Definitions

  • This invention relates to portable apparatus for carbonating water, suitable for use for example in homes, offices, restaurants and bars.
  • the apparatus comprises a pressure vessel and a header tank, the vessel having a valved bottom inlet to admit fresh water from the header tank to the pressure vessel, a valved outlet in an upper region of the vessel for discharging carbonated water, and an injection nozzle for admitting CO 2 under pressure.
  • Fresh water is carbonated within the veseel and the outlet and inlet are opened to admit fresh water from a header tank to the bottom inlet, the fresh water displacing the carbonated water upwardly in the vessel and through the outlet.
  • This type of apparatus is described, for example, in British Patent Specification 392750 and was at one time in widespread use.
  • the present invention is primarily concerned with improving the valving arrangements in apparatus of the second category.
  • the inlet and outlet valve members take the form of poppet type, face sealing valves which are spring loaded against their respective valve seats. Because the valves must resist the pressure generated in the vessel during carbonation, it is necessary for the spring acting on the outlet valve to be sufficiently powerful to resist the pressure tending to blow the valve off its seating. This in turn means that a correspondingly large force must be applied to open the valve when the carbonated water is to be discharged, with the result that the apparatus may be difficult to operate by a woman or child, unless, of course, a somewhat complex mechanism is designed to provide a suitable mechanical advantage. The mechanism is in any case slightly complicated by the need to provide lost motion between the two valves, so that the outlet shall always be opened in advance of the inlet.
  • the primary object of the present invention is to improve the valving arrangements and overcome the above mentioned disadvantages.
  • the present invention accordingly provides portable apparatus for carbonating water, comprising a pressure vessel and a header tank, the vessel having a valved bottom inlet to admit fresh water from the header tank to the pressure vessel and a valved outlet in an upper region of the vessel for discharging carbonated water, and an injection nozzle for admitting C0 2 under pressure, and wherein the inlet and outlet valves take the form of pistons which are rigidly connected together to form a unitary plunger and have equal effective areas subjected to the pressure within the pressure vessel, whereby the plunger is substantially pressure balanced.
  • the plunger has an axial extension projecting from the vessel and connected to an operating lever.
  • the apparatus shown in the drawings comprises a casing 10, preferably formed by moulded plastics components housing a pressure vessel 11, a replaceable C02 cylinder 12 and a removable header tank 13 for containing a quantity of fresh water.
  • the vessel (see Figure 5) has a bottom inlet 34 connected to the water feed tube 26. Opening and closing of the inlet is controlled by an inlet valve piston 36, the lower portion of which is formed as a hollow skirt which is slotted in its upper region, so that in the raised position of the piston seen in Figure 4, the bottom inlet is open to the interior of the vessel.
  • the outlet at the upper end of the vessel comprises an axial valve bore 37 leading upwardly to an outlet spout 38.
  • the outlet valve comprises a sealed valve piston 39, having a neck 45 and a lower portion formed as a hollow skirt having a slot in its upper region, so that in the raised position shown in Figure 4, the interior of the vessel is in open communication with the outlet spout 38.
  • the two valve pistons are rigidly connected together for movement in unison by a connecting rod 40, so as to form a unitary plunger, which is extended axially upwardly, projecting from the vessel for connection to an operating lever 41, operation of which is described below.
  • the vessel 11 is, as is conventional, provided with a headspace 42 in which excess gas under pressure can accumulate.
  • the head space is .connected in known manner to a pressure relief valve 43 and at its upper end has a venting port 44 leading to the valve bore 37 at a level below the entrance to the discharge spout 38, to permit relief of the head space pressure in the manner described below.
  • the tank of the apparatus is conveniently dimensioned so as to permit the pressure vessel to be filled and its contents carbonated and discharged, six or seven times.
