Abstract
A fuel injector, in particular for the direct injection of fuel into a combustion chamber of an internal combustion engine, includes a valve needle that has at its injector end a valve-closure member that works together with a valve-seat surface formed on a valve-seat member, to form a sealing seat. The fuel injector also includes at least one swirl duct; a swirl chamber formed on the valve-seat member, and a plurality of injection openings that open out from the swirl chamber, through which the fuel, provided with a swirl, is simultaneously injected. The at least one swirl duct is formed in the valve-seat member or in a swirl disk adjacent to the valve-seat member.
