The injection valve has a housing, a nozzle body and a clamping nut connected to the housing that contacts the nozzle body with first contact surface () acting on a second contact surface (), whereby the clamping nut clamps the nozzle body against the housing. The first or second contact surface has a curvature () towards the second or first contact surface and the both contact surfaces are in contact in the area of the curvature.

Injection valve comprising an optimized surface geometry between a nozzle body and a retaining nut

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.
