ABSTRACT:
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 (9) acting on a second contact surface (10), whereby the clamping nut clamps the nozzle body against the housing. The first or second contact surface has a curvature (24) towards the second or first contact surface and the both contact surfaces are in contact in the area of the curvature.
