Abstract
A nozzle for spraying of surfaces has a piston rod with an impact disk, which piston rod is arranged centrally in a feed channel, and which impact disk lies in one end position aligned in the surface to be sprayed and closes off an outlet opening of a flow channel, and lies in a second end position at a distance in front of this outlet opening so that the exiting liquid is deflected into an annular spray fan directed against the surface. The underside of the impact disk, which underside causes the deflection, has a recess on one half of the impact disk periphery, which recess is designed approximately trough-shaped and takes care that half of the annularly discharged spray jet forms a spray fan part, which is directed steeper against the surface than the other half of the spray fan. The spray fan can in this manner be limited to a smaller surface.
