Abstract

The nozzle has a housing (12) with a discharge chamber having a slot-like designed discharge opening (14) and an inlet opening that is formed by a circular diaphragm (16). A basket- like inserted part (18) is arranged downstream to the diaphragm by the discharge opening. An abrupt cross sectional extension is provided downstream of the diaphragm and upstream of the inserted part, where a ratio between the fluid pressure downstream to the diaphragm and the fluid pressure in the chamber upstream of the part amounts between 100:1 and 50:1 in the operation of the nozzle.
