ABSTRACT:
A fuel injection valve prevents capillary flow by the provision of controlled pressure compensation. In the region of axial extension of the magnet coil, at least one radially extending transverse hole is introduced into the valve housing and this hole is covered by a diaphragm which surrounds the valve housing in the form of a ring. The diaphragm allows pressure compensation without the risk that moisture will penetrate into the interior of the valve and prevents negative capillary flows. The fuel injection valve is suitable, in particular, for use in fuel injection systems of mixture-compressing applied-ignition internal combustion engines.
