within the diaphragmresisting de- VIiection lcause the same to snap closedsuddenly against the end 43 of the nozzlezwhen lthe 'dia-V phragm is moved close tothe end 54 of thenozzle..vl The valve is also suddenly opened y(' i. e., with -a snap?) .releasing the full force of the sand blast as the nozzle is moved axiallyiaway from the diaphragm, asbyY unthreading movement of .the nozzle. j
" w i In the above described snap action of the diaphragm when the nozzle 30` is axially. moved Within the body relative to the diaphragm, a
point is reached inwhich the diaphragm suddenly snaps closed against theA end 54 of the'nozzle. Such snap action is eiected instantaneously so that the full blast is suddenly :released or it is equally suddenly stopped'.` No dribbling of sand and/or Water or other conveyed material there by-occurs. .Y
The pathnof the` blastA is from the-:hose 22 through the end portion' 36 of the "liner 33, .the ports 4B, the annular tapered surge "chamber 51,
through Athe tapered openingv Eiland bore1z5| of the nozzle. 1

Furthermore, a nozzle containing a-differentsized bore may be substituted'. In this manner, the nozzle which tends to be eroded internally usually prior to the wearing out of the other parts,
Jparticularly the body 25; may Sbe replaced without discarding -the relatively unwornbala'nce-of thevalvel -V l '1- #The plu'g 26Amay-:beremovefd throughjremo'val 'of the set Vscrews 2l fwhereupon .the liner' 33 may 'be axiallywithdrawn fronrthe' body'25for`re'- The valve ibody |03 maybe substantially globeshaped. A stem |04 may be threadedly or slidablyV inserted as through a bore |05 (threaded as shown), formed in the body |03 and axially i manipulatable asby a handle |06 of a threaded type or of a quick-acting or lever type. By a ball and socket or equivalent connection |01, axial movement of the stemf' |84 may be transmitted -.through core- |||8 to a rubber diaphragmA |09 'formed integral with a liner l'l. The diaphragm |09 can include a forwardly directed tapered valve portion .havingr a preferably fluted exterior surface U2 Vadapted to be compressed in seating against ancannular seat ||3.formed as by a tapered bore H4 in the end-` I 5 of the outlet pipe H6.; The pipe H8 and the pipe |02 may be integral or may be formedof separateportions so that the pipe ||6 is a replaceable insertior the valve.' Also, the seat||3`and-diaphragm IHl!) may -be set at an angle relative to the ,axisk o f the valve corresponding to that of the stem |04 so that suchstem is approximately normalto the plane vof the. diaphragm andseat and is Aaxially related to them.V l v Thefow --of `iiuid containingsuspended material is through the pipe |0| into the interior |8'of the valvebody |03 provided with its preferably replaceable rubber; lines Uil, :thence through ports H9 in the liner to the-forward side of the diaphragm which may in partform an annular surge cham-ber V|29l whence the `material .is passed through the pipe I6 -between the seat I4 and the tapered .valve element of deformable rubberor similar material H2; Y- l f' The valve may be forcibly closed against suspended material carried Iby the fluid-Without injuryto the valve or its parts. The uted corelike valveportion H2,` being capable of compression, is smashed against the seat |3. Due to the lining and integral diaphragm construction Whichis resistant tovcerosion, the valve possesses ,a particularly long life and high service quali- .ties andis adapted for use in sand blasting as well as for conducting other fluids containing suspended matter. The fluted arrangement of the cone-.shaped `seat I|2v facilitates the break- Aing .away thereof from the seat-annulusl ||.1|.V

