The pressurized COgas source is an insert which can be attached with sealing in an orifice of the vessel. The insert has a high-pressure COcartridge (14), a pressure control valve for delivering COtherefrom and a rotary knob (24) accessible from the outside. The rotary knob (24) interacts with an axial pusher (40), actuation of which allows the high-pressure COcartridge (14) to be pierced by a piercing needle (34). |
