Device for rapid connecting-up of pressurized containers in drinks dispenser plants

A device for rapid connecting-up of drink containers in drinks dispenser plants provided with a gas introduction line and a drink delivery line, comprising:

• a body of a head of the device having a cavity defining a three-way passageway, a first passageway is connectable to the gas introduction line, a second passageway connectable to the container and a third passageway connectable to the drink delivery line;
• a tubular element having a lateral wall and arranged in the cavity of the body such that the drink can flow from the second passageway into the third passageway while placing said lateral wall of said tubular element against the first passageway, said tubular element being associated with said cavity such as to be slidable along an axial direction thereof between a first and a second end run position, in one position the lateral wall prevents the introduction of a gas medium into a drink container, while in another position the gas can flow the second passageway and into the drink container, thereby forcing the drink from the drink container through the third passageway and into the drink delivery line;
• a drink intercept valve including a valve seat and an obturator, which said obturator is provided within said cavity of said body and rotatable relative to said valve seat for preventing said drink from flowing between the third passageway and the delivery line, which obturator is connected with said tubular element;
• a two-way command lever operatively connected with both said tubular element and said obturator;
• at least one mechanical link for interconnection of said obturator with said tubular element, said mechanical link contained internally of said body and comprising at least two elements which are each kinematically interconnected so as to be reciprocally roto-translatable within a portion of said body adjacent the tubular element, said first element being arranged parallel to said axial direction of said tubular element, said second element being rotatable along said first element and enmeshed with said obturator within said body adjacent said tubular element so as to impress thereon a rotation of said obturator, which rotation is correlated with a movement of said tubular element and said first and second elements by the actuation of said command lever, whereby such actuation defines said end run positions.