i The end |65 of the nozzle is adjustable, asby vthreading at -|1|, for extension from the main body of the nozzle |54, in order to :control the nat-ure of the emitted stream.
lThus a spray may be had, or a relatively heavy stream by adjusting the end |66 relative to the end |65 of the rod, the volume being separately .controlled by axial adjustment of the main nozzle body as by the threads |56, |51.
For abrasive materials carried in the uid, a linei` as of tungsten carbide |12 is providedwithin the bore |13 of the nozzle.
^ As heretofore explained, the replaceable rubber liner |53 minimizes the'erosion due to abrasive action within the body |5| of the valve. The nozzle |54, including the end or tipv |66, the .liner |53, and the valve body |5|, as well as the rod |63, are replaceable.
In the embodiment of Figure 8 the valve 200 comprises a body .20|, a forward plug .202 keyed thereto as by screws 263, a nozzle 204 axially threadable within the plug 202 and arubber liner 205. I
The rubber liner comprises abody portion 20S and a diaphragm 201 formed with a passageway 208 defining an oriiice 209 connected withra hose 2|0-leading as to a source of water. y
The nozzle 204 may be constructed as inthe previous embodiments, particularly as inthe .embodiment of VFigures 1 through 4 and is similarly adapted to engage against the diaphragm 2.01 or the cone-shaped forward projection 2|| thereof as and for a valve or regulating mechanism, with or without snap action. Y
The incoming iiuid `through the hose 2li) may be adjusted as by a needle or other yvalve 2 2 from which it is directed under pressure through the orifice 209 vinto the bore 2|3 of the nozzle 204. Thus it may readily be picked up by the :incoming relatively dry air and sand customarily delivered by the hose 2|4. vSuch dry vsand, .and air is fed through .ports 2 6 formed in the .diaphragm 201,- such ports being relatively tapered inwardly and forwardly to provideA amore direct and streamlined passage for the dry 'ingredients from the hose 2|4 to the nozzle 204, thereby practically omitting the surge chamber provided in the-.other y mingling of the 'dry *and wetingredients-glancecasioned, and the resultant valvaiswell adapted for use as a dry blast orwetvblastrcontrol.
It may be notedthat the radially-inserted injector .pipe 22llgincludingthe axiallydirectedex- `tension thereof .22| ,leading tothe orifice-209 Would,.if madeof metal or otherinexibl'e-.material, prevent the axial movement or deformation of the diaphragm for the snap-actionopening and-closing of the valve as aforesaid.; jTherefore, .if the snap action be desired in the vinstant valve, the passageway-208 may be formedzdreotly in the kdiaphragm 201 orsaid passageway .may be lined'wi'th anexible metalconduitor with a ilexible sheath 'of yrubberof ,the like materials Pref'- :erably -thezopening 2G49` vshould be-fairly fwell formed of .relatively hard stockto improve its function as an orifice.y
"The nozzle 204 .may have a removable `tip-226 which together with the main body-221 of.: the nozzle comprise va holder vor chamber for the confinement of a: plurality` of annular bodies or washers, as 4of plastid-228 positioned 'in abutting coaxial relationship .too-ne :another within'the nozzle 225. The .first 'of Vsucl"1.;bodies 228 iis held .nrmlyagainst axial movement bymeans of the shoulder ZZSfOrmedinthe-tip 226 of the nozzle while the rearmostzofisuch washers 230 is like,- wisefclamped and firmly held by vmeans of the annular shoulder 23| formed adjacent thenozzle inlet 232. The bodies 228 may be formedas annuli or as radiallyseparated liner segments.

While turbulence of the iiuid passing through the ports formed in the .diaphragmgof the various embodiments of the valves hereindescribed is sometimes desirable, it is of equal andl .probably greater -importance to avoid suchv turbulence; as would drive theparticles suspended tothe incoming-fluid laterally against theyinterior ofthe nozzle or pipe, comprisingfthe vvalve outlet. Since suchl lateral movement tends: to vcauser undue erosion vof thel interior :of the nozzlefor outlet vpix-pe, the degree of turbulence can beiregulatedtod-a .large extent by appropriate streamlining of the `cones formed -upon the inletor outlet side ofthe diaphragm, or both. Likewise, the size andrlshape of the ports through the diaphragm, .including the intervening diaphragm materialbetween ports, is -of importance and is oftenvcritical in achieving an optimumA vstreamlineda11d1.1neb- -structed passage ofY the uid, such .asV .ai-r .fand sand. n 1 1* The form vand constructionbf the various nozzles and youtlet .pipe herein illustrated anddel scribed are not intendedl to relater-only' tothe Aparticular embodimentv in which they awshown but may -to a large extent bevrenderedvinterchangeable through modification withimthe skill of one familiar with theart of valve construction..r r
This invention features the-proViSQIlfpf-,fa new and improved valve suitable forcontrolling, stop*- ping and starting the -flowfof. a Vfluid .containing abrasive orother suspended foreigny matter.- It likewise features the provision of. a perforated preferably flexible diaphragm. having a -solidj .cen- ,ter axially. disposed in a conduit-.ha'ving anend seatable Vagainst the solid center of the diaphragm as .and 'for thel valve rmeans per'gse,fthe conduit being axially adjustable. It likewiseffeaturesgthe provision of .a diaphragm having `an optionally adjustable-preferably snap action for instantaneously turning on and shutting oi the full force of the desired uid stream. In addition, the invention features the provision of a new and improved axially disposed liquid injector of maximumeilectiveness, an optional cone-shaped substantially streamlined central diaphragm portion, and replaceable rubber or hardened parts or `the like.
