The actuating end defines a plug with a pair of O-rings attached thereto. The plug can be selectively positioned to: (1) block water entering the at least one inlet aperture; (2) permit fluid (i.e. water) communication between the at least one inlet aperture and the first outlet aperture; and (3) permit fluid communication between the at least one inlet aperture and the second outlet aperture.
Description
- Not Applicable.
- Not Applicable.
- The invention is a three-position diverter valve apparatus for use with home tub-shower systems.
- As noted in U.S. Pat. No. 5,193,582 there are various diverter valves known in the art.
- For example, the Grohe diverter valve includes a housing that has two inlets for hot and cold water respectively and a plurality of outlets communicating with the two inlet pipes by means of a cylindrical rotating seal means having alternate holes for communicating with the various outlet pipes of the diverter valve. In this invention, a generally cylindrical seal is rotated around a vertical axis. The vertically rising surface of the cylindrical seal means contains outlet holes for communicating the water from the inlet pipes with the outlet pipes. In this mechanism, the incoming water does not affect the position of the vertically rising cylindrical seal.
- Another example of a diverter valve is provided by Boccini which has a cylindrically rotating valve activated by a vertically movable piston.
- Whatever the merits of the prior art diverter valves there is a need for a diverter valve that enables a user to turn water off or on without first having to turn the hot and/or cold supply off or on, respectively.

rings rings annular grooves rings annular grooves rings rear end 180 ofstem member 120 and theinterior bore surface 310 ofbore 300 at therear end 280 ofbody member 140. - The O-
rings rings - During normal operation of the three-
position diverter valve 100 the operatingend 160 ofstem member 120 extends from thefront end 260 of thebody member 140. The operatingend 160 of thestem member 120 is adapted to receive and be rotated by handle H (shown, e.g., inFIG. 5 ). - By rotating the operating end 160 a user can select any of three operating positions wherein: (1) water is directed from the at least one

FIG. 2 shows an exploded view of the three-position diverter valve 100 shown inFIG. 1 . Explanations of the part numbers shown inFIG. 2 are found in Table 1, which is shown inFIG. 10 . -
FIG. 3 shows a lengthwise sectional view of the three-position diverter valve 100 shown inFIG. 1 . Explanations of the part numbers shown inFIG. 3 are found in Table 1, which is shown inFIG. 10 . -
FIGS. 4 and 5 show the three-position diverter valve 100 ofFIG. 1 in the off position. More specifically, water is blocked from entering themain body member 140 via the at least oneinlet aperture 320 when the plug 190 (not visible inFIGS. 4 and 5 , but shown in, e.g.,FIG. 3 ) is positioned alongsideinlet aperture 320 such that first O-ring 440 is positioned between the at least oneinlet aperture 320 and thefirst outlet aperture 340 and the second O-ring 460 is positioned between the at least oneinlet aperture 320 and thesecond outlet aperture 360. Explanation of the part numbers shown inFIGS. 4 and 5 are found in Table 1, which is shown inFIG. 10 . -
FIGS. 6 and 7 show the three-position diverter valve 100 ofFIG. 1 set to deliver water out of thefirst outlet aperture 340. More specifically, water can enter the at least oneinlet aperture 320 and thence travel to and exit from thefirst outlet aperture 340 when the plug 190 (not visible inFIGS. 6 and 7 , but shown in, e.g.,FIG. 3 ) and first and second O-rings end 160 between the at least oneinlet aperture 320 and thesecond outlet aperture 360 ofbody member 140. More specifically, water is blocked from traveling to and exiting from thesecond outlet aperture 360 whenplug 190 and first and second O-rings plug 190 are positioned between the at least oneinlet aperture 320 and thesecond outlet aperture 360 ofbody member 140. Explanation of the part numbers shown inFIGS. 6 and 7 are found in Table 1, which is shown inFIG. 10 . -
FIGS. 8 and 9 show the three-position diverter valve 100 ofFIG. 1 set to deliver water out of thesecond outlet aperture 360. More specifically, water can enter the at least oneinlet aperture 320 and thence travel to and exit out through thesecond outlet aperture 360 when plug 190 (not visible inFIGS. 8 and 9 , but shown in, e.g.,FIG. 3 ) and first and second O-rings plug 190 are both selectively positioned between the at least oneinlet aperture 320 and thefirst outlet aperture 340 ofbody member 140. More specifically, water is blocked from passing through thefirst outlet aperture 340 when theplug 190 and first and second O-rings inlet aperture 320 and thefirst outlet aperture 340 ofbody member 140. Explanation of the part numbers shown inFIGS. 8 and 9 are found in Table 1, which is shown inFIG. 10 . -
FIG. 10 shows a table listing part numbers. - The gap g (see
FIG. 11 ) between the first and secondannular grooves rings FIG. 12 ) such that by turning handle H the O-rings aperture 320 as shown inFIG. 5 . More specifically, first and second O-rings inlet aperture 320 andfirst outlet aperture 340, and between the at least oneaperture 320 and thesecond outlet aperture 360. Explanation of the part numbers shown inFIGS. 11 and 12 are found in Table 1, which is shown inFIG. 10 . - The invention being thus described, it will be evident that the same may be varied in many ways by a routineer in the applicable arts. Such variations are not to be regarded as a departure from the spirit and scope of the invention and all such modifications are intended to be included within the scope of the claims.
Claims (1)
1. A three-position diverter valve, comprising:
a stem member in the form of an elongated shaft having an external surface, an operating end and an actuating end, wherein the actuating end widens to form a plug of generally cylindrical shape, a portion of said external surface is lined with an external thread, said plug is provided with first and second annular grooves, said annular grooves circle said plug, said first and second annular grooves respectively accommodate first and second O-rings such that said O-rings circle said plug, wherein said first and second O-rings define a gap with a predetermined gap-distance interposed between said first and second O-rings; and
a body member having open front and rear ends, said body member comprising a hollow through bore interposed between said front and rear ends, said bore defines an interior bore surface, said body member defining at least one inlet aperture located proximate to the rear end of the body member, a first outlet aperture located at a point between the at least one inlet aperture and the front end of said body member, wherein the rear end of said body member defines a second outlet aperture, wherein a section of said interior bore surface defines an internal thread, wherein said at least one inlet aperture defines a width, wherein said gap-distance between said first and second O-rings is just greater than the width of said at least one inlet aperture, whereupon rotating the operating end of said stem member, the external thread of said stem member cooperatively engages with said internal thread on the internal surface of said through bore such that said stem member 120 can be selectively moved longitudinally back and for inside said bore thereby altering the position of said plug and said first and second O-rings such that the plug can selectively block fluid communication between said at least one inlet aperture and said first and second outlet apertures.
