Abstract
A fuel injection valve for internal combustion engines, with a high pressure connection, which feeds laterally into a valve retaining body inserted into the engine housing, which connection is constituted by a pressure pipe connector which is inserted into a through bore in the housing. The pressure pipe connector is connected to a pressure line by means of a male pipe fitting and is axially braced by this fitting against a seat on the circumference face of the valve retaining body. In order to limit the clamping forces of the high pressure connection introduced radially onto the valve retaining body, a region is provided between the force introduction onto the pressure pipe connector and its contact with the valve retaining body, which region plastically deforms from a particular clamping force onward.
