Abstract (en)
[origin: EP2735725A1] The valve has a control chamber (12) filled with fuel through a supply throttle (27). Closing force is indirectly exerted on a nozzle needle (5) by pressure in the control chamber. The nozzle needle is faced away from a nozzle seat (17). A sleeve (9) is radially bounded in the control chamber. A control piston (14) is arranged in a valve body (10) for defining a valve chamber (16).The valve body is connected with the control piston and the control chamber through an outflow throttle (28) and a control valve (31), which is connected to a low-pressure space (26).
