Connection between an armature and a valve needle of a fuel injection valve

Abstract

A fuel injector (1), in particular for direct injection of fuel into the combustion chamber of an internal combustion engine having fuel mixture compression and spark ignition, includes an armature (20) which cooperates with a solenoid (10), and a valve needle (3) connected to the armature (20), on which valve needle a valve-closure member (4) is provided which together with a valve-seat surface (6) forms a sealing seat. The valve needle (3) passes through the armature (20) and an extension (15) formed on the armature (20) in such a way that a pin (32) may be inserted into a bore (34) in the extension (15) of the armature (20), whose alignment coincides axially and radially with a bore (35) in the valve needle (3), so that an axial pre-lift gap (30) is formed between the armature (20) and the valve needle (3).

Dependencies are inferred from the claim text.
