REGNELL REGULATING DEVICE APPLIED TO FLUSH VALVES Filed March 22, 1955 Patented Aug. 6, 1940 REGULATING DEVICE APPLiED To FLUSH VALVE l f Yngve Regnell, Stockholm, Sweden y y Application March 22, 1935', seri'aifv @10511468 Inl Sweden March '7,193'37- 2 Claims. (C12. isi-93')l 'Y kThis invention relates to a device for regulating thewater or fluid flow in flush valves or in apparatus of similar nature. In order to regulate or change the water flow, which is wanted to pass through the flush valve is generally has been necessary tofremove the cap or other parts of the ush Valve to be able to make the necessary changes on the regulating part or partsof the apparatus. 1

The object of the invention is'to provideade- Vice whereby the water or fluid flow'through flush valves or similar apparatus can be regulated from the outside of the apparatus. The object is obtained by a device, which makes it possible to change from the outside the reciprocable position of the regulating parts in the apparatus, so that the water or fluid flow, leaving the apparatus, can be regulated to desired measure without dismounting or removing any parts of the apparatus whatever.

In the accompanying drawing Fig. l shows a sectio-n of a flush valve with the regulating device connected to the push lever, Fig. 2 and Fig. 3 are sections showing various constructions of the regulating device connected to the push lever.

In Fig. l is shown the valve casing I and a diaphragm 2, which is tightly pressed to the valve casing by the cover 3. The valve body 4 is by a lock device 5 securely fastened to the diaphragm 2. In the valve body 4 is a channel 6,

through which the chambers above and below the diaphragm 2 communicate. Below the valve body 4 Aand connected thereto is a guided part 'l of the main valve, which keeps in place a gasket 8 of rubber or the like, which tightens against a seat 9. In the valve body 4 is placed an auxiliary valve I0, which tightens against a seat II. On the stem I2, is placed a socketed member I3, which can slide on the stem. The member I3 is prevented from falling down by a shoulder I4 on the stem I2. The member I3 can be operated by a push lever I5, which is slidably tted in a. casing I6, inset in the valve casing I in such a way, that the push lever I5 itself or together with the casing I6 can be moved in diiTerent positions and be locked in desired position by means of a screw I1 and a groove`2 I By unlocking the screw I1 and turning the casing I6, connected with the push lever I5 an eccentric disk IB will give different connection spaces to the socket I3 and thus regulate the water flow by operating on the inside regulating parts of the apparatus. On the inner end of the push lever I5 is attached the eccentric disk I8. Even so the casing I6 or other parts, Lthat guide the `push lever, can'beeccentrically `formed. n The push lever I5 is kept t'o its outside position through' a spring 4I9 and is prevented fromgturn-g ingy aroun'din the casing( I6 by a'pin 20.

2 is4 shown another design, where the push lever 2I isfarr'anged Iin a casing22 with a ball-'formed shoulder, whichV by an yoverlap 23 is tightened againstthe valve casing I. By loosening thebo'lts 24`the push lever can be `turned in different axial positions andiafterwards locked injthe desired `position by tightening the bolts.

" Inthe design shownr in Fig. 3 `tl'ieadjustment of the push lever is obtained by loosening `the mi bolts 26 and pushingthe casing IB, movable in the spare spaces 21 and 2'Ia upwards or downwards, whereby different connection spaces and the desired water flow regulation are obtained.

When the water passes into the valve through the inlet 25, the chamber below the diaphragm 2 is filled with water and through the channel 6 is the chamber above the diaphragm lled with water. As the pressure area on the top side of the diaphragm is larger than the area on the underside, the valve is kept closed by means of the water pressure. By pushing in the push lever I5, the eccentric disk I8 operates on the socket I3 appplied on the auxiliary valve stem I2, so that the auxiliary valve IIJ is tilted to open position, whereupon a part of the water from the chamber above the diaphragm 2 runs away. The

. valve body 4 is now lifted by the higher pressure on the under side of the diaphragm, and the water is allowed to flow through the valve. When the valve body 4 is lifted, will at the same time the auxiliary valve I and stem I2 together with the member I3 be lifted. When the main valve 1 is lifted to such a position, that the lowest edge of the member I3'has passed the eccentric disk I8, the auxiliary valve I0 returns toits original position. The chamber above the diaphragm rells gradually through the channel 6 and the main Valve will be closed by the regained pressure on the top of the diaphragm. If the push lever I is held in its inward position the member I3 will abut the eccentric disky I8 and the stem I2 will slide down, by which arrangement the auxiliary valve I0 will be kept closed.

The longer time the auxiliary valve will be kept open by the push levers operating on the auxiliary valve, the more water will be allowed to pass out of the chamber above the diaphragm, and the longer time it will take before this chamber will be refilled and the main Valve again will be closed. Naturally the auxiliary valve must be opened to such a degree, that a larger amount of water will be allowed to ilow out therethrough than into the chamber above the diaphragm through the channel 6.

By turning the casing I6 and operating the push lever, dierent parts of the eccentric disk I8 will be brought in contact with the socket I3, by which the valve body 4 must be kept open a longer or shorter time, before the auxiliarylvalve closes. This time can be varied between the limits, which are controlled by the eccentricity of the disk I8 in such a manner, that if the extreme part of the eccentric disk I8 touches the socket I3, the time for the Water flow will bea maximum, and if the lowest part of the same disk touches the socket, the water flow Will be a minimum. By turning the-casingIS in different intermediate positions the Water ow can-be adjusted at will. The same result will be obf tained, if the push lever is eccentrically located in the casing I6. The same result is obtained by various modications as shown in Fig. 2 and Fig. 3, the means of regulating beingas described above. By using a regulating device according to this invention, the water flow in ilush valves can be regulated from the outside in ,shortest possible time by using a screw-driver.

Another advantage is that, if the Wanted water flo-w is not obtained bythe rst regulation a smaller adjustment can immediately be done.

The invention claimed is:

1. A valve device comprising two valves, oneva main valve, which controls the water flow, the

other an auxiliary valve for controlling the main valve, a depending laterally movable stem for controlling said auxiliary valve, a casing enclosing said valves and stem, a push rod mounted in a tubular guiding member extending into said casing for engaging said stem so as to move it laterally to open the auxiliary valve, and means for attaching said tubular member to the casing so that it can be angularly adjusted, whereby the push rod contacts the auxiliary valve stem at different distances from the end thereof.

2. A valve device comprising two Valves, one a main Valve which controls the water flow, the

other an auxiliary valve for controlling the main valve, a depending laterally movable stem for controlling said auxiliary valve, a casing enclosing said valves and-stem, a push rod mounted in a tubular guiding member extending into said casinlg so that the inner end of said push rod is adjacent the end of said stem and may be moved into contact therewith for actuating said auxiliary valve, said tubular member, where it passes through the casing, having a spherical surface formed thereon, said casing having a corresponding surface, whereby the tubular member and push rod may be angularly adjusted with relation to the auxiliary valve stem, thereby varying the time of closing of the auxiliary valve as the push rod contacts the stem at diierent distances from the end thereof, and means for retaining said 3Q tubular member in adjusted position.
