Hand-held dispenser and related methods
A hand-held beverage dispenser includes a handle body, within which multiple valve units are contained. Two sets of fluid flow paths are provided into the handle body. The sets of fluid flow paths are mutually exclusive one to the other. Each flow path of the first set is in fluid communication with each valve unit, whereas only a predetermined one of the second set of fluid flow paths is in fluid communication with each valve unit. Each valve unit includes a flow control valve and a selection valve. The selection valve determines on an ad hoc basis which of the first set of flow paths will be utilized at any given time, while the flow control valve provides single action simultaneous ON-OFF control of fluid flows through both the selected flow path and the predetermined flow path.
1. A valve arrangement for selectively establishing beverage fluid flow paths through a hand-held beverage dispenser, said valve arrangement comprising:
a selector valve substantially contained within a hand-held beverage dispenser;
a plurality of flow paths from without said hand-held beverage dispenser to said selector valve, wherein said selector valve is adapted to:
establish passage through said selector valve of a user selectable one of said plurality of flow paths; and
block passage through said selector valve of each said plurality of flow paths other than said one of said plurality of flow paths; and
a flow control valve substantially contained within said hand-held beverage dispenser, wherein:
said flow control valve and said selector valve are functionally independent; and
said flow control valve is adapted, upon actuation, to enable fluid discharge from said one of said plurality of flow paths to without said hand-held beverage dispenser.
2. The valve arrangement as recited in claim 1 , wherein said flow control valve and said selector valve are formed about a single valve body.
3. The valve arrangement as recited in claim 2 , wherein said flow control valve is integrally formed with said selector valve.
4. A valve arrangement for selectively establishing beverage fluid flow paths through a hand-held beverage dispenser, said valve arrangement comprising:
a plurality of selector valves substantially contained within a hand-held beverage dispenser;
a first plurality of flow paths, each flow path of said first plurality of flow paths being from without said hand-held beverage dispenser to each said selector valve, wherein each said selector valve is adapted to:
establish passage through said selector valve of a user selectable one of said first plurality of flow paths; and
block passage through said selector valve of each said first plurality of flow paths other than said one of said first plurality of flow paths; and
for each said selector valve, a corresponding flow control valve substantially contained within said hand-held beverage dispenser, wherein:
each said flow control valve and corresponding said selector valve are functionally independent; and
each said flow control valve is adapted, upon actuation, to enable fluid discharge from said one of said first plurality of flow paths to without said hand-held beverage dispenser.
5. The valve arrangement as recited in claim 4 , wherein each said flow control valve and corresponding said selector valve are formed about a single valve body.
6. The valve arrangement as recited in claim 5 , wherein each said flow control valve is integrally formed with its corresponding said selector valve.
7. The valve arrangement as recited in claim 4 , said valve arrangement further comprising a second plurality of flow paths, and wherein:
said second plurality of flow paths and said first plurality of flow paths are mutually exclusive;
for each said flow control valve, a predetermined corresponding one of said second plurality of flow paths is from without said hand-held beverage dispenser to said flow control valve; and
each said flow control valve is further adapted, upon actuation, to enable fluid discharge from said corresponding one of said second plurality of flow paths to without said hand-held beverage dispenser.
8. The valve arrangement as recited in claim 7 , wherein each said selector valve is rotationally operated.
9. The valve arrangement as recited in claim 8 , wherein each said selector valve comprises a gate valve.
10. The valve arrangement as recited in claim 8 , said valve arrangement further comprising a locking mechanism adapted to maintain each said selector valve in a respective operable state.
11. The valve arrangement as recited in claim 8 , wherein:
each said selector valve comprises a rotatable tab;
said hand-held beverage dispenser comprises a set of tab stops;
said tab stops are cooperatively adapted with said rotatable tab to limit operative rotation of said selector valve to an arc between a first operable state and a second operable state.
12. The valve arrangement as recited in claim 11 , wherein:
each said selector valve comprises a gate valve; and
said rotatable tab rotates with a gate of said gate valve.
13. The valve arrangement as recited in claim 12 , wherein each said tab stop of a selector valve is integrally formed with a valve body of said selector valve.
14. The valve arrangement as recited in claim 11 , said valve arrangement further comprising a locking mechanism adapted to maintain each said selector valve in a respective operable state.
15. The valve arrangement as recited in claim 14 , wherein said locking mechanism comprises a plurality of locking tabs, each said locking tab being adapted to constrain rotation of a corresponding one of said selector valves.
16. The valve arrangement as recited in claim 15 , wherein each said locking tab is affixed to a selectively removable panel of said hand-held beverage dispenser.
17. The valve arrangement as recited in claim 16 , wherein said selectively removable panel comprises an exterior cover of said hand-held beverage dispenser.
18. The valve arrangement as recited in claim 16 , wherein said locking tabs are cooperatively adapted with said rotatable tabs and said tab stops to prevent attachment of said removable panel unless each said selector valve is in an operable state.
19. A method for selecting one of a plurality of diluent fluids for dispensing together with one of a plurality of beverage fluids from a hand-held beverage dispenser while the hand-held beverage dispenser is operably under pressure, said method for selecting one of a plurality of diluents comprising the steps of:
placing each of a plurality of pressurized diluent fluids in fluid communication with each of a plurality of selector valves, each said selector valve being substantially within a hand-held beverage dispenser;
for each said selector valve, placing one of a plurality of pressurized beverage fluids in fluid communication with a flow control valve corresponding to said selector valve, wherein each said flow control valve is:
substantially within said hand-held beverage dispenser;
functionally independent of its corresponding selector valve; and
adapted to selectively discharge a corresponding pressurized beverage fluid together with a corresponding selected one of said plurality of pressurized diluent fluids from said hand-held beverage dispenser; and
operating one of said plurality of selector valves to place a selected one of said plurality of pressurized diluent fluids in fluid communication with a corresponding flow control valve for dispensing said selected one of said plurality of pressurized diluent fluids together with a corresponding pressurized beverage fluid.
20. The valve arrangement as recited in claim 19 , wherein each said flow control valve and corresponding said selector valve are formed about a single valve body.
21. The valve arrangement as recited in claim 20 , wherein each said flow control valve is integrally formed with its corresponding said selector valve.
