Abstract (en)
[origin: WO2014127794A1] Disclosed is a fuel injector (10) for a fuel injection device, wherein the injector (10) has a control chamber (28), which can be selectively relieved of pressure by means of a pilot valve (54) of the injector (10) in order to control the nozzle needle stroke of an axially displaceable nozzle needle (12) of the injector (10), wherein the fuel injector (10) has at least one nozzle (20) on a first end (12a) of the nozzle needle (12) and has the control chamber (28) on a second end (12b) of the nozzle needle (12), wherein the control chamber (28) is sub-divided by a throttle plate (38) accommodated therein into a first chamber (40), which is further away from the nozzle, and a second chamber (42), which is closer to the nozzle, said chambers communicating with each other via the throttle plate (38), wherein a first resilient element (46) and a second resilient element (48) are each accommodated in a pre-stressed manner against the throttle plate (38) in the first chamber (40) and in the second chamber (42) respectively, which resilient elements (46, 48) axially displaceably bear the throttle plate (38), and wherein a high-pressure inflow line (50) into the control chamber (28) and a relief outflow line (52) out of the control chamber (28) lead into and out of the first chamber (40) respectively.
