Definitions
- This invention relates to diverter valves and, more particularly, to diverter valves for directing fluid either to a tub spout or showerhead.
- Diverter valves are commonly used in tub spout assemblies and are usually located in a separate housing connected to a single handle valve or interposed between hot and cold water valves above the tub spout. These diverter valves are typically constructed to have two effective positions: In a first position, the diverter valve permits water to pass only up through the shower riser and out through the shower head. In a second position, the diverter valve permits water to pass only through the tub spout. Some diverter valves seal off the conduit leading to the tub spout in the first position and seal off the conduit leading to the shower riser in the second position.
- diverter valve designs include a user-operable valve stem coaxially connected to the center of ceramic valve members, which stem connection severely restricts flow cross section within the valve, or requires a larger diverter valve housing to provide adequate flow.
- a conventional diverter valves by such a diverter valve design including ceramic disks is not possible because the size of the diverter valve housing would need to be enlarged to provide adequate water flow.
- What is needed in the art is a diverter valve that is reliable and fully seals the tub spout conduit or the shower riser and minimizes or eliminates excess noise from the water flow without the use of a vacuum breaker, and further serves as a field replacement for conventional diverter valves without compromising water flow or requiring modifications to the diverter valve housing.
- a first embodiment of a diverter valve assembly includes first and second rotatable valve disks and first and second stationary valve disks mounted in a valve chamber.

- the slot includes opposed ends forming stops for the pin, whereby rotation of the stem is limited.
- the stem includes a pin extending perpendicular to the stem and the valve housing includes a semi-cylindrical extension about the opening.
- the extension includes diametrically opposed surfaces forming stops for the pin, whereby rotation of the valve assembly is limited.
- a disk positions is defined by each step.
- the first disk is position characterized by misalignment of the apertures in abutting first stationary valve disk and first rotatable valve disk and alignment of the apertures in abutting second stationary valve disk and second rotatable valve disk.
- the second disk position is characterized by misalignment of the apertures in abutting alignment second stationary valve disk and second rotatable valve disk and alignment of the apertures in abutting first stationary valve disk and first rotatable valve disk.
- Rotation to the first disk position permits flow of fluid from the at least one inlet port, through inlet passage, the mixing chamber, the valve chamber, and the first rotatable and stationary valves to one of the pair of outlet passages
- rotation to the second disk position permits flow of fluid from the at least one inlet port, through the inlet passage, the mixing chamber, the valve chamber, and the second rotatable and stationary valves to the other of the pair of outlet passages.
- the rotatable valve disks are further rotatable about the axis of the cylindrical valve chamber to a third disk position characterized by misalignment of the apertures in abutting first stationary valve disk and first rotatable valve disk and misalignment of the apertures in abutting second stationary valve disk and second rotatable valve disk, whereby rotation to the third disk position blocks flow of fluid from the at least one inlet port to both of the pair of outlet passages.
- first and second stationary valve disks and a rotatable valve disk are mounted in the valve chamber.
- the rotatable valve disk is axially aligned with, abutting, and positioned between the stationary valve disks, and each valve disk includes at least one aperture therethrough.

- the housing, mixing chamber, outlets and inlets, and portions of the valve assembly 20 are all shown in phantom to clearly show their relationship to other portions of the valve assembly 20 according to the invention.
- Supply inlets 12 and 14 are typically a cold and a hot water supply, respectively, and combine in the mixing chamber 22 in the diverter valve 10 to provide the desired temperature water to the outlets 12 or 14.
- the outlet 18 typically supplies a showerhead (not shown) and the outlet 16 typically supplies a tub spout (not shown).
- the valve assembly 20 controls whether the water in the mixing chamber 22 is supplied to either the outlet 16 or 18 and the showerhead or the tub spout, respectively.
- the valve assembly 20 is normally threaded into the housing 26 of the diverter valve 10.
- the valve assembly 20 comprises a valve disks 60, 62. 64, 66 for controlling fluid flow, a housing 30 defining a valve chamber between the valve disks 60, 62, a stem 40 disposed coaxiallv within the housing 30 for selectively rotating the disks 60, 64 and a casing 50, a cap 100 on a distal end of the casing 50, and O-rings 110 providing seals between the related parts.
