Abstract

A beverage dispensing valve includes a manifold that receives and dispense a first liquid and a second liquid. The manifold has a first flow channel through which the first liquid is conveyed and a second flow channel through which the second liquid is conveyed. A first shutoff assembly has a valve seal on a leg disposed in the first flow channel and a second shutoff assembly has a valve seal on a leg disposed in the second flow channel. A handle assembly is coupled to the first shutoff assembly and the second shutoff assembly and movement of the handle assembly simultaneously moves the leg of the first shutoff assembly and the leg of the second shutoff assembly into an open position such that the first liquid flows through the first flow channel, the second liquid flows through the second flow channel, and the first liquid and second liquid mix downstream to form a mixed beverage.

First claim

What is claimed is:

1. A beverage dispensing valve comprising:
a manifold configured to receive and dispense a first liquid and a second liquid, the manifold has a first flow channel through which the first liquid is conveyed and a second flow channel through which the second liquid is conveyed, the second flow channel being parallel to and separated from the first flow channel;
a first shutoff assembly has a valve seal on a leg disposed in the first flow channel, the leg is movable into and between a closed position in which the valve seal blocks the flow of the first liquid through the first flow channel and an open position in which the valve seal is in an open position such that the first liquid flows through the first flow channel;
a second shutoff assembly has a valve seal on a leg disposed in the second flow channel, the leg is movable into and between a closed position in which the valve seal blocks the flow of the second liquid through the second flow channel and an open position in which the valve seal is in an open position such that the second liquid flows through the second flow channel;
a handle assembly coupled to the first shutoff assembly and the second shutoff assembly such that movement of the handle assembly moves the leg of the first shutoff assembly and the leg of the second shutoff assembly into the open position such that the first liquid flows through the first flow channel, the second liquid flows through the second flow channel, and the first liquid and the second liquid mix downstream of the first flow channel and the second flow channel to form a mixed beverage;
a nozzle into which the first liquid is dispensed from the first flow channel and the second liquid is dispensed from the second flow channel, wherein the nozzle mixes the first liquid and the second liquid to form the mixed beverage, and wherein the first liquid remains separated from the second liquid until the first liquid and the second liquid are mixed in the nozzle;
wherein the nozzle has an inner perimeter surface, a chamber, and a diffuser positioned in the chamber;
wherein the diffuser directs the first liquid toward the inner perimeter surface such that the first liquid is conveyed by gravity along the inner perimeter surface;
wherein the diffuser is configured to spray the second liquid toward the inner perimeter surface such that the second liquid mixes with the first liquid to form the mixed beverage;
wherein the first shutoff assembly has an arm pivotally coupled to and extending transverse to the leg of the first shutoff assembly;
wherein the second shutoff assembly has an arm pivotally coupled to and extending transverse to the leg of the second shutoff assembly; and
wherein the handle assembly couples to the arm of the first shutoff assembly and the arm of the second shutoff assembly.

2. The beverage dispensing valve according to claim 1 , wherein the leg of the first shutoff assembly has a flange that contacts the valve seal as the leg is moved toward the open position; and
wherein the leg of the second shutoff assembly has a flange that contacts the valve seal when the leg is moved toward the open position.

3. The beverage dispensing valve according to claim 1 , further comprising:
a flow control body configured to receive the first liquid from a first liquid source and the second liquid from a second liquid source and dispense the first liquid to the first flow channel and the second liquid to the second flow channel, the flow control body has a first flow control that controls flow rate of the first liquid and a second flow control that controls flow rate of the second liquid; and
at least one connector ring that couples the flow control body to the manifold.

4. The beverage dispensing valve according to claim 3 , wherein the flow control body has a first pressure reducing insert that gradually reduces pressure of the first liquid as the valve seal of the first shutoff assembly is opened and a second pressure reducing insert that gradually reduces pressure of the second liquid as the valve seal of the second shutoff assembly is opened to thereby prevent gases in the first liquid or the second liquid from coming out of solution.

5. The beverage dispensing valve according to claim 1 , wherein the diffuser extends along an axis and has a first perforated ring, a radially outwardly sloping deflector surface downstream from the first perforated ring, and a second perforated ring downstream of the radially outwardly sloping deflector surface that collectively diffuse and radially outwardly direct the first liquid toward the inner perimeter surface.

6. The beverage dispensing valve according to claim 1 , wherein the diffuser has a center bore;
wherein the first flow channel has a first section and a second section that is transverse to the first section, the second section directs the first liquid into the chamber of the nozzle;
wherein the second flow channel has a first section and a second section that is transverse to the first section, the second section directs the second liquid to the center bore of the diffuser; and
wherein the first section of the first flow channel is parallel to the first section of the second flow channel.

7. A beverage dispensing valve comprising:
a manifold configured to receive and dispense a first liquid and a second liquid, the manifold has a first flow channel through which the first liquid is conveyed and a second flow channel through which the second liquid is conveyed;
a first shutoff assembly has a valve seal on a leg disposed in the first flow channel, the leg is movable into and between a closed position in which the valve seal blocks the flow of the first liquid through the first flow channel and an open position in which the valve seal is in an open position such that the first liquid flows through the first flow channel;
a second shutoff assembly has a valve seal on a leg disposed in the second flow channel, the leg is movable into and between a closed position in which the valve seal blocks the flow of the second liquid through the second flow channel and an open position in which the valve seal is in an open position such that the second liquid flows through the second flow channel;
a handle assembly coupled to the first shutoff assembly and the second shutoff assembly;
a dispensing arm coupled to the first shutoff assembly and the second shutoff assembly;
wherein movement of one of the handle assembly and the dispensing arm moves the leg of the first shutoff assembly and the leg of the second shutoff assembly into the open position such that the first liquid and the second liquid flow through the first and second flow channels and the first and second liquids mix downstream to form a mixed beverage; and
wherein movement of the handle assembly in a first direction moves the leg of the first shutoff assembly and the leg of the second shutoff assembly in a second direction opposite the first direction and pivots the dispensing arm from a rest position toward an open position.

8. The beverage dispensing valve according to claim 7 , wherein the dispensing arm has a first end and an opposite second end, and wherein the first end generally moves in the second direction as the dispensing arm pivots toward the open position.

9. The beverage dispensing valve according to claim 7 , wherein movement of the dispensing arm toward the open position moves the leg of the first shutoff assembly and the leg of the second shutoff assembly in the second direction and the moves the handle assembly in the first direction.

10. The beverage dispensing valve according to claim 8 , further comprising a flow control body configured to receive the first liquid from a first liquid
