Abstract

A tap for dispensing a beverage has a housing defining a channel for dispensing and a dispensing valve arranged in the housing. The valve is operable by a handle and connected via a tap drive shaft and a gear transmission to a valve drive shaft. The gear transmission has at least two cooperating gear wheels. The gear transmission could have a variable gear ratio. A method for manufacturing a tap for dispensing a beverage is disclosed.

First claim

The invention claimed is:

1. A tap for dispensing a beverage, comprising:
(a) a housing defining a dispensing channel for dispensing a beverage,
(b) a valve arranged in the housing allowing opening and closing the dispensing channel, said valve operable by a handle and connected to a valve drive shaft and said handle connected or to be connected to a tap drive shaft, and
(c) a gear transmission,

wherein the gear transmission comprises at least two cooperating gear wheels, a first gear wheel coupled to the tap drive shaft and a second gear wheel coupled to the valve drive shaft, at least one of said gear wheels being removable from the respective tap drive shaft or valve drive shaft.

2. The tap according to claim 1 , wherein the valve drive shaft extends in a longitudinal direction offset from the valve ending in an end portion and wherein the first gear wheel is coupled to said end portion of the valve drive shaft.

3. The tap according to claim 1 , wherein the tap drive shaft extends in a same longitudinal direction of the valve drive shaft ending in an end portion and wherein the second gear wheel is coupled to said end portion of the tap drive shaft.

4. The tap according to claim 1 , wherein the gear transmission comprises a planetary gear system having a sun gear, one or more planet gears and an annular gear, and wherein at least two of said sun gear, one or more planet gears and annular gear are respectively coupled to the valve drive shaft and the tap drive shaft and at least one mounted removably from the respective valve drive shaft or tap drive shaft.

5. The tap according to claim 1 , wherein the dispensing channel enables accommodating a disposable beverage line therein to be opened and closed by the valve.

6. A kit of parts comprising:
(a) a housing defining a dispensing channel for dispensing a beverage,
(b) a valve arranged in the housing allowing opening and closing the dispensing channel, said valve operable by a handle and connected to a valve drive shaft and said handle connected or to be connected to a tap drive shaft, and
(c) a gear transmission comprising at least two cooperating gear wheels, a first gear wheel to be removably coupled to the tap drive shaft and a second gear wheel to be removably coupled to the valve drive shaft.

7. The kit of parts according to claim 6 , wherein the tap drive shaft extends in a longitudinal direction offset from the valve ending in an end portion and wherein the first gear wheel is coupled to said end portion of the valve drive shaft, and wherein the tap drive shaft extends in the longitudinal direction of the valve drive shaft ending in an end portion and wherein the second gear wheel is coupled to said end portion of the tap drive shaft.

8. A method for manufacturing a tap for dispensing a beverage allowing control between a tap handle rotation and a valve actuation rate, said tap comprising: (a) a housing defining a dispensing channel for dispensing a beverage, (b) a valve arranged in the housing allowing opening and closing a dispensing channel, said valve operable by a handle and connected to a valve drive shaft and said handle connected to a tap drive shaft, and (c) a gear transmission comprising at least two cooperating gear wheels, a first gear wheel to be removably coupled to the tap drive shaft and a second gear wheel to be removably coupled to the valve drive shaft; the method comprising the steps of
assembling the housing, with the valve coupled to the valve drive shaft arranged therein;
mounting the tap handle on the tap drive shaft;
selecting a set of gears in view of a desired gear ratio between the valve drive shaft and the tap drive shaft; and subsequent to assembling the valve and the handle, removably mounting the gears on the respective tap drive shaft or valve drive shaft, such that the gear wheels interact.

9. A tap for dispensing a beverage comprising, a housing defining a dispensing channel for dispensing a beverage, a valve arranged in the housing allowing opening and closing a dispensing channel, said valve operable by a handle and a gear transmission between the valve and the handle, characterized in that the gear transmission has a variable gear ratio defining the ratio between the rotation angle of the handle and the rotation angle of the valve, whereby replacing a first gear driven by the handle or a second gear driving the valve with a gear of a different diameter modifies the gear ratio of the gear transmission and the valve actuation rate upon rotating the handle.

10. The tap according to claim 9 , wherein the gear transmission comprises two gear systems with different gear ratio, the handle configured to couple to either of the two gear systems.

11. The tap according to claim 10 , the gear transmission comprising two planetary gear systems with different gear ratio.

12. The tap according to claim 11 , wherein the planetary systems are mounted offset around a valve's axis of rotation at opposite sides of the valve.
