Abstract
An electromagnetically actuable rate control valve for controlling a delivery rate of a high-pressure pump includes an electromagnet, a valve element, an armature shaft, and at least one strength element. The valve element is movable in an axial direction and is configured to open and to close the electromagnetically actuable rate control valve. The armature shaft transmits a force. The force is produced by the electromagnet and acts on the valve element in the axial direction. The at least one strength element is configured to raise at least the strength of the armature shaft. The armature shaft includes a needle region adjacent to the valve element and an armature region remote from the valve element. The needle region and the armature region are integral with each other.
