Abstract (en)
[origin: WO2014075988A1] The invention relates to an injector (10) having an injector housing (15), having an actuator (50) and having a nozzle needle (155), wherein the actuator (50) is arranged in an actuator chamber (45) of the injector housing (15), wherein the injector housing (15) comprises a control piston bore (60) in which a control piston (65) is arranged, wherein a leakage pin bore (105) is provided between the actuator chamber (45) and the control piston bore (60), in which leakage pin bore there is arranged a leakage pin (110) which couples the control piston (65) to the actuator (50), wherein the control piston (65) is hydraulically operatively connected for the opening or closing of an outlet opening (195) of the injector housing (15) by means of the nozzle needle (155), wherein a high-pressure line (25) is provided which is designed for transporting a pressurized fuel to the nozzle needle (155), wherein a feed line (225; 260) is provided in the injector housing (15), which feed line connects the leakage pin bore (105) to the high-pressure line (25).
