[0007] According to a preferred embodiment, the mixing nozzle comprises a body, the liquid inlet port and the gas inlet port being formed on said body.
[0008] According to a preferred embodiment, the liquid inlet port and the gas inlet port are arranged on a frontal transversal face of the body.

[0010] According to a preferred embodiment, the fluid connection between the gas inlet port and the at least one radial passage comprises: an inlet passage extending directly downstream from the gas inlet port; and at least one transversal passage interconnecting the inlet passage and the at least one radial passage.
[0011] According to a preferred embodiment, the contact interface is planar or comprises several parallel planes.
[0012] According to a preferred embodiment, each of the two shells comprises an inner surface forming a cavity mating with the device for mixing gas with liquid. [0013] According to a preferred embodiment, each of the two shells is made of thermal insulation material, preferably a foam material, more preferably expanded polystyrene.
[0014] According to a preferred embodiment, the unit further comprises: a cooling device with a cooling conduit, a cooling inlet port and a cooling outlet port, said cooling device being encapsulated in the housing.
[0015] Advantageously, the unit comprises several cooling devices each with a cooling conduit, a cooling inlet port and a cooling outlet port, said cooling device being encapsulated in the housing. The cooling inlet ports can be common, i.e. single for the several cooling devices. The same applies to the cooling outlet ports.
[0016] According to a preferred embodiment, the cooling inlet port and the cooling outlet port are located at the contact interface.
[0017] According to a preferred embodiment, the cooling inlet port and the cooling outlet port are located on opposed faces of the housing.
[0018] According to a preferred embodiment, the cooling conduit is thermally coupled to the device for mixing gas with liquid.
[0019] According to a preferred embodiment, the housing forms at least one thermally coupling chamber between the conduit and the device for mixing gas with liquid.
[0020] According to a preferred embodiment, the at least one thermally coupling chamber comprises several elongate thermally coupling chambers extending transversally to the cooling conduit and the device for mixing gas with liquid.

[0024] Advantageously, the unit for mixing gas with liquid comprises more than one device for mixing gas with liquid, e.g. two or three of said devices for mixing gas with liquid. These devices for mixing gas with liquid can be arranged side by side in the housing. The cooling device, if present, is advantageously common for the several devices for mixing gas with liquid, i.e. thermally coupled thereto.
[0025] The invention can be directed to a serving fount comprising at least one tubular upright, at least one serving tap at the upper end of the tubular upright, and a unit for mixing gas with liquid housed in the at least one tubular upright.
Advantages of the invention
[0026] The invention is particularly interesting in that it provides an encapsulated unit for mixing gas with liquid that is compact, well insulated and easy to assemble. A performing insulation is particularly interesting in that low temperatures increase gas dissolution into liquids. It is therefore advantageous to keep the device for mixing gas with liquid, for instance the nozzle and more particularly the mixing chamber, as low temperature, even if the beverage dispensing machine to which the unit for mixing gas with liquid is intended to be mounted comprises a beverage cooling unit, even downstream of said unit. Assembly is also facilitated in that the unit for mixing gas with liquid can be totally free of curved hose inside the housing, meaning that only rigid elements such as the nozzle and the mixing chamber are to be placed in the housing. When the unit for mixing gas with liquid comprises a cooling device, the conduit of the latter can be rigid or at least comprise only straight portions, so that positioning the cooling device in the housing is as much easy as for positioning the device for mixing gas with liquid.

Description of an embodiment [0030] Figure 1 illustrates a unit for mixing gas with liquid, according to a first embodiment of the invention.
[0031] The lower image is an elevation view of the unit for mixing gas with liquid, the top left image is an A-A sectional view and the right image is a B-B sectional view.
[0032] The unit for mixing gas with liquid 2 comprises a device for mixing gas with liquid 4 and a housing 6 encapsulating said device. More specifically, the housing 6 comprises two shells 6.1 and 6.2 which are joined to each other along a contact interface 6.3 that is preferably planar. That contact interface 6.3 corresponds for instance to the longitudinal plane of the B-B section, being however understood that it could be off-set relative to and/or secant with that longitudinal plane. The two shells 6.1 and 6.2 correspond essentially to two half-shells that mate with reach other along the contact interface 6.3. Each shell 6.1 and 6.2 comprises an inner surface forming a cavity mating with the device for mixing gas with liquid 4. There is therefore no play or at least no substantial play between the resulting cavity and the device for mixing gas with liquid 4.
[0033] Each shell 6.1 and 6.2 is made of thermally insulating material, e.g. foam material like expanded polystyrene. They are advantageously formed by moulding and made of plain material between the inner surface and the outer surfaces. Once joined to each other while enclosing the device for mixing gas with liquid 4, they can be secured to each other by various means, like protrusions extending from one shell and engaging in corresponding holes in the other shell.
