ABSTRACT:
An injection valve which serves as part of a fuel injection system for internal combustion engines for the purpose of injecting fuel. The injection valve comprises a nozzle body having a valve seat which cooperates with a nozzle needle, which has a needle tip arranged to protrude through an ejection opening. The needle tip and the nozzle needle are embodied as independent parts firmly connected with one another. The ejection opening is embodied in a disc, which is firmly connected with the nozzle body. In order to prevent constriction of the ejection opening during operation as a result of corrosion, the needle tip and disc are manufactured of corrosion-resistant material.
