Solenoid-operated needle valve

摘要

In known electromagnetically actuated valves the valve needle consists, among other things, of a polygon forming link which is connected to the armature. The new valve needle enables a reduction in weight and therefore quicker actuation of the valve. The new valve needle has a link (2) with a circular cross section the armature-side head (7) of which is made by cold forming and is welded with the armature (4). The valve needle is particularly suitable for injection valves in fuel injection installations of spark-ignited internal-combustion engines with mixture compression.
