Valve for filling bottles etc. under pressure, especially drinks - has spring which moves gas pipe downwards while valve remains closed, and cam acting on second spring then causes valve to open

摘要

A spring (18) presses the gas pipe (15) and the spindle (8) in opposite directions. In the closed position of the valve, the gas pipe is held against an upper stop (22) on the spindle. A second stronger pipe (25) is provided on the spindle. A downward movement of the cam (13) releases the gas pipe so that it is moved downwards by the first spring while the spindle remains in its closed position. A further movement of the cam acts on the second spring against the force of the first spring and moves the spindle into its open position. USE/ADVANTAGE - For filling drinks bottles cans etc. The control is simplified without the need to use a piston and cylinder arrangement.
