Abstract (en)
[origin: DE102006050812A1] The injector (1) has a control chamber (2) attached to a high pressure side (5), where a movement of a nozzle needle (3) is controlled by pressure of the control chamber. A control valve (6) either closes or opens a connection of the chamber to a low pressure side (7). The control valve has a force balanced control bushing (12), which is movably guided at an end of a valve bolt (9). The bushing closes an annular groove (10) outwards in its closed valve position, and opens the connection of the groove to the low pressure side in its opened valve position, which is moved towards the chamber.
