Abstract

The invention sets forth a fuel injection valve for internal combustion engines, having a valve body and an expansion sleeve that cooperates with the valve body. A pressure chamber is defined between the expansion sleeve and the valve body into which a high-pressure conduit discharges which can be made to communicate with an injection cross section into the combustion chamber of the engine via an opening cross section, openable at high pressure, between the expansion sleeve and the valve body. The cup-shaped expansion sleeve is slipped onto the circumferential jacket face of the valve body and braced axially against the valve body; a portion of the expansion sleeve is embodied as a fastening element on the valve body.
