| 摘要 |
A fuel injector for fuel-injection systems of internal combustion engines has a solenoid coil; a valve needle that is operatively connected to the solenoid coil and acted upon by a restoring spring in a closing direction, in order to actuate a valve-closure member which, together with a valve-seat surface formed at a valve-seat member, forms a sealing seat; and at least two spray-discharge orifices which are formed in the valve-seat member. The spray-discharge orifices are formed in the valve-seat member in such a way that they are shielded from mixture flows circulating in a combustion chamber of the internal combustion engine. |
