More Information
Summary:A fluid metering valve includes a valve-seat surface; a valve closing element that interacts with the valve-seat surface in order to form a sealing seat; an electromagnetic actuator; a valve needle used for operating the valve-closing element; an armature that is guided on the valve needle and is used for opening or closing the sealing seat; at least one stop that is disposed on, and stationary relative to, the valve needle and that restricts a movement of the armature on the valve needle; and at least one damping element that is configured to provide a damping during the opening or closing of the sealing seat, has a volume that is able to be filled with a fluid medium, is configured such that a fluid medium can be exchanged between the volume and an environment of the damping element, and is configured for volume changes of the volume in order to enable the damping.