- the hollow housing 30 includes a partially threaded tubular housing wall 28 that partially encases the stem 40, casing 50 and disks 60, 62, 64, 66.
- the housing 30 includes an outlet passage 41, typically for supplying a tub spout, and an inlet passage 43, which receives supply fluid from the mixing chamber 22.
- the casing 50 includes an aperture 54, which receives supply fluid from the inlet passage 43, and communicates the supply fluid to the valve chamber.
- the housing 30 is roughly divided into a front portion 34 and a rear portion 36 separated by the first set of adjacent disks 60, 62.
- the front portion 34 substantially houses the stem 40 and includes an arcuate milled slot 32 therein and an outlet passage 41.
- the rear portion 36 substantially houses the casing 50 and the second set of adjacent disks 64, 66. Both the stem 40 and the casing 50 are rotatably mounted within their respective portions of the housing 30.
- the arcuate milled slot 32 is medially disposed circumferentially on the housing wall 28 of the housing 30 and receives a stop pin 42 therein.
- the stop pin 42 extends transversely from the stem 40 and travels in slot 32 in the housing wall 28.
- the slot 32 extends approximately 180 degrees of the peripheral circumference of the housing wall 22, as best shown in FIGS. 2, 4, 6, and includes ends 24 diametrically opposed on the slot 32. The ends 24 block the stop pin 42 from movement beyond the confines of the slot 32.
- the stem 40 can rotate only the approximately 180 degrees defined by the slot 32.
- the stem 40 includes a stop pin 142 near its proximal end and the housing 30 includes a ledge 144 diametrically extending from the housing generally parallel and coplanar to the axis of rotation of the stem 40.
- the stop pin 142 extends generally transversely from the stem 40 and is aligned with the ledge 144 such that it abuts it upon 180° rotation in either direction. In this manner, the ledge 144 forms a stop for the pin 142, whereby the limits of valve stem 40 rotation are defined. Of course, more or less than 180 degrees of rotation can be provided by changing the shape of the ledge 144.
- the first and second pairs of disks 60, 62 and 64,66 control water flow through the diverter valve 10 depending upon the relative position of adjacent disks. More specifically, the pair of adjacent disks 60, 62 control water flow to supply outlet 16 and the pair of disks 64, 66 control water flow to the supply outlet 18. In conjunction, the pairs of disks 60, 62 and 64, 66 can stop water flow to both supply outlets 16 and 18.
- the disks are preferably composed of ceramic material.
- the pairs of disks 60, 62 and 64, 66 include, respectively, rotating disks 60 and 64 as well as stationary disks 62 and 66.
- the disks 60, 64 engage and can rotate relative to the adjacent and coaxial disks 62, 66, respectively.
- Each disk 60, 62, 64, 66 has a face 92 and a circumferential edge 96, and rotating disks 60, 64 have a pair of grooves 80 diametrically opposed on the circumferential edge 96.
- each face 92 includes a pair of triangular apertures 90 diametrically opposed therethrough with pinnacles 94 approaching the center of the disk.
- disks 60, 62, 64, 66 are mounted flush such that each has a face 92 in frictional engagement with another, thereby providing a seal against the passage of fluid when the openings 90 are not aligned, and providing a passage for fluid when the openings 90 are aligned.
- the O-rings 110 are positioned adjacent the disks 62, 64, 66 to seal the disk assemblies against leaking fluid from around the circumferential edge 96 of each of the disks.
- the barrel-shaped casing 50 has a proximate end 52 with arcuate slots 82 diametrically-opposed on the periphery thereof and separated by arcuate tabs 84, as best shown in FIG. 8.
- the casing 50 mounts the disk 64 at a distal end 58 thereof and further includes apertures 54 communicating with the inlet passage 43 for supplying fluid to the valve chamber between valve disks 62, 64.
- the apertures 54 and inlet passage 43 accommodate fluid flow from the mixing chamber 22 to either outlet 16, 18 through pairs of disks 60, 62 and 64, 66, respectively.
- the disk 66 which is secured by the cap 100 is mounted flush and coaxial with the disk 64 and adjacent the distal end 58.
- the cap 100 covers a distal end 38 of the rear portion
- the cap 100 further includes an annular ring 104 that extends into the casing 50.
- the ring 104 has diametrically opposed slots 106 adapted to receive tabs 86 on the disk 66 and secure it against rotation.
