Abstract

The disclosure relates to an applicator (RZ), in particular a rotary atomizer, for the application of a coating agent, in particular a two-component paint, comprising a first coating agent connection (SL) for feeding a first coating agent, in particular a basic resin of a two-component paint, a first coating agent strand (L1-L4), which extends in the applicator (RZ) from the first coating agent connection (SL) and carries the first coating agent, and a first valve (SLV1), which is arranged in the first coating agent strand (L1-L4) and controls the flow of the first coating agent, wherein the first valve (SLV1) can be controlled by a first control signal. It is proposed that a first pressure-relief valve (SLV1), which is actuated by its own medium, is arranged in the first coating agent strand (L1-L4) and, to avoid a problem being caused by excessive pressure, opens automatically when the pressure upstream of the first pressure-relief valve (SLV1) exceeds a certain maximum pressure.
