Abstract

This diverter valve (12) is used in conjunction with a faucet (14) and provides for partial diversion of the water supply to a chemical block feeder (20). The diverter valve includes a body 24 having an inlet (26) an outlet 28 and a connecting intermediate passage (32). A transverse diverter passage (42) on one side of the body 24 communicates with the intermediate passage (32) and the diverter passage is closed by an aligned plunger (50) mounted to the opposite side of the body (24). The plunger (50) is withdrawn from its closure position by pulling outwardly and is maintained in the open position by water pressure to partially divert water into the diverter passage (42) to supply diluted chemical into a sink (16).

Claims

1. A diverter valve, comprising:

(a) body including first passage means extending therethrough, said passage means having an inlet opening at one end, and an outlet opening at the other end, said second transversely disposed, diverter passage means communicating with said first passage means between said ends at one side of the body, said second passage means having a valve seat, and

(b) diverter member slidingly mounted to the other side of said body and including an inner end portion disposed inside the body, an outer end portion disposed outside the body and an intermediate portion connecting said inner and outer end portions, said inner end portion being movable between a closed position engageable with said valve seat and an open position spaced from said valve seat,

(c) said diverter member extending across the first passage means in the closed position and being adapted to permit flow through the first passage means when the diverter passage means is open and when the diverter passage means is closed so that there is always flow through the first passage means both when the diverter member is in the closed position and when the diverter member is in the open position, and

(d) the diverter member including means spring-biasing said member into the closed position.

2. diverter valve as defined in claim 1 in which:

(e) said valve seat is recessed, and

(f) the diverter member is a plunger having a knob providing said outer end portion, a valve disc providing said inner end portion and being received within said recessed valve seat, and a reduced diameter rod providing said intermediate portion and extending between said knob and said disc, to minimize obstruction of flow through said first passage means when said diverter member is in the closed position.

3. A diverter valve, comprising:

(a) a body including first passage means extending therethrough, said passage means having an inlet opening at one end, and an outlet opening at the other end, and second, transversely disposed, diverter passage means communicating with said first passage means between said ends at one side of the body, said second passage means having a valve seat, and

(b) a diverter member mounted to the other side of said body and including an inner end portion disposed inside the body, an outer end portion disposed outside the body and an intermediate portion connecting said inner and outer end portions, said inner end portion being movable between a closed position engageable with said valve seat and an open position spaced from said valve seat,

(c) said diverter member extending across the first passage means in the closed position and being adapted to permit flow through the first passage means when the diverter passage means is open and when the diverter passage means is closed so that there is always flow through the first passage means both when the diverter member is in the closed position and when the diverter member is in the open position, and

(d) the inlet opening and the outlet opening being substantially axially aligned and the first passage means including an intermediate portion offset from the axis of alignment.

4. A diverter valve as defined in claim 3, in which:

(e) the first passage means includes an auxiliary passage portion disposed in side-by-side relation with said intermediate passage portion and operatively communicating between said intermediate passage portion and said outlet opening and providing part of said first passage means when the diverter member is in the closed position.

5. A diverter valve, comprising:

(a) a body including first passage means extending therethrough, said passage means having an inlet opening at one end, and an outlet opening at the other end, and second, transversely disposed, diverter passage means communicating with said first passage means between said ends at one side of the body, said second passage means having a valve seat, and

(b) a diverter member mounted to the other side of said body and including an inner end portion disposed inside body and including an inner end portion disposed inside the body, an outer end portion disposed outside the body and an intermediate portion connecting said inner and outer end portions, said inner end portion being movable between a closed position engageable with said valve seat and an open position spaced from said valve seat,

(c) said diverter member extending across the first passage means in the closed position and being adapted to permit flow through the first passage means when the diverter passage means is open and when the diverter passage means is closed so that there is always flow through the first passage means both when the diverter member is in the closed position and when the diverter member is in the open position, and

(d) the valve body including a transverse mounting passage substantially axially aligned with said second diverter passage means and including a spring housing having an abutment,

(e) said diverter member being a plunger having a knob providing said outer end portion, a valve disc providing said inner end portion and a reduced diameter rod extending between said know and said disc, and

(f) a biasing spring being disposed in said chamber between said disc and said abutment.

6. A diverter valve as defined in claim 5, in which:

(g) the inlet opening and the outlet opening are substantially axially aligned and the first passage means includes an intermediate passage portion offset from the alignment axis, and an auxiliary passage portion extending between said said mounting passage and said outlet opening and operatively communicating with said intermediate passage portion when the plunger is in the closed position.

7. A diverter valve as defined in claim 6, in which:

(h) said intermediate passage portion and said auxilliary passage portion are disposed in side-by-side relation and said auxiliary passage communicates with said spring chamber.

8. A diverter valve, comprising:

(a) a body including first passage means extending therethrough, said passage means having an inlet opening at one end, and an outlet opening at the other end, and second, transversely disposed, diverter passage means communicating with said first passage means between said ends at one side of the body, said second passage means having a valve seat, and

(b) a diverter member slidingly mounted to the other side of said body and including an inner end portion disposed inside the body, an outer end portion disposed outside the body and an intermediate portion connecting said inner and outer end portions, said inner end portion being movable between a closed position engageable with said valve seat and an open position spaced from said valve seat,

(c) said diverter member extending across the first passage means in the closed position and being adapted to permit flow through the first passage means when the diverter passage means is open and when the diverter passage means is closed sot that there is always flow through the first passage means both when the diverter member is in the closed position and when the diverter member is in the open position; and

(d) said valve seat being recessed, and

(e) the diverter member being a plunger having a knob providing said outer end portion disposed outside of the body, a valve disc providing said inner end portion and being received within said recessed valve seat, and a reduced diameter rod providing said intermediate portion and extending between said knob and said disc, to minimize obstruction of flow through said first passage means when said diverter member is in the closed position, and

(f) the plunger being mounted in a mounting passage, said passage having a recessed portion receiving said valve disc when said plunger is in said open position.

(g) the diverter member including means spring biasing said member into the closed position.
