DEVICE FOR DISPENSING A FLUID FROM A CAVITY OF A CONTAINER

摘要

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.
