Abstract
A fuel injector for fuel-injection systems of internal combustion engines includes a solenoid coil, a valve needle that is in operative connection with the solenoid coil and acted upon by a restoring spring in a closing direction in order to actuate a valve-closure member which forms a sealing seat together with a valve-seat surface formed at a valve-seat member, and at least two spray-discharge orifices, which are formed in the valve-seat member. In a discharge region, the spray-discharge orifices are in connection with capillaries formed in the end face of the valve-seat member.
