Abstract
The invention relates to a fuel injection valve for intermittent fuel injection into the combustion chamber of internal combustion engines. A needle-shaped injection valve member () is arranged in the high-pressure fuel chamber () adjacent to the injection valve seat (), said injection valve member co-operating with the injection valve seat () and defining, in a piston-type manner, the cylinder chamber () which is connected to the high-pressure inlet (). The booster piston () is controlled by means of the control valve () embodied as a flat seat valve, increasing the pressure of the fuel in the high-pressure fuel chamber () for an injection, and thus lifting the injection valve member from the injection valve seat. In this way, the injection is carried out with increased pressure.