- the cap 100 fixably mounts disk 66, which lies coaxial and adjacent to disk 64, which rotates with the casing 50.
- the stem 40 includes the transverse-extending pin 42, an operating end 44 and an actuating end 46.
- the operating end 44 extends from the front portion 34 of the housing 30 and is adapted to receive a handle 48, as shown in FIGS. 2, 4, 6, and 9, for use such that a user can selectively operate the tub or shower spout (not shown) by rotating the stem 40.
- the slot 32 in the housing 30 receives the pin 42 of the stem 40 to permit rotation within the limits of the slot 32.
- the actuating end 46 of the stem 40 includes inner flanges 70 and outer flanges 72 on a U-shaped extension 78, as best seen in FIG. 9.
- the inner flanges 70 are opposed tabs on an inner surface of the extension 78.
- the outer flanges 72 are the distal-most points on the extensions 78 of the actuating end 46.
- the inner flanges 70 on the actuating end 46 of the stem 40 are received in the adapted grooves 80 in the disk 60, whereby the disk 60 is forced to rotate when the stem 40 is rotated at its operating end 44.
- the outer flanges 72 travel in the arcuate slots 82 located on the periphery of the end 52 of a casing 50 and engage the arcuate tabs 84 upon sufficient rotation of the stem 40. whereupon the casing 50 is rotated.
- the disk 64 is mounted at the distal end 58 of the casing 50, whereby rotation of the casing 50 by force of the outer flange 72 against the arcuate tab 84 causes disk 64 to rotate against adjacent, fixed disk 66.
- the relative position of the pairs of disks 60, 62 and 64, 66 controls the flow of water through the diverter valve 10.
- the apertures 90 in the disks 60, 62 are aligned water can flow through the diverter valve to the outlet 16.
- the apertures 90 in the disks 64, 66 are aligned water can flow through the diverter valve
- the inner flange 70 of the actuating end 46 of the stem 40 rotates the disk 60.
- the disk 64 is rotated by the end 52 of the casing 50 which, in turn, is rotated by the outer flange 72 of the actuating end 46 of the stem 40.
- the relative position of the disks 60, 62 and 64, 66 is controlled by rotation of the stem 40 in both a clockwise and counterclockwise direction.
- valve assembly 20 Operation of the valve assembly 20 is defined by three relative disk positions as illustrated by FIGS. 2 and 3, 4 and 5, 6 and 7, respectively. Each will be described specifically, and rotations of the valve stem are from the perspective of a user operating the handle 48.
- FIG. 3 illustrates the position of the outer flanges 72 in the arcuate slots 82 of the casing 50 when the disks are in this position.
- the stem 40 and the casing 50 are rotated fully clockwise by the user (in the direction of the arrow A in the rear view of FIG. 4), such that the stop pin 42 is rotated to the bottom of the milled slot 32 in the housing 30 and the inner flange 70 on the extension 78 of the actuating end 46 urges the disk 60 to rotate against the disk 62. Further, the outer flange 72 traveled freely in the arcuate slots 82 from one tab 84 to the other tab 84 so that the casing 50 does not rotate. In this position, the apertures 90 in the disks 60.
- the apertures 90 in the disks 64, 66 are not aligned, thereby preventing flow therethrough, because rotation clockwise by the user from the first position, as shown in FIG. 2, does not rotate the casing 50 which would cause the disk 64 to rotate. Rather, the outer flange 72 rests against the arcuate tab 84 as shown in FIG. 5.
- the stem When the user rotates the stem counterclockwise approximately 90 degrees the stem is rotated back to the first, or stop valve, position as illustrated in FIG. 2. That is, the first disk 60 rotates such that the apertures in the disks 60 and 62 are not aligned, thereby closing the path to the tub spout through supply outlet 16.
- the outer flange 72 on the extension 78 travels the length of the slot 82 between the arcuate tabs 84, but not far enough to cause the casing 50 to move also. Because this rotation of the stem 40 does not rotate the casing 50, it cannot align the apertures 90 in the disks 64, 66, which would allow water to flow to the supply outlet 18 and the showerhead.
- the third position is defined by full rotation of the stem 40 in a counterclockwise direction (in the direction of the arrow C in the rear view of FIG. 6) such that the stop pin 42 is rotated to the end 24 of the milled slot 32 in the housing 30.
