DIVERTER VALVE WITH HANDLE

Abstract

A diverter valve assembly which eliminates rotational motion for actuation.

Description

BACKGROUND

The present invention relates to a diverter valve, and more particularly to a diverter valve for a shower and tub.

Diverter valves are often utilized to control water flow from a bathtub faucet or a shower head. Current diverter valves utilize a rotational cam device to divert the water flow. This may be undesirable as the rotational motion may wear seals within the diverter valve.

SUMMARY

A diverter valve assembly according to an exemplary aspect of the present invention includes: a valve body which defines an inlet, a first outlet and a second outlet; a rigid core; a resilient core mounted to the rigid core; and a handle core engaged with the rigid core, the handle core movable between a first position and a second position, the first position engages the resilient core with the valve body and blocks the second outlet to divert a fluid from the inlet to the first outlet, the second position engages the resilient core with the valve body and block the first outlet to divert the fluid from the inlet to the second outlet.

The diverter valve assembly eliminates the need for rotational motion to divert water by a push method which reduces seal wear. The diverter valve assembly is also relatively easier to operate as no rotation is required.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

FIG. 1A schematically illustrates a diverter valve assembly 20. The diverter valve assembly 20 generally includes an inlet 22 a first outlet 24, a second outlet 26 and a handle 28. The handle 28 is movable between a first position A to divert water from the inlet 22 to the first outlet 24 and a second position B to divert water from the inlet 22 to the second outlet 26 (FIG. 1B). The diverter valve assembly 20 eliminates the need for rotational motion which reduces seal wear. The diverter valve assembly 20 is also relatively easier to operate by this no rotation required switch method.

Referring to FIG. 2, an exploded view of the diverter valve assembly 20 is illustrated. The diverter valve assembly 20 generally includes the handle 28, a housing front cover 30, a flange 32, a handle core 34, a fix plate 36, a rigid core 38, a resilient core 40, a detent 42, a spring 44, a valve body 46, a housing 48 and a housing back cover 50. The resilient core 40 is mounted within the rigid core 38 to define an effective seal surface within the valve body 46. The resilient core 40 may be manufactured of a resilient material such as rubber or other seal material while the rigid core 38 is manufactured of a relatively more rigid material such as a plastic or the like of which the over diverter valve assembly 20 components are manufactured.

The rigid core 38 with the resilient core 40 retained therein is movably retained within the valve body 46 by the fix plate 36. The fix plate 36 may be snapped with an interference fit, threaded or otherwise attached to the valve body 46. The handle core 34 is captured within the fix plate 36 by the flange 32. The flange 32 is snapped with an interference fit, threaded or otherwise attached to the fix plate 36. The flange 32, handle core 34 fix plate 36, rigid core 38/resilient core 40 as assembled to the valve body 46 provides a subassembly to be mounted within the housing 48 and enclosed therein by the housing front cover 30 and back cover 50.

The handle 28 is thereby pivotally retained within the housing front cover 30 to actuate the handle core 34. The handle 28 is mounted to the handle core 34 such that movement of the handle 28 pivots the handle core 34. The handle core 34 pivots relative the fix plate 36 about a ball section 34B which defines a pivot T of the handle core 34. The handle core 34 pivots about pivot T to slide the rigid core 38 within the valve body 46. The handle 28 and thus the handle core 38 is movable between a first position (FIGS. 3A-3C) and a second position (FIGS. 4A-4C) with an intermediate position (FIGS. 5A-5C) therebetween.

The rigid core 38 includes a detent pocket 52 which receives the detent 42 which is biased by the spring 44. The detent 42 is engageable with a series of recesses 54A, 54B, 54C (best seen in FIGS. 3B, 4B, and 5B) to further define the positions A, B and C. The rigid core 38 further includes a tab 56 which is engageable with a slot 58 defined within the valve body 46 (best seen in FIGS. 3C, 4C, and 5C). The detent 42 engagement with the series of recesses 54A, 54B, 54C and the tab 56 engagement with the slot 58 facilitate movement control of the rigid core 38 within the valve body 46.

Referring to FIG. 3A, the first position A engages the resilient core 40 with the valve body 46 and blocks the second outlet 26 to divert a fluid from the inlet 22 to the first outlet 24. The rigid core 38 slides within the valve body 46 such that the resilient core 40 essentially plugs a second valve body opening 46B (FIG. 3B). The fluid flows from the inlet 22 to pass between a wall 46W of the valve body 46 and the fix plate 36 (FIG. 3C).

Referring to FIG. 4A, the second position B engages the resilient core 40 with the valve body 46 and block the first outlet 24 to divert fluid from the inlet 22 to the second outlet 26. The rigid core 38 slides within the valve body 46 such that the resilient core 40 essentially plugs a first valve body opening 46A (FIGS. 4B and 4C).

Referring to FIG. 5A, an intermediate position C of the handle 28 and thus the handle core 38 permits fluid to flow the inlet 22 to both the first outlet 24 and the second outlet 26 (FIGS. 5B). The rigid core 38 is located within the valve body 46 such that the resilient core 40 plugs neither the first valve body opening 46A or the second valve body opening 46B (FIG. 5C).
