Description

Description VALVE WITH SHUTTER MOUNTER FROM THE INLET SIDE FOR CO2
CARTRIDGE Technical field
[0001] The invention is directed to the field of gas valves, more particularly gas valves for cartridges containing compressed gas, in particular for drink gas enrichment machines.
Background art
[0002] Prior art patent document published EP 2 772 710 A2 discloses a water carbonation system integrated in a refrigerator. The carbonation system is supplied with compressed CO» gas by means of a cartridge that is coupled to the carbonation system via a quick coupling means. The latter consists essentially of a lever and a holder pivotally connected to the lever and provided with two hooks for engaging with two radially oriented opposed pins on the top of the cartridge. The two radially oriented opposed pins are formed on a connector that is screwed on the outlet portion of a valve mounted on the neck of the cartridge. The valve is not detailed in that document.
[0003] Instead of the two radially oriented opposed pins and the lever mechanism, it also known to provide on the valve a trapezoidal outer thread of the Acme type, i.e. with a high pitch, allowing engagement between the cartridge and the carbonation system by a rotational movement with a limited number of turns compared with a classical fastening/mounting thread.
[0004] Gas valves mounted on the neck of compressed CO, cartridges for carbonation machines have usually their shutter mounted in the body from the outlet side, essentially because the shutter is close to the outlet for being pushed downwardly by the carbonation machine during operation. This however weakens the body of the gas, in particular the means for quick engagement with the carbonation machine, for these means are located on the outlet portion of the body.
Summary of invention Technical Problem
[0005] The invention has for technical problem to overcome at least one drawback of the above-mentioned prior art. More specifically, the invention has for technical problem to provide a valve for compressed gas cartridges that is more robust and/or cheaper while enabling a quick engagement with a drink gas enrichment machine.
Technical solution
[0006] The invention is directed to a valve for a cartridge containing compressed gas for a drink gas enrichment machine, the valve comprising a body comprising an inlet portion for engaging with a connecting neck of the cartridge; an outlet portion with means for quick engagement with the drink gas enrichment machine; and a gas passage formed in the body and fluidly interconnecting the inlet portion and the outlet portion; a shutter urged by a spring against a seat, in a gas passage closing position, and movable to a gas passage opening position by exerting an external force on the shutter, against the spring and through the outlet portion; remarkable n that the inlet portion comprises a bore into which the shutter and spring are inserted from an inlet side.
[0007] According to a preferred embodiment, the means for quick engagement comprises a trapezoidal outer thread or two radially oriented opposed pins.
[0008] According to a preferred embodiment, the valve further comprises an abutment ring attached to inlet portion of body, the spring having a first end resting on the shutter and a second opposed end resting on the abutment ring.

[0010] According to a preferred embodiment, the shutter further comprises an annular gasket housed in an external circular groove of the pin, adjacent the cylindrical element, the annular gasket being configured for contacting a seat formed in the body in the gas passage closing position of the shutter.
[0011] According to a preferred embodiment, the cylindrical element comprises an annular end wall surrounding the annular gasket and configured for limiting a deformation of the annular gasket, in the gas passage closing position of the shutter by abutting against the seat.
[0012] According to a preferred embodiment, the bore shows a constant diameter from the seat to the abutment ring.
[0013] According to a preferred embodiment, the second end of the pin extends in an open cavity at the outlet portion of the body, the open cavity being integrally formed with the body.
[0014] According to a preferred embodiment, the open cavity comprises an inner groove housing a gasket distant from the pin.
[0015] According to a preferred embodiment, the bore extends totally through the inlet portion of the body and partly through the outlet portion of the body.
[0016] According to a preferred embodiment, the means for quick engagement comprises two radially oriented opposed pins.
[0017] According to a preferred embodiment, the two radially oriented opposed pins are integrally formed with the body.
[0018] According to a preferred embodiment, the outlet portion of the body has a cylindrical outline with recesses.
[0019] According to a preferred embodiment, the outlet portion of the body has a cross-shaped cross-section formed by the recesses.
[0020] According to a preferred embodiment, the two radially oriented opposed pins are aligned with one of two main directions of the cross-shaped cross- section.
