Abstract

A nozzle for a spray head includes a nozzle body having a cavity which can be supplied with discharge material via a material feed and in which a swirl-inducing body is arranged which has arranged on it a nozzle insert with a nozzle bore via which the discharge material can be sprayed out. The swirl-inducing body has a disk or plate-shaped base on which an annular web is arranged, with the base being breached by at least one through opening which is arranged radially outside the annular web. The annular web is breached at least one point radially from the outside to the inside by at least one substantially straight or helical groove, and the swirl-inducing body and the nozzle insert are arranged in the nozzle body.