[0034] The device for mixing gas with liquid 4 comprises a nozzle 8 and a mixing chamber 10 attached thereto and located downstream. The nozzle 8 comprises a body 8.1 with a liquid inlet port 8.2 and a gas inlet port 8.3. Both are advantageously arranged on a frontal transversal face of the body 8.1. The body 8.1 forms an inlet passage 8.4 extending directly downstream from the gas inlet port 8.2, and showing a progressively reducing cross- section and downstream thereof a progressively increasing cross-section to an outlet 8.5 of the nozzle. The body 8 further forms two transversal passages 8.6 interconnecting a gas inlet passage 8.7, downstream of the gas inlet port 8.3, and two radial passages 8.8. [0035] The nozzle 8 forms at the nozzle outlet 8.5 a connection ring 8.9, which could be shaped differently, like with a flange, that engages with the mixing chamber 10. The latter comprises a cylindrical wall 10.1 provided with an inlet end 10.2 engaging with the connection ring 8.9. The mixing chamber 10 can comprise one or more baffles 10.3 for receiving, dampening and redirecting the flow of gas enriched liquid from the nozzle, so as to lengthen its remaining time in the mixing chamber 10.
[0036] The mixing chamber 10 comprises at an outlet end of the cylindrical wall 10.1 a liquid outlet port 10.4.
[0037] As this apparent, each of the liquid inlet port 8.2, the gas inlet port 8.3 and the liquid outlet port 10.4 is located at the contact interface 6.3 between the two shells 6.1 and 6.2 of the housing 6. This means in practice, that the device for mixing gas with liquid 4, once assembled, can be placed in the cavity of a first one of the shells 6.1 and 6.2, with each of the liquid inlet port 8.2, the gas inlet port 8.3 and the liquid outlet port 10.4 positioned adjacent to the outer surface of the first shell 6.1 or 6.2. The second shell of the shells 6.2 and 6.1 is then joined to the first shell 6.1 or 6.2, thereby mating with the remaining part of the device for mixing gas with liquid 4 and with the first shell 6.1 or 6.2 along the contact interface 6.3.
[0038] In operation, the unit for mixing gas with liquid 2 works as follows. A source of liquid, e.g. water or any other beverage like coffee, wine, cocktails, etc. is fed under pressure to the liquid inlet port 8.2. In parallel, compressed gas that is able to dissolve in the liquid, like carbon dioxide, nitrogen or air, is fed to the gas inlet port 8.3. The liquid outlet port 10.4 is fluidly connected to a dispensing device or installation, like a serving tap. Once that tap is opened, the liquid flows along the inlet passage 8.4 to the reduced cross- section, at the level of the radial passages 8.8 fed with the compressed gas. The venturi effect caused by the reduced cross-section accelerates the liquid and diminishes its pressure. The gas under pression can then flow radially into the inlet passage 8.4 and mixes with the liquid. The flow of liquid decelerates in the diverging passage at the outlet 8.5 of the nozzle 8 and flows at a lower speed along the mixing chamber 10. During that lapse of time, the gas progressively dissolves in the liquid, so that the liquid output at the liquid outlet port 10.4 is properly mixed with gas. The above functioning principle is as such known and does not need to be further detailed.
[0039] The construction of the device for mixing gas with liquid 4, as detailed above and illustrated in figure 1 is particularly adapted for being enclosed in the housing 6 in that it shows a compact design in a transversal direction, leaving space for insulation material of the housing 6. It is also particularly adapted for being enclosed in the housing 6 in that the liquid inlet port 8.2, the gas inlet port 8.3 and the liquid outlet port are provided directly on the device for mixing gas with liquid 4, i.e. on the body 8.1 of the nozzle 8 and on the cylindrical wall 10.1 of the mixing chamber. This means that the device for mixing gas with liquid 4, once assembled, can be directly placed in the housing 6 without any need to position hoses or the like of said device.
[0040] It is understood that the gas inlet portion 8.3 could be positioned distant from the liquid inlet port 8.2, e.g. at a radially position. Also, two gas inlet ports can be provided at opposed radial positions and be located at the contact interface between the shells 6.1 and 6.2.
[0041] Figure 2 illustrates a unit for mixing gas with liquid, according to a second embodiment of the invention.
[0042] The lower image is an elevation view of the unit for mixing gas with liquid and the top image is an A-A sectional view.
[0043] The reference numbers of the first embodiment are used designating the same or corresponding elements of the second embodiments, these numbers being however incremented by 100. It is also referred to the description of these elements in the first embodiment. Specific reference numbers comprised between 100 and 200 are used for designating specific elements of that second embodiment.
[0044] The unit for mixing gas with liquid 102 of this second embodiment differs from the one of the first embodiment essentially in that it comprises a cooling device 112 with a cooling conduit 112.1 , a cooling inlet port 112.2 and a cooling outlet port 112.3, said cooling device 112 being encapsulated in the housing 106. Each of the cooling inlet port 112.2 and the cooling outlet port 112.3 is located at the contact interface 106.3 between the two shells 106.1 and 106.2. [0045] For instance, the cooling device 112 in that the cooling conduit 112.1 is straight, so that the cooling inlet port 112.2 and the cooling outlet port 112.3 is located on opposed faces of the housing 106.
