Abstract
In a liquid carbonating apparatus a calibrated orifice (14) is included in the gas supply passage to limit the gas flow rate to a level below that at which gas can escape through a pressure relief valve. The surface has a diameter in the range 0.5-1.0 mm, pref. 0-7-0.9 mm. <IMAGE>
Description
SPECIFICATION
Liquid carbonating apparatus
This invention relates to apparatus for aerating liquids, and in particular an apparatus for carbonating water to prepare carbonated beverages.
In one known kind of liquid carbonating apparatus the liquid to be carbonated is placed into a bottle and the bottle is loaded into a carbonating machine.
A seal member is adapted to engage and seal closed the neck of the bottle, while a tube carrying a gas nozzle extends through the seal member and down into the bottle for injecting carbon dioxide gas into the liquid contained in the bottle. The upper end of the gas tube is connected to a gas cylinder via a valve which is connected to a gas cylinder via a valve which is operated manually to supply gas to the injection nozzle. With a view to limiting the maximum pressure within the bottle an exhaust passage is provided through the seal member and communicates with atmosphere through a relief valve which is arranged to open when a given pressure is exceeded. When the relief valve operates it produces an audible signal indicating to the operator that the gas valve should be closed to interrupt the supply of gas. In this way the relief valve limits the maximum pressure in the bottle.As an example of such a carbonating machine reference is made to International Patent Publication
No. W084/04024.
In general the carbonating apparatuses of the above kind currently available on the market operate satisfactorily. However, so as to ensure maximum possible safety to a person using the machine it is necessary to eliminate as far as possible any risk of a bottle becoming over pressurised and bursting in the machine.
With this aspect of safety in mind the present invention provides an apparatus for carbonating liquid, comprising a nozzle for injecting gas into a body of liquid to be carbonated, a gas supply passage for conducting gas to the nozzle from a source of gas, a relief valve arranged to-open at a given pressure for communicating a gas space above the body of liquid with atmosphere, and a calibrated orifice included in the gas supply passage to limit the gas flow rate to a level not greater than that at which gas can escape from said space through the relief valve.
The calibrated orifice proposed in accordance with the invention will ensure that the pressure within a bottle containing the liquid being carbonated will not rise above the maximum set by the relief valve, even if the injection nozzle should become connected to the cylinder for constant flow of gas under the full cylinder pressure, e.g. if the gas valve were to stick in a fully open position.
The calibrated orifice is preferably provided in a separate part inserted into the apparatus, which facilitates manufacture since the orifice can be formed to close tolerances in a separate component to other parts of the apparatus. Conveniently the orifice is provided in a part which is fastened to the inlet end of a gas tube which carries the nozzle.
For a liquid carbonating apparatus of the known kind mentioned hereinabove, the calibrated orifice should preferably have a diameter not greaterthan 1.0 mm. In order that it should not impose too great a restriction on the gas flow and thereby interfere with the normal operation of the apparatus, it is preferred that the orifice have a diameter of not less than 0.5 mm. An ideal size for the orifice diameter is believed to be in the range of 0.7 mm to 0.9 mm.
Although specifically described herein applied to a carbonating machine in which the liquid to be carbonated is held in a bottle, the invention is also applicable to a machine incorporating a chamber into which the liquid is poured and from which the carbonated liquid is discharged through a valve controlled outlet. The use of a calibrated orifice in such a machine helps to ensure that the chamber pressure will not exceed the intended maximum.
To assist a better understanding of the invention one exemplary embodiment will now be described in more detail with reference being made to the accompanying drawing which is a front elevation, shown partly in cross-section, of part of a liquid carbonating machine according to the invention.
The machine illustrated in the drawing is, except for the modification mentioned below, exactly the same as that described in International Patent
Application Publication No. W084/04024 to which reference should be made for a full description of the construction and operation of the machine. The contents of said publication No. W084/04024 are incorporated herein by way of reference.
Water to be carbonated is placed into a bottle, such as that denoted by numeral 2 in the drawing, and the bottle is then loaded into the machine in which it is supported buy a bayonet type connection at the bottle neck. Gas is delivered into the water through a nozzle 4 carried at the lower end of a gas tube 6 which extends down into the bottle. The gas is supplied to the upper end of the gas tube from the gas cylinder under the control of a manually operated valve and through a passage which opens into a chamber 8 above a piston 10 which carries the gas tube 6. The piston 10 is driven down under the gas pressure in the chamber 8 to move a seal 12 into engagement with the bottle neck.
In accordance with the modification of the present invention, a port 14 in the piston communicating the chamber 8 with the gas tube 6, is designed as a calibrated orifice which determines the rate of flow of gas to the nozzle 4. Furthermore, the calibrated orifice restricts the maximum flow rate to a level below that at which gas can flow out of the bottle 2 via an exhaust passage and a pressure relief valve connected to this passage. The exhaust passage includes an annular duct defined between the gas tube and piston, a radiai hole 16 in the piston and a chamber 18 above a diaphragm interconnecting the piston with the surrounding support structure. A diameter of 0.5 to 1.0 mm, and more preferably 0.7 to 0.9 mm has been found appropriateforthe orifice 14. By means of the orifice it is ensured that the pressure in the bottle will not rise above the maximum set by the relief valve, even if the gas valve were to stick fuily open so that the gas was free to flow from the cylinder constantly at the full cylinder pressure. Thereby the safey of the machine is significantly enhanced.
It will be understood that the invention is applicable to carbonating machines other than that specifically described, and that the exact location of the calibrated orifice to determine the maximum flow rate between the gas cylinder and the injection nozzle is not important.
