ABSTRACT:
Fuel injector, in particular, a fuel injector for the direct injection of fuel into a combustion chamber of an internal combustion engine is described having an actuator for actuating a valve needle, the valve needle having on an injection-side end a valve-closure member which forms a sealing seat together with a valve-seat surface, which is formed on a valve-seat member. Fuel channels are arranged in a valve needle guide, connected to the valve-seat member or designed as a single piece with it, in several rows circumferentially in the valve needle guide, at least one row of fuel channels being arranged, in the resting state of the fuel injector, above a guide line of the valve-closure member.
