Referring to the drawings by reference characters I have indicated .my improved regulator valve 'device generally at I0. As shown the device I0 includes .a base plate I2, 'a valve member I3 and a control member I4. 'I'he valve member I3 includes a bottom .portion I5, a top portion I6 andapartition member I1 between the topand bottom portions.

The bottom portion I5 is yhollow with a closed bottom andan open top and has a vtransverse partition I8 thereinyint'ermediate thel bottom and .topithereof andhas an inlet opening I9 -therein opening thereinto below the partition |16 and an outlet opening 2.0 therein opening thereinto above the partition I8. n l

The partition I8 has an aperture 2l therein which -adjacent the upper face of the partition includes a valve seatr portion22. The bottom portion i5 includes a plurality of integral downwardly extending legs 23 which are connected by va base ring 24 which is shown as secured to the base plate `I2 by a plurality ofV screws 2 5.

The topportion I6 is hollow with a closed top and an open. bottom and has a boss 26 extending from one side thereof. The boss 26` has a top end plug` valve recess 21 therein which opens into an lenlarged threaded aperture 28. which opens through the outer end of the boss. Furthermore the portion I6 at the topv thereof has a threaded vaperture 29 therein to receive an adjustable stop screw 2,9'.

The bottom portion I5, the partition I1 and the top Vvportion .I6 are shown as secured together by a plurality of bolts 30.

Within the top portion I6 I provide a piston 3l which includes a rod 32 positioned in an aperture v3 3 vin the partition I 1.. Adjacent .the lower end the rod 32 has a valve member 34 thereon which is adapted to engage the valve seat 22 to restrict passage through the aperture .2 I..

Positioned in the recess 21 of the boss 26 I pro- Vide a tapered plug valve .35 which includes Aa stem .portion 36. As shown the valvestem 36 is journaled in an `anti-friction bearing 31 mounted in .a yscrew plug 38 which is positioned in the threaded aperture28. Intermediate the screw `plug 38. and the plug valve. 3.5 in the threaded .aperture 28 I Yprovide asuitable packing gland 39 surrounding a portion of the Valve stem 3.6.

As shown `the ,plug valve 35 has a central chamber 4I] therein and two spaced side recesses 4I `and 42 therein (see Figs. 5, 8 and 9). The vtwo side recesses open through `the small end of the plug valve. Adjacent the large end of the plug and at one `side thecentral chamber 40 has two ports 43 and 44 opening therein.

.Opposite the port -43 the chamber .40 has a port 45 .opening thereinto. The valve recess 4I opposite the port 44 has a port46 opening thereinto. central chamber 40 has a port 41.opening thereinto and in yline `with thev port 41 the recess 42 has a port 48 opening thereinto. The boss 26 within `the top .portion I6 has an aperture .49 therein in line with the valve ports 41 and 481.

The .top portion I6 has a yconduit `5t therein one lend of which opens into ,the boss recess .21 between ythe bottom .thereof and the end of the plug valve 35. The opposite end-of the conduit .5,6 .communicates `with asimilar conduit 5l in the center partition I1 which in turn communivcates .withone end of a conduit 52 in the bottom P0rti0n.I,5. ATheopposite end ofthe conduit 52 .Adjacent vthe 4small end of the valve they conduit 53 communicates with one end of a conf duit 54 in' the parution I1. The opposite encor the conduit 54 opens through the top of the partition within the upper portion I6.

The upper portion I6 has still another conduit 55 therein which at one end opens into the valve recess 21 opposite the conduit 53 and in line with the valve ports 43 and 44. The opposite end of the conduit opens into'a chamber 56 inthe center partition I1.

The bottom portion I5 has a conduit 51 therein in line with the conduit 55 one end of which opens into the partition chamber 56 and the opposite end into the interior of the bottom portion I5 on thelow pressure side of the partition I8, that is above the partition I8. The bottom portion I5 has another conduit 58 therein one end of which opens into the partition chamber 56 and the opposite end communicates with a conduit 59 in the base plate I2.

From the foregoing it will be apparent that when the control valve 35 is in the position shown in Figs. 1, 3 and 5 wherein the valve port 41 registers with the conduit 49 and the valve port 44 registers with the conduit 55 an unrestricted passageway is provided from above the piston 3! through the conduits 49 and port 41 to the recess 46 and the port 44 and thence through the conlduit 55 and through the chamber 56 and the conduit 51 to the .low pressure side of the valve.

At the same time an unrestricted passageway is formed from the high pressure side of the valve through the conduits 52, 5I and 58 into the recess 21 and thence through the valve recess 4I and the port 46 and through the conduit 53 and 54 into the bottom portion I6 below the piston 3|. When the control valve 35 is in this position high pressure uid forces the piston upward until they valve 34 disengages its -associated seat 22.

When the control Valve 35 is in the position shown in Fig. 1 wherein the valve port 48 registers with .the conduit 49, the valve port 43 registers with the conduit r55 and the valve port 45 registers with the conduit 53 an unrestricted passageway is formed from below the piston 3I through the conduit 53 and the valve port 45 and 43 and the conduit 55 to the low pressure The control valve 35 is adapted to be actu-` ated by the operating member I4 which in turn is operated by either low or high pressure fluid from either station 18 or 19 of the base plate I2 which will be explained more fully hereinafter.`

As shown in Fig. 6 the operating member I4 includes ahollow lower portion 69, a hollow center portion 6I open at both ends and a hollow cap portion 62. The lower portion 60 is open at the top and has a closed bottom Wall 63 which is secured to the base plate I2 by a plurality of bolts 64. The lower end of the center portion 6I is threaded into the lower portion 6,0 as indicated at 65 and the upper end is threaded into the cap 62 as yindicated at 66. The upper end of the cap 62 is closed and has an aperture 61 therethru.

