Patent ID: 7354027

Claim:
A magnet valve for actuating a fuel injector, comprising a magnet core ( 2 ), a magnet coil ( 3 ) received within an annular recess ( 24 ) of the magnet core ( 2 ), a closing spring ( 9 ) disposed within a bore ( 6 ) of the magnet core ( 2 ), the closing spring biasing an armature plate ( 11 ) of a magnet armature ( 10 ) to close the magnet valve, fuel outlet openings ( 18 , 35 ) being formed between the armature plate ( 11 ) and the magnet core ( 2 ), an armature bounce reducing damping face ( 20 ) applied adjacent to the magnetic coil within the annular recess ( 24 ) of the magnet core ( 2 ), and a hydraulic damping chamber ( 31 ) defined by one end face ( 12 ) of the magnet armature ( 10 ) on the armature plate ( 11 ) and by the armature bounce reducing damping face ( 20 ), said fuel outlet openings ( 18 , 35 ) respectively discharging fuel into and out of said hydraulic damping chamber, and wherein the damping face ( 20 ) is comprised of a non-magnetic material ( 16 ).
