Fuel injection valve has supporting ring between elastomeric ring and armature that supports elastomeric ring axially near opening of fuel channel in armature and radially on shoulder

摘要

The fuel injection valve has a valve needle (2) that interacts with a valve seat surface and an armature (17) movably guided on the valve needle and damped by an elastomeric ring (35). The armature contains at least one fuel channel. A supporting ring between the elastomeric ring and the armature supports the elastomeric ring axially near the opening of the fuel channel and radially on a shoulder.
