Valve for controlling fluids e.g. for fuel injection valves of common-rail or pump-jet injection systems, includes translator for translating stroke movement of piezo-actuator

摘要

A valve for controlling liquids has a piezo-actuator (2) and translator for translating a stroke movement of the piezo-actuator, a resetting element (3) and a valve element (12) for opening/closing an entrance. The translator is formed by a combination of a mechanical translator (9) and a hydraulic translator (4).
