Valve, in particular a suction valve, in a high-pressure pump of a fuel injection system

A valve including a magnet actuator (22) which has a magnet coil (6), a magnet armature (10) that moves in a stroke-like manner, and a pole core (20), wherein the magnet armature (10) and the pole core (20) together limit a working air gap (28), and the magnet armature (10) can at least indirectly c...

More Information
Summary:A valve including a magnet actuator (22) which has a magnet coil (6), a magnet armature (10) that moves in a stroke-like manner, and a pole core (20), wherein the magnet armature (10) and the pole core (20) together limit a working air gap (28), and the magnet armature (10) can at least indirectly contact the pole core (20), wherein the valve also has a valve element (14) which can be moved between an open position and a closed position, and which is at least indirectly in mechanical contact with the magnet armature (10). A separate magnet armature insert (8) arranged in the magnet armature (10) and/or a separate pole core insert (24) arranged in the pole core (20) is provided in the contact area of the magnet armature (10) on the pole core (20), in order to achieve a separation of the mechanical and magnetic forces.
