ABSTRACT:
An electromagnetically actuatable injection valves which tear away the fuel stream emerging from at least one injection port and atomize it as finely as possible. One possibility is to force a high velocity component in the radial direction upon the fuel prior to its leaving the injection valve; this is achieved with swirl generators. The novel injection valve has a valve seat face, which in a swirl segment outside a sealing face, is provided with four swirl conduits, which discharge into an injection conduit and terminal port with a lateral offset relative to a longitudinal valve axis. The novel injection valve is especially suitable as an injection valve for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
