Disclosed is a device for dispensing a fluid, in particular a carbonated beverage, from a storage chamber (15) of a container (12) towards the outside via at least one closeable discharge port (14), comprising a pressure reservoir (16) which is separated from the storage chamber (15) and in which a pressurized propellant is accommodated, and which can be connected to the storage chamber (15) via a pressure regulation mechanism (17, 17'). The pressure regulation mechanism (17) includes an axially moveable regulating element (30) that is impinged upon by means of a biasing means (38) in the direction of an open position in which propellant is discharged from the pressure reservoir (16) into the storage chamber (15). The ambient pressure to which the container (12) is exposed acts upon the regulating element (30) in the direction of the open position, and the internal pressure inside the storage chamber (15) of the container (12) acts upon the regulating element (30) in the direction of the closed position.

La présente invention concerne un dispositif pour faire sortir un liquide, en particulier une boisson gazeuse, de l'espace de stockage (15) d'un récipient (12), par au moins une ouverture de sortie refermable (14), ledit dispositif comprenant un réservoir pressurisé (16) séparé de l'espace de stockage (15), dans lequel se trouve un agent propulseur sous pression, ledit réservoir pouvant être relié à l'espace de stockage (15) par un mécanisme de régulation de pression (17). Le mécanisme de régulation de pression (17) présente un organe de régulation mobile (30) qui se présente de préférence sous la forme d'une membrane à laquelle un élément de précontrainte (38) applique une contrainte en direction de la position d'ouverture dans laquelle l'agent propulseur est expulsé hors du réservoir pressurisé (16) vers l'intérieur de l'espace de stockage (15), la pression ambiante qui agit sur le réservoir (12), agissant sur l'organe de régulation (30) dans la direction de la position d'ouverture, et la pression interne dans l'espace de stockage (15) du récipient (12), agissant sur l'organe de régulation (30) dans la direction de la position de fermeture.
