More Information
Summary:A nozzle comprises a metal dome having an outlet orifice 77 extending therethrough, the nozzle being of metal and having a coating of low-friction plastics such as PTFE, on the outside and inside of the dome and in the edges of the orifice. The exterior end surface of the nozzle is partly spherical and of a larger radius than the semi-spherical portion of the bore. However, the centroid of the internal spherical surface is spaced forwardly of the centroid of the external spherical surface, so that the thickness of the tip decreases toward its axis, that is, toward the apex of the dome. An air cap 13 is provided for blowing air against the exterior of the dome, to clean the outer surface of the dome.
