Abstract

An injection valve for the injection of fuel during a low pressure phase into a space subjected to pressure fluctuations, which includes an injection nozzle equipped with a nozzle seat that is provided with at least one nozzle aperture; the nozzle aperture is adapted to be covered off by a nozzle needle which is adapted to be lifted and is limited in its lifting movement by an abutment at least in its opening direction; the nozzle seat is thereby movable in the lifting direction of the nozzle needle.