[0021] According to a preferred embodiment, the inlet portion of the body is directly adjacent to the outlet portion of the body.

[0023] According to a preferred embodiment, the body comprises an intermediate portion between the inlet portion and the outlet portion, the intermediate portion having at least two parallel outer flat surfaces allowing engagement in rotation with a tightening/untightening tool.
Advantages of the invention
[0024] The invention is particularly interesting in that it provides a valve that is more robust at its outlet side and is cheaper to manufacture, notably in that no gas tight barrier is to be built as when mounting the shutter from the outlet side. The shutter is indeed located on an upstream side of its corresponding seat, so that the gas pressure naturally presses the shutter against the seat and closes the gas passage. Mounting the shutter from the outlet side requires then the seat to be on a separate part to be mounted on the body. This requires therefore special care in building a gas tight barrier between the seat and the body, e.g. in providing threads and appropriate gaskets. Also, the absence of such elements allows the outlet portion of the body to show more plain material, higher wall thicknesses between the gas passage and the means for quick engagement with the drink gas enrichment machine.
[0025] The invention in the configuration where the means for quick engagement with the drink gas enrichment machine is integrally formed with the body is also advantageous in that it simplifies the constructions and renders the valve more reliable.
Brief description of the drawings
[0026] Figure 1 illustrates a valve according to a first embodiment of the invention, with a plan view, a sectional view and a top view.
[0027] Figure 2 illustrates a valve according to a second embodiment of the invention, with a plan view, a sectional view and a top view.
Description of an embodiment
[0028] Figure 1 illustrates a valve according to a first embodiment of the invention. The top left view is a plan view of the valve, the top right view is a cross-section A-A of the valve in the plan view, and the bottom view is a top view of the valve in the plan view.
[0029] The valve 2 comprises a body 4, which itself comprises an inlet portion 4.1 and an outlet portion 4.2. A gas inlet 6 is formed at the inlet portion 4.1 and a gas outlet 8 is formed at the outlet portion 4.2. The gas inlet 6 and gas outlet 8 are fluidly interconnected by a gas passage 10 formed in the body
4.
[0030] The inlet portion 4.1 of the body 4 is provided with an outer thread for engaging with a corresponding inner thread of a neck of a gas cartridge. The latter is not illustrated for it is widely used and known from the skilled person. The outlet portion 4.2 is directly adjacent to the inlet portion 4.1. For instance, it forms a shoulder onto which a gasket 12 rests for forming a gas tight barrier with the upper edge of the neck of the gas cartridge.
[0031] A bore 14 is formed in the body 4, opening out at the gas inlet 6. The bore 14 extends longitudinally completely along the inlet portion 4.1 and partly along the outlet portion 4.2. The bore 14 houses a spring 16 and a shutter 18 urged by the spring 16 against a seat 4.2.1 formed for instance in the body 4, in particular in the upper portion 4.2 thereof. An abutment ring 20 is attached to the body 4, in this particular example it is housed in the bore 14 and attached thereto by a threaded engagement with the bore 14. It is understood that other configurations can be considered, e.g. the attachment can be by crimping and the abutment ring does not need to be housed in the bore 14, i.e. can be at least partially or totally outside thereof. Also, the abutment ring can be replaced by other retaining means, like a pin extending radially through the bore, etc. In any case, the shutter 18 and the spring 16 are mounted on the body 4 by insertion into the bore 14 from the inlet side of the valve.
[0032] The shutter 18 can comprise a cylindrical element 18.1 with a blind-hole, and a pin 18.2 with a first and lower end located in the blind-hole and a second and upper end extending towards the outlet portion 4.2 of the body
4. The first and lower end of the pin 18.2 is advantageously press-fitted into the bling-hole, being however understood that other fastening means can be considered, like a threaded engagement. The shutter 18 further comprises an annular gasket 18.3 housed in an external circular groove of the pin 18.2, adjacent the cylindrical element 18.1, the annular gasket 18.3 being configured for contacting the seat 4.2.1 in a position that closes the gas passage 10. The cylindrical element 18.1 can comprise an annular end wall 18.1.1 surrounding the annular gasket 18.3 and configured for limiting a deformation of the annular gasket 18.3 when the shutter 18 is in the gas passage closing position, by abutting against the seat 4.2.1.