Positioned in the lower portion 68 I provide a frame 68 Which is shown` as held in position by 4the lower end of the center portion 6I.

Mounted in and suitably secured to the frame 68 I provide a Sylphon diaphragm 69. The bottom Wall 63 and the bottom of the frame 68 have an aperture 19 therethru which opens into the diaphragm 69. The diaphragm 69 includes an upwardly extending rod 1I on which a plate 12 is secured Yby a nut 13.

Positioned in the center portion 6I and the cap 'I 62 I provide a coiled springk 14 one end of which engages the plate v12 and the opposite end the upper wall of the cap 62. `The spring 14 resiliently urges the diaphragm 69 to a compressed position and the tension of the spring 14 maybe adjusted by either loosening or tightening the cap 62 on the center portion 6I.

Secured on the valve stem 36 I provide an operating member 15 which includes two oppositely extending arms 16 and 11. p As shown in Fig. 7 two stations indicated. at

18 and 19 provided on the base plate I2 forthel operating member I4. When the operating member I4 is to be actuated from the low pressure side of the valve I3 as. shown in the drawings it is located at the station 18 and when to be actuated from the high pressure side of thevalve I3 it is located at the station 19. Extending from the station 18 to the conduit 59 thebase I2 has an aperture 88 therein and from the station 19 to the conduit 59 the base has a conduit 8| therein.

When the operating member I4 is positioned at the station 18 as shown the conduit 8| is.

plugged and when the operating member I4 is positioned at the station,19 the conduit is plugged. The conduits 89 and 8| are adapted to register with the aperture 16 in the operating member I4.

When the operating member I4 is positioned at the low pressure station as shown in the drawings a rod 83 having one end universally connected as at 84 to the diaphragm rod 'II and the opposite end is universally connected as atL 85 to the arm 16 of the control valve actuating member V15. When the operating member is located at the station 19 the rod 83 is connected to the arm 11 of the control valve actuating member 15.

Mounted on the boss 26 I provide a collar 86 which includes an upper arm 81 which extends to a position above the arm 16 and a lower arm 88 which extends to a. position below the yarm 16. The upper arm 81 has a threaded aperture 89 therein to receive a bolt 98 which has a lock nut 9i thereon. The lower arm 88 has a threaded aperture 92 therein to receive a bolt 93 which hasy a lock nut 94 thereon. The bolts 90 and 93 are adapted to be set to adjust the limits of movement of the arm 16.

Extending outwardly from the collar 86 I provide an arm 95 having an apertured boss 96 thereon in a position above the plug valve operating member 15. Positioned in the boss 96 I provide a spring pressed plunger 91 the lower end of which is adapted to engage recessed portions 98 in the member 15. The tension on the plunger spring may be adjusted by a bolt 99 to restrict movement of the operating. member 36 until a .predetermined pressure is applied to the arm 16 or the arm 11deaisaoic the rod 83 is conupwards which in turn moves the valve 34 away from its associated seat in the manner previously described.

When the pressure on the low pressure side of the valve I3 builds up to a predetermined amount the pressure in the diaphragm 69 likewise increases and moves the diaphragm upward against the action of the spring 14 thereby moving the arm 16 vupward and rotating the control valve 35 to the position shown in Figs. 3 and 9 whereupon the high pressure iiuid moves the piston 3| downward as previously described.

When the operating member I4 is located at the station 19 the center partition`l1 is replaced by a center partition |00 as shown in Fig. 10. The partition |00 has a conduit IOI therein which connects the conduits 50 and 52 and a conduit |02 similar to the conduit 54 in the partition I1. Differing from the partition I1 the partition |00 has a conduit |03 therein which at one end communicates with the conduit 58 thereby providing a passageway from the high pressure side of the valve I3 to the operating member I4. Furthermore the partition |00 has a conduit |04 therein connecting the conduits 55 and 51.

When the operating member I4 is actuated from the low pressure side of the valve I3 the center therein which at one'end communicates with the conduit 55 and at the opposite end opens tothe atmosphere. Furthermore the partition |05 has a conduit |09 therein which connects the conduits 51 and 58. rThus when the partition |05 is used the iiuid which operates the piston 3| is exhausted to the atmosphere.

In Figs. 12 and 13 I have shown a partition I I 0 operatively assembled in the valve I3 to replace the partition I1. As shown in Fig. 12 the partition |I0 has a plurality of apertures III therethrough which form passageways from the lower portion I5 to the upper portion I6. The partition |I0 has a conduit II2 therein which connects the conduits 50 and 52 and a chamber ||3 therein into Whichthe conduits 55, 51 and 58 open similar to the partition I1. Differing from the partition I1 the partition |I0 does not include a conduit communicating with the conduit 53. In operation when the control valve 35 is operated to exhaust the pressure above the piston 3|, as previously described, the high pressure fluid acts against the valve 34 to unseat it. When the control valve 35 is operated to direct fluid to above the piston 3| as previously described the fluid below the piston 3| is exhausted through the apertures III in the partition IIO.

In Fig. 14 I have shown a partition |I4 to replace the partition ||0 when the operating member I4 is operated from the high side of the valve I3. The partition II4 has a conduit II5 therein connecting the conduits 50 and 52 and has a conduit i I5 connecting the conduits I I5 and the conduit 58. Another conduit |I1 in the partition I I4 connects the conduits 55 and 51 and like the partition IIO the partition II4 does not include a conduit communicating with the conduit 53. From the foregoing description it will be apparent that I have provided a novel automatically controlled regulating valve device which may be operated in various manners and which is simple in construction and is highly eicient in use.
