Abstract
The invention concerns a fixing device for fixing an injector on a cylinder head. Said injector comprises several axially successive modules pressed against one another by means of a prestressing element. A fixing force for fixing the injector is applied on the prestressing element to counter the influence of opposite forces applied on the injector modules.
Claims20
A method for mounting an injector on a cylinder head, said injector having a plurality of injector modules disposed in sequence in an axial direction, said method comprising:
- bracing the modules against one another by means of a pretensioning element;
- and
- applying a direct or indirect fixing force to the pretensioning element for mounting the injector on the cylinder head, wherein the fixing force is applied via a sleeve component and a ring-shaped element is disposed between the pretensioning element and the sleeve component.
A mounting arrangement for mounting an injector on a cylinder head, said arrangement comprising:
- a pretensioning element for bracing a number of injector modules against one another;
- a sleeve component for applying a force to the pretensioning element in the direction of the cylinder head;
- and
- a ring-shaped element adapted for positioning between the pretensioning element and the sleeve component.
A method for mounting an injector on a cylinder head, said injector having a plurality of injector modules disposed in sequence in an axial direction, said method comprising:
- bracing the modules against one another with a tensioning nut, and
- applying a fixing force to the tensioning nut for mounting the injector on the cylinder head, wherein the fixing force is applied via a sleeve not in contact with the cylinder head.
A mounting arrangement for mounting an injector on a cylinder head, said arrangement comprising:
- a tensioning nut to brace a number of injector modules against one another, said nut having a collar located on one end;
- and
- a sleeve to apply a force to the collar of the nut in the direction of the cylinder head, said sleeve not in contact with the cylinder head.
