ABSTRACT:
Disclosed is a device for dispensing a fluid, in particular a carbonated beverage, from a storage chamber of a container towards the outside via at least one closeable discharge port, comprising a pressure reservoir which is separated from the storage chamber and in which a pressurized propellant is accommodated, and which can be connected to the storage chamber via a pressure regulation mechanism. The pressure regulation mechanism includes an axially moveable regulating element that is impinged upon by means of a spring in the direction of an open position in which propellant is discharged from the pressure reservoir into the storage chamber. The ambient pressure to which the container is exposed acts upon the regulating element in the direction of the open position, and the internal pressure inside the storage chamber of the container acts upon the regulating element in the direction of the closed position.
