ABSTRACT:
A fuel injection valve for internal combustion engines, having a valve body and at least one injection opening embodied in it, through which opening, controlled by a valve needle that cooperates with a valve seat embodied in the valve body, fuel can be injected into the combustion chamber of the engine. The valve body comprises a high-alloy hot-work steel, which has been hardened by a case-hardening process.