- the outer flange 72 on the extension 78 on the stem 40 strikes the abutting arcuate tab 84 on the casing 50 on the periphery of the end 52, as shown in FIG. 5, thereby urging the casing 50 to rotate also, which automatically forces the disk 64 to rotate against the disk 66 such that the apertures 90 therethrough become aligned.
- FIG. 7 depicts the relation of the outer flange 72 and the arcuate tab 84 in this third position.
- the valve assembly can be returned to the first, or stop valve, position by rotating the stem approximately 90 degrees counterclockwise, whereupon the apertures 90 in both pairs of disks 60, 62 and 64, 66 are out of alignment and flow through the diverter valve 10 is stopped, as best shown in FIG. 2.
- the alternative valve assembly 220 includes a housing 230, a stem 240, a casing 250, and disks 260, 262, and 264.
- the hollow housing 230 has a partially threaded tubular housing wall 228 that partially encases the stem 240, casing 250, and disks 260, 262, 264.
- the disks 260, 262, 264 are preferably composed of ceramic material.
- the housing 230 is approximately divided into a larger diameter front portion
- the more forward opening is an outlet 239 supply, which typically connects to a tub spout (not shown), and the more rearwardly disposed opening is an inlet 241, which receives fluid, typically water, supplied by a connected source (not shown).
- An annular ring 243 separates the front portion 234 and rear portion 236 and further functions as a mounting stop including a sealing ring 247 on its rearwardly facing surface for providing a sealed mounting upon proper installation of the housing 230.
- the foremost end of the front portion 234 includes a hexed end 245 adapted to be received by a tool, such as a wrench, for installing the housing 230. Further, a bore 231 extending from the front portion 234 to the rear portion 236 defines the hollow housing 230. In the front portion 234 a bore 231 is a smaller diameter than in the rear portion 236.
- the valve stem 240 includes an operating end 244 and an actuating end 246.
- the operating end 244 which extends from within the bore 231 through the hexed end 245 of the housing 230, is adapted to receive a handle (not shown), whereby a user can selectively operate the tub or shower spout by rotating the stem 240.
- the stem 240 is limited to approximately 90° of rotation by diametrically opposed flanges 222 formed to extend from the valve stem 240 transverse to its axis of rotation and diametrically opposed arcuate grooves 224 formed on an internal wall 226 of valve housing 230.
- the arcuate grooves 224 each are formed from approximately 90° of a portion of the internal wall 226 and define ends 225 that block rotation of the flanges 222 beyond the 90° defined by the arcuate grooves 224, as illustrated in phantom in FIG. 12.
- the valve stop mechanisms described above for the prior embodiments of the invention could alternatively be used with this embodiment of the invention; further, this valve stop mechansim can be used with the prior embodiments of the invention.
- O-rings 227, 237 provide seals between respective portions of the valve stem 240 and an internal surface of the valve housing 230.
- the actuating end 246 of the stem 240 includes opposed flanges 270 formed parallel to the axis of rotation of the stem 240.
- the opposed flanges 270 each include aligned aperture 272 therethrough for receiving a pin 271 for connecting the valve stem 240 to the disk 262, which connection allows the central disk 262 to rotate with the valve stem 240 as will be explained more fully below.
- the barrel-shaped casing 250 has an open end 252 with slots 282 formed diametrically opposed on the periphery thereof, as well as a substantially closed distal end 258 with an outlet 259 to the tub formed therein.
- the open end 252 receives the assembly of disks 260, 262, 264, O-rings 253, and the actuating end 246 of the valve stem 240.
- An O-ring 251 forms a seal between the valve stem 240 and the casing 250.
- the body of the casing 250 includes large opposed openings 285 for providing fluid flow to either the tub or shower as determined by the relative positions of the disks 260, 264.
- the distal end 258 further includes slots 284 (only one is shown in FIG. 11) formed diametrically opposed on an inner periphery of the casing 250.
- the slots 282, 284 are adapted to retain disks 260. 264, respectively, which are mounted stationary relative the central disk 262, which rotates with the valve stem 240. Further, the slots 282 are offset 90° relative the slots 284, whereby the disk 264 is offset 90° relative the disk 260, as will be explained further below.
