ABSTRACT:
Fuel injection valves have swirl-generating configurations in order to atomize the fuel as it passes through a narrow flow opening. The fuel injection valve of the invention includes a conduit segment leading to a cylindrical injection conduit. The conduit segment includes a conical widening section and, in the region of a wall of the conical widening section, a highly unstable separation zone is created as fuel passes through it. This zone builds up and collapses again periodically with relatively high frequency so that turbulence created along the wall of the ensuing injection conduit causes the stream surface to break down early as the fuel leaves an injection port; as a result, the stream has fine fuel droplets and nevertheless has a defined stream pattern so that properly aimed injection is made possible. The invention is intended in particular for fuel injection systems for internal combustion engines.
