Abstract (en)
[origin: EP2628940A1] The injector has a control valve (1) that controls stroke of nozzle needle (2). A valve chamber (3) formed with low-pressure region (8) is biased against valve seat (6) by valve spring (5), and is lifted by actuator (7). A discharge throttle (9) is projected from end surface (10) of nozzle needle in control chamber (11). The pressure increase in control chamber is effected through feed channel (12) communicated with inlet throttle (13) in closed position of control valve so as to make nozzle needle to close. The inlet throttle is passively controlled with closing element (14).
