Abstract (en)
[origin: DE19954288A1] An injection valve element (24) controls an injection opening (26). A control valve (18) affects movement in the injection valve element with a control valve element (62) for regulating pressure in a pressure control area (48). The control valve element moves through adjusting force created by a piezo actuator (80) and thus regulates a pressure control area link with a balancing area (12).
