Abstract
A fuel injector, in particular for direct injection of fuel into the combustion chamber of an internal combustion engine, includes a valve-closure member which forms a sealing seat together with a valve-seat surface which is formed on a valve-seat member, and several injection orifices, each of which is connected with at least one spiral groove so that an outer edge of the swirl grooves coincides in part with a circumferential edge of the injection orifices. The swirl grooves extend generally perpendicular to a center line of the injection orifice associated with them.
