ABSTRACT:
In the sequential coating of motor-vehicle bodies using a preprogrammed painter-robot, the paint is switched on and off by an automatically controlled pilot needle-valve (FNV) at predetermined times as a function of the relative positions of the robot and the motor-vehicle body. Return circuits including flow-control valves (DV1, DV2) actuated at predetermined times are provided which match the switching on and off of the pilot needle-valve (FNV) for avoiding unwanted pressure fluctuations.
