Abstract (en)
[origin: EP0396223A2] Residual paint is flushed from a paint distribution system (12) by simultaneously injecting a measured volume of atomized solvent and a quantity of compressed air into a manifold (58). Prior to injection, the solvent is first moved into a metering cylinder (44) having an outlet therefrom communicating with the manifold (58). A metering piston (46) is slideable within the metering cylinder (44) for urging the measured volume of solvent into the manifold (58). An air pressure responsive piston (32) is connected to the metering piston (46). At the appropriate times, air pressure is applied to the air piston (32) and also injected into the manifold (58). As the air piston (32) is moved, the connected metering piston (46) forces the measured solvent through an atomizer nozzle (56) and into the manifold (58).
