FLUSH-VALVE.
Specification of Letters Patent.
Patented June 18, 1918;
Application filed March 8, 1915. Serial No. 13,046.
To all whom it may concern:
Be it known thatI, GREGOR KUNTNY, a subject of the Emperor of Germany, residing at Trenton, county of Mercer, and State of New Jersey, have invented certain new and useful Improvements in Flush-Valves, fully described and represented in the following specification and the accompanying drawings, forming a art of the same.
This invention re ates particularly to valves of that class for flushing water closets and the like and commonly known as flush valves, but the valve of the present invention may be used also for other purposes.
The especial object of the invention is to provide a flush valve that shall be simple and cheap to manufacture, and in which leakage and the necessity for pacln'ng the operating valve stem or other parts, shall be avoided as far as possible, and the parts requiring repair or renewal be readily accessible.
In the accompanying drawing forming a part of this specification there is shown, for the purpose of illustration, a flush valve involving all the features of the*invention in their preferred form, and this flush valve will now be described in detail and the features forming the invention then specifically pointed out in the claims.
In the drawing, which shows the flush valve in central section, A is the casing, preferably formed in one piece, as shown, and divided by partition 10 into an inlet chamber and a discharge chamber, B, C, being, respectively, the inlet and discharge spuds screw threaded for connection to the supply and discharge pipes, as usual.
On one side of the casin A are arranged the main supply port 11, t e discharge port 12, timing port 13, and relief chamber discharge port 14, and this side of the casing and these ports are covered by a diaphragm 15 which controls the main supply and discharge ports 11, 12, but is open opposite the timin and relief discharge ports 13, 14 to permit the free passa e of liquid through these ports. The diap agm 15 is clamped between the side of the casing A and plate 16, which late is shaped to rovide a pressure cham r 17 outside diap ra 15, and has relief port 18 through the p ate. Outside theplate 16 is a second dia hragm 20, coverin relief discharge chamber 19 between p ate 16 and the diaphragm, and con trolling relief port 18, whichis clamped be tween plate 16 and cover plate 21, so as to completely close the side of the flush valve casing and prevent leakage at this side. Cover plate 21 has a hollow stem-22 projecting outward therefrom, in which is a plunger 23 carried by stem 24 spring pressed by spring 25 against diaphragm 20 to normall close relief port 18, and the stem 24 carrles pin 1 passing through a rectangular slot 2 in operating handle 26, which handle is preferably mounted, as shown, so as to be rocked in either outward or inward direction, and on either movement to move the plunger 23 outward against spring 25 and permit diaphragm 20 to move outward to open relief port 18. Plate 21, with the diaphragms and plate 16, are secured to the casing b bolts 3, preferably four in number, so that t e plate 21, with handle 26, may be turned to any quarter, and thus the handle 26 lie conveniently according to the mounting of the flush valve. The relief discharge chamber 19 discharges through port 4 and the opening in diaphragm 15, to port 14 and the discharge chamber in casing A. The
main port 11 is controlled by diaphragm 15, which preferably has thereon, and integral therewith, a cone-shaped projection 5, serving as a refilling cone, to allow a small flow of water for filling the bowl just before the supply is fully shut ofl, and a removable perforated plate 6 is preferably inserted as a seat for the diaphragm 15 outside the main port. This perforated plate not only acts to support the diaphragm in theclosed posi tion, but by substituting plates differently perforated, the discharge through port 12 may be regulated as desired. The timing port 13 extendin from the supply chamber to the pressure ciamber 17 is controlled by timin valve 7, shown as a common screw threa ed needle valve, suitably packed in casing A. The valve as thus far described may be used without any shut-off or flowregulating valve in casing A, the perforated plate 6 bein relied on for regplating the flow, but pre erably a valve will be used by which the flow ma be entirely out 01f or regulated as desire and the shut-off valve and port is preferably arranged so that the adjustment of the shut-01f valve does not affect the flow through the timing port 13. As shown, the inlet chamber is divided by a partition 27, having a port 28, and this port is controlled by a valve 29, shown as an ordinaryscrew valve carried by'a valve plug 30 screwed into casing A and having the valve stem suitably packed. It will be understood, however, thatthe form of this shut-off valve is not essential.
The operation of the valve will be understood from a brief description in connection with the drawings. The valve is operated for flushing, by pressing the handle 26 either inward or outward, which withdraws the plunger 23 against spring 25, thus releasing the diaphragm 20 so that the pressure in chamber 17 forces this diaphragm outward and opens relief port 18 from which the water in chamber 17 flows outward to the discharge through chamber 19 and ports 4 and 14. The pressure on diaphragm 15 pressing it inward to close port 11 thus being relieved, the pressure of the water from supply B in the inlet chamber forces the diaphragm 15 outward, opening the main port 11, and the water then flows from this port through the discharge port 12 to discharge C. The handle .26 being released, spring 25 forces the plunger 23 inward, pressing diaphragm 20 against plate 16 so as to close the relief port 18, and the pressure chamber-17 is then filled up again by water flowing slowly through the timing port 13 under control of valve 7 at a rate adjusted by the valve, so as to secure the length of flushing action desired. When full fluid pressure in the chamber 17 is secured, the excess pressure on this side of the diaphragm 15 presses the diaphragm inward to close the main port 11, the port being first nearly closed by the entrance of the refilling cone' 5, and then a small flow being permitted by the cone for refilling the bowl, until the diaphragm is fully seated. If it be desired to adjust or shut off the flow, this may be done by shut-off valve 29, without interfering with the timing action of port 13 and valve 7 as these are on the inlet or pressure side of the shut-01f valve.
It will be seen that the flush valve construction shown has many advantages, some of the more important of which are as follows: The necessity for packing the operating plunger or its stem, and the liability to leakage upon this side of the flush valve, are entirely avoided by the diaphragm outside the relief port and relief discharge chamber, and the operating plunger and its spring are fully protected from the water so that no dirt or sediment carried. in the water can clog or interfere with the operation of the plunger or its spring. This diaphragm, also, reduces the transverse dimensions as comared with other relief valves, so that a onger spring can be used on the plunger than within the dimensions of usual constructions. With the main diaphragm, also, and the intermediate plate 16 forming the pressure chamber, no packing is necessary,
phragm,'increasing the durability of the latter. The perforated plate over the discharge port not only supports the diaphragm,
but by being made removable, dilferent plates may be used according to the pressure, and thus a regulating action be secured. By placing the timing port and valve 7 on the inlet side of the shut-off and regulating valve 29 the action of the timin port is not afiected by regulation of the ow through the main valve.
It will be understood that the invention is not limited to the exact construction and arrangement of parts shown, but that many modifications may be made therein while retaining the invention defined by the claims. What is claimed is:
1. A flush valve having a casing provided on one side with a main inlet port and a main discharge port, a regulating valve and port on the inlet side of the main inlet port, a timing port and valve on the inlet side of the regulating valve, a diaphragm extending over the port side of the casing and controlling the main ports, a plate outside the diaphragm forming a pressure chamber between it and the diaphragm and connecting with the timing port, a relief port in the plate, a diaphragm seating on the plate and forming a relief valve controllin the relief port, a cover outside the relief port diaphragm, and an operating member carried by the cover for controlling the diaphragm to open and close the relief port.
