发明名称 Fuel injection valve for internal combustion engines
摘要 A fuel injection valve for internal combustion engines, having an associated valve body, wherein the valve body is inserted into the receiving bore of the housing of an internal combustion engine and-by means of a clamping element, which is screwed into an internal thread embodied at the end of the receiving bore remote from the combustion chamber, and a support element disposed in an annular groove-is clamped with an annular shoulder embodied on the valve body against a contact surface embodied in the bore. The inner circumference surface of the clamping element and the outer circumference of the support element are conically embodied so that the axial movement of the clamping element when it is screwed in, exerts a radial force on the support element as a result of which it is pressed with its cylindrical inner circumference surface into the annular groove and as a result, a high axial force can be transmitted to the valve body without high surface pressures occurring as a result.
