Abstract: Impregnating device (20) comprises: an impregnator, preferably inline-carbonator, in which an impregnating gas e.g. carbon dioxide and an impregnating gas-free or -poor beverage precursor e.g. pure or drinking water staggered with a lemonade syrup, or a carbonated-free or -poor beer precursor, preferably beer precursor is supplied to control a beverage to be bound in the impregnator; a positive displacement pump, where the beverage precursor is conveyed to the impregnator, and pressure pulsations are induced in the beverage precursor; and a dosing device. Impregnating device (20) comprises: an impregnator, preferably inline-carbonator, in which an impregnating gas including carbon dioxide and an impregnating gas-free or -poor beverage precursor including pure or drinking water staggered with a lemonade syrup, or a carbonated-free or -poor beer precursor, preferably beer precursors with a maximum of 1 g carbon dioxide/l is supplied, to control a beverage including beer, lemonade or soda water to be bound in the impregnator, and thus to abandon the exit from the impregnator; a positive displacement pump, which is formed as a membrane pump, and the beverage precursor is conveyed to the impregnator, and thus pressure pulsations are induced in the beverage precursor; and a dosing device for dosing the impregnating gas supplied into the impregnator in a ratio for binding with the beverage precursor, where the dosing device comprises an impregnating gas-injecting valve, where a high impregnating gas flow is allowed in an open position, and a low or no flow of impregnating gas is allowed and operated in a blocked position, and a valve operating device. The valve operating device is coupled with a driving side of the positive displacement pump for synchronized operation of the impregnating gas-injecting valve during the pressure pulsations in the beverage precursor, to generate synchronized pulsations of impregnating gas mass flow supplied into the impregnator during the pressure pulsations in the beverage precursor. An independent claim is also included for a dispensing system (1) with an integrated production of a gas-containing, preferably carbon dioxide-containing beverage including beer, lemonade or soda water from a beverage precursor including carbon dioxide and an impregnating gas-free or -poor beverage precursor e.g. pure or drinking water staggered with a lemonade syrup, or a carbonated-free or -poor beer precursor, comprising: the impregnating device; an impregnating gas source, which provides the impregnating gas in a stationary manner under a constant pressure, and is connected with an inlet side of the impregnating gas-injecting valve; a beverage precursor source, preferably several unpressurized beverage precursor containers, where the beverage precursor source provides the beverage precursor at the release of over pressure or poor pressure, and is connected with a suction side of the positive displacement pump; and an operating fluid source, preferably operating gas source, which provides an over-pressurized stationary operating fluid, preferably operating gas to the displacement pump, and is connected with a driving side of the displacement pump.
