Abstract
An apparatus for replenishing paint into a paint cartridge ( ), which is capable of putting paint in respiratory circulation while the cartridge is in a waiting state. The apparatus includes a replenishing valve ( ) which is capable of feeding paint to and from a paint chamber ( ) of the paint cartridge ( ) which is set on a replenishing stool ( ), and a respiratory paint circulation valve ( ) which is capable of feeding paint-extruding thinner to and from a thinner chamber ( ) of the cartridge. After switching the replenishing valve ( ) to a drain or discharge side, paint-extruding thinner is supplied from the respiratory paint circulation valve ( ) to push paint out of the paint chamber ( ) of the cartridge ( ). Then, after switching the replenishing valve ( ) to the side of a paint supply source, paint-extruding thinner is discharged by way of the respiratory paint circulation valve ( ) to suck paint into the paint chamber ( ). As a consequence, paint in the cartridge ( ) is put in respiratory circulation to prevent separation and sedimentation of pigment components of the paint.
