Beschreibung
Zusammenfassung:	A fuel injector, in particular an injector for fuel injection systems in internal combustion engines, has a piezoelectric or magnetostrictive actuator, a valve closing body which can be operated by the actuator by way of a valve needle and which cooperates with a valve seat face to form a sealing seat, and having a hydraulic lifting device including two lifting cylinders that can move in opposite directions. The lifting device is a subassembly hermetically sealed off from a valve interior and has a housing having at least one section which is flexible in the axial direction.
