摘要:
The invention relates to a fuel injection valve for internal combustion engines, comprising a valve body (1) and at least one injection opening (11), provided therein. Fuel can be injected through said opening into the combustion chamber of the internal combustion engine in a controlled manner by a valve needle (5) which cooperates with a valve seat (9), provided in the valve body (1). Said valve body (1) is composed of a high-alloy hot-work steel, hardened by a carburizing method.
