Device, method and cluster for dispensing liquid to a water-soluble pouch and machine for forming and filling water soluble pouches

A method for dispensing liquid to water soluble pouches comprising:

• providing a device for dispensing liquid to a water soluble pouch, the device comprising:
• a fluid inlet;
• a fluid outlet;
• an elongated body defining a longitudinal axis of the device, the elongated body comprising a fluid passage therein extending from the fluid inlet to the fluid outlet;
• a fluidly actuated valve for opening and closing the fluid outlet, the valve comprising:
• a fluid cylinder housed in the elongated body,
• a valve closing inlet, and
• a valve opening inlet;
• the fluid inlet, the fluid passage, the fluid cylinder and the fluid outlet are axially arranged with respect to a longitudinal axis;
• and
• the fluid passage defines a fluid chamber comprising an inlet and an outlet configured to enclose the fluid cylinder;
• supplying a liquid to the device for dispensing liquid via the fluid inlet while the fluid outlet is closed by the fluidly actuated valve;
• opening the fluid outlet with the fluidly actuated valve;
• dispensing liquid to the water-soluble pouch;
• and
• closing the fluid outlet with the fluidly actuated valve.
