摘要： A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle situated in a nozzle body, the valve needle being actuable by an actuator and acted upon by a restoring spring in such a manner that a valve-closure member which is in operative connection to the valve needle and faces the combustion chamber is kept in sealing contact with a valve-seat surface in the non-actuated state of the actuator. A first jet-opening angle α1 is assigned to a first lift state of the valve needle and a second jet-opening angle α2 to a second lift state of the valve needle.

摘要： A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine encompasses a piezoelectric or magnetostrictive actuator, a valve needle actuable by the actuator, the valve needle cooperating with a valve-closure member to form a sealing seat together with a valve-seat member, and a restoring spring by which the valve needle is acted on in a closing direction. The valve needle is pressure-equalized in that the force exerted by the fuel pressure on the valve needle in the opening direction is approximately equal to the force exerted by the fuel pressure on the valve needle in the closing direction.

摘要： A fuel injector for fuel injection system of an internal combustion engine includes a solenoid coil, an armature acted upon in a closing direction by a return spring, and a valve-closure member frictionally connected to the armature. The valve-closure member, together with a valve-seat surface, forms a sealing seat, the armature striking with an armature stop face against a magnetic-pole surface of a magnet body. The armature stop face includes a first annular, inner edge zone that adjoins an inner edge and is inclined inwardly with respect to a plane perpendicular to longitudinal axis of the armature, and has a second annular, outside edge zone that adjoins an outer edge and is inclined outwardly with respect to a plane perpendicular to the longitudinal axis of the armature.
