Valve for metering a fluid, especially a fuel injector

A fuel injector, which is a valve for metering a fluid, for directly injecting fuel into a combustion chamber, for a fuel injection system of an internal combustion engines, comprising:

• an excitable actuator to actuate a valve-closing member which, together with a valve-seat face formed on a valve-seat member, forms a sealing seat, and including at least one injection opening which is formed downstream of the valve-seat face, the at least one injection opening being placed in a center area of the valve-seat member projecting outwardly in a dome-like manner in the injection direction;
• wherein the dome-like center area of the valve-seat member has a curved outer contour, the curvature in a radially inner section having a larger radius than the radius of the curvature in a radially outer section of the dome, which ends radially outside of the mouth areas of all injection openings, in a recessed depression, that is followed radially outwardly by an again axially projecting edge area of the valve-seat member.
