  • Injection valve with a magnetic ring element
    Patent number: 10982640
    Abstract: An injection valve may include: a valve needle moving from a closed position to an open position; a calibration spring biasing the needle towards the closed position; an armature moving toward the pole piece to take the valve needle towards the open position with respect to the valve needle; and a pole piece. Some valves include a magnetic ring moving between a first position, with a top side spaced apart from the pole piece and an underside in contact with the valve needle, and a second position where the top side is in contact with the pole piece. A second spring is in parallel to the calibration spring.
