<p>The injector (1) has a linearly movable valve needle (7) e.g. hollow or solid needle, for opening and closing a combustion-chamber side injection aperture (5) of housing (2). A solenoid (11) linearly moves an armature (13). A sleeve is attached to the armature, and made from a solid material than the armature. A stop surface facing away from a combustion chamber is formed on the sleeve. Another stop surface facing the combustion chamber is formed on a valve needle, where the stop surfaces are struck with each other when one of the valve needle and the armature is linearly moved.</p> |
