Abstract
A fuel injection valve for an internal combustion engine may include an injector body having a receiving hole for an injector needle. The receiving hole may be implemented as a blind hole and may form an injector ring chamber in the injector shaft and a cone-shaped valve seat at the base thereof, and a blind injector hole at the tip of the valve seat cone, from which at least one injector hole extends. The injector needle may include an at least partially cone-shaped needle tip and may seal off the blind injector hole, and thus the at least one injector hole, from the injector ring chamber. The needle tip may include a needle pilot adapted in contour and extent to the blind injector hole in the valve seat, the pilot protruding into the blind injector hole and thus reducing a compression volume formed between the valve seat and injector hole.