- Each end 252, 258 also mounts an O-ring 253 adjacent the disks 260, 264, respectively, for providing a seal between the disks 260, 264 and the tubular housing of the casing 250.
- Each disk 260, 262, 264 has a face 292 and a circumferential edge 296, and stationary disks 260, 262 include a pair of diametrically opposed tabs 286 on their circumferential edges 296. Further, each face 292 of disks 260, 264 includes the pair of triangular openings 290 defining diametrically opposed fluid flow paths therethrough with pinnacles 294 approaching the center of the disk.
- the disks 260, 264 are identical and are mounted in slots 282, 284 offset 90° relative one another, the openings 290 therethrough are offset 90° relative one another, as illustrated in FIGS. 12-14.
- the central disk 262, which rotates with the valve stem 240, is generally bow tie shaped.
- the central disk 262 includes opposed generally triangular openings 291 formed at the periphery thereof for defining a fluid flow path and openings 297 formed diametrically opposed on the circumferential edge 296 for receiving the pin 271 through the opening 272 in the flange 270 for connecting the valve stem 240 to the disk 262, which connection allows the central disk 262 to rotate with the valve stem 240.
- the disks 260, 264 are aligned and mounted flush relative the central disk 262 such that each disk 260, 264 has a face 292 in frictional engagement with a face 292 of the central disk 262 to provide a seal against the passage of fluid when either opening 290 is not aligned with opening 291, and providing a passage for fluid when either opening 290 is aligned with opening 291.
- FIGS 13-15 illustrate the relative positions of the disks 260, 262, 264 in order to control fluid flow through the valve assembly 220.
- the opening 290 in disk 260 is labeled as flow passage "A”
- the opening 291 in disk 262 is labeled as flow passage "B”
- the opening 290 in disk 264 is labeled as flow passage "C”.
- Aligned flow passages permit fluid to flow to either the tub or shower spout, while misaligned flow passages stop or decrease fluid passage to either the tub or shower spout. All views are taken from just forward of disk 260; thus flow passage A is foremost in the figures, while flow passages B and C are shown in phantom except when aligned with flow passage A.
- valve stem 240 In a first position, with reference to FIG. 13. the valve stem 240 is rotated, whereby central disk 262 is rotated, until openings 291 are aligned with openings 290 in disk 264. Because the disks 260, 264 are offset 90° relative one another, flow passage A is aligned with face 292 of central disk 262 and flow passages B and C are aligned for fluid communication, as shown in phantom. Fluid flows from a source, through the inlet 241 in the valve housing 230. through the openings 285 in the casing 250, through the flow passage B, through the flow passage C, through the outlet 259 in the distal end 258 of casing 250, and to the shower spout (not shown).
- Rotating the valve stem 240 approximately 90° causes the central disk 262 to rotate 90°, whereby openings 291 in central disk 262 are aligned with openings 290 in disk 260.
- This position is illustrated in FIG. 14, in which flow passage A is aligned with flow passage B for fluid communication, and flow passage C (shown in phantom) is aligned with face 292 of central disk 262 to block fluid flow in that direction.
- fluid flows from a source, through the inlet 241 in the valve housing 230, through the openings 285 in the casing 250, through the flow passage B, through the flow passage A, through the outlet 239 in the rear portion 236 of the valve housing 230, and to the tub spout (not shown).
- FIG. 15 An example of an intermediary position is illustrated in FIG. 15, in which fluid passages A and B are at least partially aligned and fluid passages B and C are at least partially aligned.
- the degree of flow to either flow passage A or flow passage C, and thus to the tub spout or to the shower spout is determined by the area of overlap of flow passage B and flow passage A relatively the area of overlap of flow passage B and flow passage C, which areas of overlap are inversely related.
- the central disk 262 includes slots 297 formed diametrically opposed on the circumferential edge 296 for receiving the pin 271 for connecting the valve stem 240 to the disk 262, which connection allows the central disk 262 to rotate with the valve stem 240.
- a central disk 362 includes tabs 397 formed diametrically opposed on the circumferential edge 396 for reception by slots 399 formed in the actuating end 346 of the valve stem 340 for connecting the valve stem 340 to the disk 362, which connection allows the central disk 362 to rotate with the valve stem 340 and relative stationary disks 360, 364.
- this variation operates and is constructed in the same manner as the other embodiments.
