<p>A device for charging a primary fluid system, such as an air-conditioning or cooling system, closed and at a first pressure (P1), with a secondary fluid, comprises a dispensing cylinder of the secondary fluid, said cylinder containing the secondary fluid and a propellant fluid having a second pressure (P2) greater than said first pressure. Said cylinder further comprising a filler valve operable to allow/block the exit at least of the secondary fluid from the cylinder. A connection hood is partially superposed over the dispensing cylinder, fitted with connections means suitable for fluidically connecting said filler valve directly to said primary fluid system or to a connection pipe to said system.</p> |
