A paint-charging device for charging a cartridge (25) with paint to allow the paint to breathe during standby. The device comprises a charging valve (61) for feeding/discharging paint fed to the paint storage chamber (30) of the cartridge (25) attached to a charging block (52), and a paint breath valve (91) for feeding/discharging push-out thinner to/from a thinner storage chamber (31). The charging valve (61) is switched to the discharge side to feed the push-out thinner from the paint breath valve (91), thereby pushing out the paint in the paint storage chamber (30). Further, the charging valve (61) is switched to the feed side to discharge the push-out thinner from the paint breath valve (91), thereby feeding the pain to the paint storage chamber (30). This allows the paint in the cartridge (25) to perform a breathing action, preventing separation of the pigment in the paint.

La présente invention concerne un chargeur de peinture pour cartouche (25) permettant à la peinture de respirer pendant les temps morts. Le dispositif comporte, d'une part une vanne de chargement (61) permettant l'alimentation ou la décharge de la peinture alimentée vers la chambre de stockage de peinture (30) de la cartouche (25) attachée à un bloc de chargement (52), et d'autre part une vanne de respiration de peinture (91) permettant l'alimentation ou la décharge du diluant propulseur arrivant dans une chambre de stockage de diluant (31) ou en partant. La vanne de chargement (61) est inversée en mode décharge pour l'alimentation du diluant propulseur provenant de la vanne de respiration de peinture (91), ce qui propulse la peinture dans la chambre de stockage de peinture (30). Cela permet à la peinture présente dans la cartouche (25) de réaliser une action de respiration, ce qui empêche la séparation du pigment dans la peinture.