[0033] The second and upper end of the pin 18.3 extends in an open cavity 4.2.2 formed in the outlet portion 4.2 of the body 4, and whose opening from the the gas outlet 8. As this is apparent, the open cavity 4.2.2 is integrally formed with the body 4. The open cavity 4.2.2 can be provided with an inner groove housing a gasket 22 distant from the pin 18.3 and configured for cooperating in a gas tight fashion with a shaft of the drink gas enrichment machine.
[0034] The upper portion 4.2 of the body 4 carries two radially oriented opposed pins 24 which are configured for engaging with corresponding hooks of a lever mechanism as described in above background section. These two radially oriented opposed pins 24 are advantageously unitary with the upper portion 4.2 of the body 4.
[0035] The upper portion 4.2 of the body 4, although showing a generally cylindrical outline, is provided with recesses 4.2.3 on the lateral outer surface and on the top surface. These recesses 4.2.3, for instance four recesses, form a cross-shaped cross-section 4.2.4 of the upper portion 4.2 of the body 4. As this is apparent, the two radially oriented opposed pins 24 are advantageously aligned with one of the two main directions of the cross-shaped cross-section 4.2.4. The recesses 4.2.3 resulting in the cross-shaped cross-section 4.2.4 are interesting in that they substantially reduce the amount of material while keeping enough rigidity. The material is advantageously brass where the recesses 4.2.3 and the two radially oriented opposed pins 24 are forged and/or stamped. This means that the recesses 4.2.3 provide a direct reduction of material used for the valve. Also, the generally cylindrical outline of the upper portion 4.2 serves as guiding surface during engagement of the valve with the drink gas enrichment machine. As this is apparent, the recesses 4.2.3 can extend longitudinally downwardly until the two radially oriented opposed pins 24, i.e. until close to their axis.
[0036] The valve 2 can also comprise a pressure relief device 26 that, for instance, is formed by a hollow plug gas tightly engaged in the body 4 and provided with a burst passage that ruptures and opens when the pressure in the gas cartridge and therefore in the bore 14 exceeds a predetermined level. The pressure relief device 26 is provided on the outlet portion 4.2 of the body 4.
[0037] The valve 2 can also be provided with a pressure relief passage 28 on the inlet portion 4.1 of the body 4, connecting the bore 14 with the outside, however below the gasket 12. This allows a residual pressure in the gas cartridge to be released after starting to unscrew the valve 2, i.e. before the valve is totally unscrewed. This thereby prevents the valve 2 from being ejected by the residual gas pressure, at the end of unscrewing.
[0038] Figure 2 illustrates a valve according to a second embodiment of the invention. The top left view is a plan view of the valve, the top right view is a cross-section A-A of the valve in the plan view, and the bottom view is a top view of the valve in the plan view.
[0039] The reference numbers of used in figure 1 for the first embodiment are used here in figure 2 for the same or corresponding elements, these numbers being however incremented of 100. It is also referred to the description of these elements.
[0040] The valve 102 in figure 2 differs from the valve 2 in figure 1 essentially in that the two radially oriented opposed pins 24 (figure 1) are replaced by a trapezoidal outer thread 124, e.g. of the Acme form. The Acme thread form has a 29° thread angle with a thread height half of the pitch.
[0041] The valve 102 of the second embodiment differs also from the valve of the first embodiment in that the body 4 comprises an intermediate portion
104.3 between the inlet portion 104.1 and the outlet portion 1004.2, the intermediate portion 104.3 having at least two parallel outer flat surfaces allowing engagement in rotation with a tightening/untightening tool. In the present example, the intermediate portion 104.3 provide a hexagonal outer profile, being understood that it could be a square profile or even a profile with only two parallel outer flat surfaces.
[0042] It is however understood that the valve according to the first embodiment could be provided with an intermediate body portion as in the second embodiment. However, the presence of the two radially oriented opposed pins 24 (figure 1) provides a practical gripping shape for tightening and untightening the valve in rotation, so that such an intermediate body portion might be unnecessary.
