Fuel injection valve for fitting to internal combustion engines has an injection valve element to control injection openings, a control valve to affect movement in injection valve elements and a valve element for regulating pressure

摘要

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).
