Abstract
A HVLP spray unit with an electric fan comprising a needle valve for metering the paint which is fed to an air cap, the needle valve comprising a valve body with an elongate interior space, a valve needle, a compression spring and a seal, the interior space between the seal and a nozzle opening of the valve body being configured as a paint chamber, into which a feed channel for the paint opens and which is flowed through by the paint during spray operation of the HVLP spray unit. Here, the interior space of the valve body is tapered between the feed channel and the seal in such a way that a needle guide is formed, and that, in a manner which lies opposite the paint chamber, the seal is arranged so as to bear against the needle guide.
