Method for the dynamic cleaning of water lines in a vehicle and device for the implementation thereof

In a vehicle (A) having supply ducts for drinking water, a method for dynamic cleaning of a supply duct for drinking water of the vehicle (A), comprising creating a shockwave (0) in the duct to be cleaned, the supply duct having a first end and a second end;

• the method comprising:
• (a) partially filling a volume with a liquid,
• (b) filling the volume that is not occupied by the liquid with gas under pressure,
• (c) releasing the liquid through a bottleneck communicating with the first end of said duct to be cleaned the second end of said duct being open while maintaining the pressure, the liquid being displaced through the bottleneck by the gas under pressure in order to empty the volume of liquid,
• in such a way as:
• to create an accelerated displacement of the liquid from the volume to the supply duct in a first step, create a mixture of gas and liquid in a second step, and create an accelerated displacement of the mixture of gas and of liquid that is created in a second step, and
• to generate a shockwave (0) once the volume is emptied of the liquid, the shockwave propagating through the mixture.
