A nozzle for spraying surfaces is equipped with a piston rod centrally arranged in a feeding duct. The piston rod has an impact plate which is held by a spring in a position aligned with the surface to be sprayed. As a result of liquid pressure, the impact plate arrives in a second end position at a distance from the surface to be sprayed in which. As a result of a ring gap on an input side around the piston rod, the impact plate becomes a deflecting part for the spraying liquid exiting in a ring shape, which, in a circular spraying cone directed at a flat angle with respect to the surface to be sprayed, is then emitted onto the surface to be sprayed.
