Bei der Bildung der in jeder bekannten Düseneinrichtung vorliegenden Schraubverbindung entsteht durch Reibung ein Reibmoment, welches versucht, das Düsenteil mitzudrehen. Solches Mitdrehen soll durch ein entsprechend starkes Andrücken des Düsenteils an das Körperteil bei der Bildung der Schraubverbindung verhindert werden. Die Axialkraft, mit welcher das Düsenteil in der fertigen Düseneinrichtung an das Körperteil gedrückt wird, hängt stark vom Reibkoeffizienten in der Schraubverbindung ab, wodurch es im Rahmen einer Serienfertigung solcher Düseneinrichtungen zu starken Schwankungen bei dieser Axialkraft kommen kann.In the formation of the present in any known nozzle device Screw connection creates a frictional torque due to friction, which tries to turn the nozzle part. Such Turning should by a correspondingly strong pressing of the Nozzle part to the body part in the formation of the screw be prevented. The axial force with which the Nozzle part in the finished nozzle device to the body part is strongly dependent on the coefficient of friction in the Screwed off, making it in the context of a series production Such nozzle devices to strong fluctuations in this axial force can come.

Eine besonders bevorzugte Ausgestaltung der Düseneinrichtung ist dadurch ausgezeichnet, dass das Spannteil eine Hülse, welche in eine Ausnehmung in einem Hauptteil eingelegt ist, überragt, und die Teilverbindung zwischen dem Spannteil und der Hülse gebildet ist. Dies hat den besonderen Vorteil, dass es im Hinblick auf die herzustellende Teilverbindung nicht auf die Auswahl sowohl des Werkstoffs für das Körperteil als auch des Werkstoffs für das Düsenteil ankommt. Insbesondere mag es vorkommen, dass der Werkstoff des Körperteils sich nur schlecht zum Schweißen eignet, was die Bildung einer entsprechenden Teilverbindung direkt an dem Körperteil zumindest wesentlich erschweren würde. Hingegen ist es ohne weiteres möglich, für das Düsenteil einen gut schweißbaren Werkstoff zu wählen. Dann kann eine Hülse zum Einsatz kommen, welche in eine entsprechende Ausnehmung des Körperteils eingelegt und beim Verspannen des Düsenteils mit dem Körperteil von dem an das Düsenteil angeformten Spannteil überragt wird.

Especially it may happen that the material of the body part only bad for welding, which is the formation of a corresponding Partial connection directly to the body part at least substantially would complicate. On the other hand, it is easily possible for the nozzle part to a good weldable material choose. Then a sleeve can be used, which in a corresponding recess of the body part is inserted and when bracing the nozzle part with the body part of that the nozzle part molded clamping part is surmounted. The for the connection necessary form-fitting partial connection can then as a welded joint between the clamping part and the Sleeve are performed, for example by laser welding.

eines Fluides, welches im speziellen Fall Dieselkraftstoff
ist. An das Düsenteil 2 angeformt ist ein Spannteil
3 in Form eines Ringes, welches das Körperteil 1 im zusammengebauten
Zustand teilweise überragt. Dabei überragt das
Spannteil 3 eine in dem Körperteil 1 vorgesehene Ausnehmung
6, in welcher eine Hülse 5 angeordnet ist, welche mit dem
Körperteil 1 und dem Spannteil 3 in Formschluss ist. Zur Bildung
der Verbindung 3, 4, 5 werden nach dem Zusammensetzen
der erwähnten Teile zunächst das Körperteil 1 und das Düsenteil
2 mit einer vorbestimmten Kraft aufeinander gepresst.
Anschließend wird die stoffschlüssige Teilverbindung 4 gebildet,
