PIEZOELECTRIC ACTUATOR MODULE WITH A SHEATHED PIEZOELECTRIC ACTUATOR

Anordnung mit einem Piezoaktor und ein Verfahren zu dessen Herstellung

Injector for fuel supply to internal combustion engine, especially in motor vehicle, has piezoactuator with foot on end remote from nozzle needle with sealing profile facing needle that contacts seal seat on injector body

Piezoactuator e.g. for fuel injector of IC engine, has piezoelement clamped between head and foot parts, and casing attached securely to foot part in sealed manner
