Claim 0:
1. An atomizer adapted for applying a multicomponent paint, comprising:
a) at least one master paint connection for supplying a master paint,
b) at least one hardener connection for supplying a hardener,
c) at least one mixer for mixing the master paint with the hardener to form the multicomponent paint,
d) at least one hardener line leading in the atomizer from the hardener connection to the mixer,
e) at least one master paint line leading in the atomizer from the master paint connection to the mixer,
f) at least one main valve for controlling a delivery of the multicomponent paint, the main valve being arranged downstream of the mixer and controlling a flow of the multicomponent paint to an application element,
g) a first return connection for returning the multicomponent paint from the atomizer to a return line, and
h) a first return line which branches off in the atomizer between the mixer and the main valve and opens into the first return connection, wherein a controllable first return valve being located downstream and a controllable second return valve being located upstream are arranged in series in the first return line.
