Abstract
A nozzle for generating a high-pressure jet of a flowable medium, having a nozzle body and a nozzle disk which is embedded in the nozzle body in a recess. The nozzle body includes an axial nozzle bore which leads into at least one of an inlet bore and an outlet bore. The nozzle disk rests under compressive strain on contact surfaces of the recess. Also included is a method for creating a nozzle having a nozzle disk embedded in a nozzle body, the steps comprising: providing a nozzle disk; forming a nozzle body around the nozzle disk in a recess so as to create compressive strain on contact surfaces of the nozzle disk.

A nozzle for generating a high-pressure jet of a flowable medium, having a nozzle body and a nozzle disk which is embedded in the nozzle body in a recess, the nozzle body including an axial, nozzle bore which leads into at least one of an inlet and an outlet bore, the nozzle disk resting under compressive strain on contact surfaces of the recess;
- wherein the nozzle body is braced by an inlet body against a nozzle housing, and wherein common pressure surfaces of the nozzle body and of the inlet body that form a sealing surface are situated outside the nozzle disk;
- and
- wherein on a front side facing the nozzle body, the inlet body has a concentric free cut overlapping the nozzle disk.
A nozzle for generating a high-pressure jet of a flowable medium, having a nozzle body and a nozzle disk which is embedded in the nozzle body in a recess, the nozzle body including an axial, nozzle bore which leads into at least one of an inlet and an outlet bore;
- wherein the nozzle disk rests under compressive strain on contact surfaces of the recess;
- and
- wherein the nozzle body and the embedded nozzle disk have a mirror-symmetrical construction in the longitudinal as well as in the transverse direction.
