Injector with a magnetic valve for controlling an injection valve

摘要

Injector comprises a magnetic valve (1) for controlling an injection valve (2). The valve has a movable anchor (3) which can be applied to a valve seat (4) in the lower anchor chamber (5). The anchor chamber is in fluid connection with a control pressure chamber (8) of the injection valve via holes (6, 7). Devices are provided for reducing the pressure fluctuations arising in the lower anchor chamber. Preferred Features: One or more sections of the injection such as the return hole (9) and the lower anchor chamber are formed by recesses. A throttle is formed in the return hole in front of the lower anchor chamber.