[0046] The cooling conduit 112.1 is thermally coupled to the device for mixing gas with liquid 4 via two thermally coupling chambers 106.4 and 106.5. Each thermally coupling chamber 106.4 and 106.5 is in contact with the cooling conduit 112.1 and with the device for mixing gas with liquid 104, and is filled with ambient air. More specifically, the thermally coupling chamber 106.4 extends transversally and contacts the nozzle 108, for instance the body 108.1 thereof, whereas the thermally coupling chamber 106.5 extends also transversally but contacts the mixing chamber 110, for instance the cylindrical wall 10.1 thereof. The air located in these thermally coupling chambers achieves a heat transfer by natural convection. It is also to be noted these chambers can surround at least partly each of the cooling conduit 112.1 and the device for mixing gas with liquid 104, in order to increase the contact surface therewith and thereby the thermal coupling.
[0047] The thermally coupling chambers 106.4 and 106.5 are directly formed in the shells 106.1 and 106.2 of the housing, i.e. as cavities similarly to the cavities receiving the device for mixing gas with liquid 104 and the cooling device 112. This further renders the assembly operations in that the thermal coupling is achieved by placing the device for mixing gas with liquid 104 and the cooling device 112 into their respective cavities in the shells 106.1 and 106.2.
[0048] It is however to be noted that the thermal coupling can be achieved by other means, e.g. by one or several connecting elements or bars advantageously made of thermally conductive material which can be metal or even plastic material like polyamide. Each such connecting element or bar can also be provided with clamping ends for providing a sufficient contact surface and/or contact pressure with each of the device for mixing gas with liquid 104 and the cooling conduit 112.1.
[0049] The cooling device 112 is advantageously fed with cooled water, being however understood that other fluids can be considered. [0050] It is also to be understood that the cooling conduit 112.1 of the cooling device 112 does not need to be straight, i.e. it can show bends and/or even contact the device for mixing gas with liquid 104.
[0051] Figure 3 illustrates a unit for mixing gas with liquid, according to a third embodiment of the invention.
[0052] The lower image is an elevation view of the unit for mixing gas with liquid, the top left image is an A-A sectional view and the top right image is a B-B sectional view.
[0053] The reference numbers of the second embodiment are used designating the same or corresponding elements of the second embodiments, these numbers being however incremented by 100. It is also referred to the description of these elements in the first embodiment. Specific reference numbers comprised between 200 and 300 are used for designating specific elements of that third embodiment.
[0054] The unit for mixing gas with liquid 202 of this third embodiment differs from the one of the second embodiment essentially in the design of the cooling device 212.
[0055] The cooling device 212 comprises a cooling conduit 212.1 that is generally U-shaped and comprised of a first conduit 212.1.1, a second conduit 212.1.2 parallel to the first conduit, a first connector 212.1.3 and a second connector 212.1.4 cooperating with the first connector for fluidly connecting the first and second conduits 212.1.1 and 212.1.2.
[0056] Similarly to the second embodiment, the cooling conduit 212.1 is thermally coupled to the device for mixing gas with liquid 204 via a thermally coupling chamber 206.4 filled with ambient air. That thermally coupling chamber 206.4 is formed by two opposed and corresponding cavities 206.1.1 and
206.2.1 formed in the shells 206.1 and 206.2 respectively. Contrary to the second embodiment, the cooling inlet port 212.2 and the cooling outlet port 212.3 are not located in the contact interface 206.3 but rather in specific cavities opening out to the outside.
[0057] The first and second connectors 212.1.3 and 212.1.4 of the cooling conduit
212.1 are designed for engaging with each other in a fluid tight manner when assembling the shells 206.1 and 206.2 with each other, i.e. in a direction that is transversal, preferably perpendicular, to the contact interface 206.3. For instance, each of the first and second connectors 212.1.3 and 212.1.4 forms a bend at 90°. With reference in particular to the top right image in figure 3, the assembly operations of the cooling devices are as follows: each of the first and second conduits 112.1.1 and 112.1.2, provided with the cooling inlet port 212.2 and the cooling outlet port 212.3, respectively, is inserted from outside into to the corresponding cavities and holes formed in the shells 206.1 and 206.2. Thereafter, each of the first and second conduits 112.1.1 and 112.1.2 is engaged in the corresponding one of the first and second connectors 212.1.3 and 212.1.4. The shells 206.1 and 2062 can then be assembled to each other while taking care that the first and second connectors 212.1.3 and 212.1.4 mutually engage.
[0058] Generally, the ports for the liquid inlet, gas inlet, liquid outlet, cooling inlet and cooling outlet, mentioned here above are commercially available quick connectors for hoses.
[0059] Also generally to the embodiments in figures 2 and 3, the unit can comprise several of the cooling units.
[0060] Further generally, the unit for mixing gas with liquid according to the invention can be housed in a serving fount, in particular in a tubular upright of such a serving fount. This provides the advantage of being very close to the dispensing points at the tap(s) usually located at the upper end of the at least one tubular upright.
