Abstract

The invention relates to a fuel injector (10) having a solenoid valve (12). A control space (24) which is loaded with a system pressure via a high-pressure feed line (42) can be relieved of pressure via the solenoid valve (12). The control space (24) comprises a high-pressure outlet (52), in which an outlet restrictor (26) is contained and which opens at a valve seat (68) of the solenoid valve (12). A pressure pin (64) is accommodated in the high-pressure outlet (52) in a restrictor plate (44).
