3/2 Directional-control valve

摘要

The invention relates to a 3/2-port directional-control valve for controlling the injection of fuel in a common rail injection system of an internal combustion engine, with a first switched position in which an injection nozzle is connected to a fuel return and with a second switched position in which the injection nozzle is connected to a high-pressure fuel reservoir. The beginning of the injection takes place in a pressure-controlled manner, whereas the end of the injection takes place in a stroke-controlled manner.
