Abstract
Disclosed is a fuel injector for internal combustion engines, in which a cross section (21) of an outlet is unblocked to establish a connection between injection pumps (1) and an injection nozzle (2) at the beginning of the pressure reduction process introducing the end of the injection phase such that the compressed fuel volume can be discharged quickly, thus allowing the pressure to be reduced rapidly.
