Abstract: A paint dosage device is particularly adapted to be mounted in close proximity to a spray gun (P) in a program controlled spray painting installation for dosed paint supply to the spray gun. The device comprises at least two dosage cylinders (SA, SB), each having a regulating piston (PA, PB) connected to regulation means (RA, MA; RB, MB) for setting the paint filling amount of the associated cylinder by controlled adjustment of the departure position of the regulating piston in the cylinder. The regulation means is also adapted for setting the dosage rate of the cylinder when supplying paint to the spray gun, by program controlling the displacement velocity of the regulating piston in the cylinder. A valve assembly (V1, V2, V3, V4) is arranged for connecting the cylinders (SA, SB) alternately to the spray gun (P) and putting the cylinder disconnected from the gun in connection with means for cleansing and paint filling. This paint dosage device is particularly suitable for application in the case the spray gun is provided with high tension electrode (E) for electrostatically charged atomizing of supplied electrically conductive paint. Each regulating piston (PA, PB) of the cylinders is then connected with the regulation means by means of an electrically insulating motion-transferring connection (IA, IB) and each valve (V1, V2, V3, V4) of the valve assembly is made electrically insulating.
