<p>A carbon dioxide gas pressure regulator for an effervescent beverage container, regulating the pressure in the effervescent beverage-containing container according to temperature of the beverage. The regulator has an electronic control unit, a stepping motor, and a pressure regulation plate. The electronic control unit has a control map where a relationship between temperature and supply pressure of the carbon dioxide gas is inputted, calculates, based on the control map, the supply pressure of the carbon dioxide gas corresponding to the temperature detected by a temperature sensor, and outputs a signal corresponding to the supply pressure. The stepping motor is rotated corresponding to the signal outputted from the electronic control unit. The pressure regulation plate is driven by the rotation of the stepping motor and extends and retracts a pressure regulation spring. The pressure of the carbon dioxide gas is regulated to an optimum pressure according to the temperature of the effervescent beverage, so that the beverage has the same good taste every time it is dispensed.</p> |
