Abstract:
An electromagnetically actuated valve having a longitudinal valve axis, comprising:a core;a solenoid coil at least partially surrounding the core;a stationary valve seat; andan axially movable valve needle including a closing-member support and a spherical valve-closure member, the spherical valve-closure member being fixedly joined to the closing-member support and cooperating with the stationary valve seat, the closing-member support having an inner longitudinal bore extending to a surface of the spherical valve-closure member, and a downstream end area having an external diameter which is greater than a diameter of the spherical valve-closure member, the closing-member support surrounding the spherical valve-closure member with the downstream end area to form at least one channel extending along a surface of the spherical valve-closure member, the at least one channel including an axially elongated portion and being connected to the inner longitudinal bore, the at least one channel extending to an end portion of the downstream end area and at least to a sphere equator of the spherical valve-closure member in a downstream direction.
