Abstract:
The present disclosure relates to internal combustion engines. Various embodiments thereof may include a piezo injector for fuel injection. For example, an injector may include: a nozzle unit with a nozzle needle; a piezoelectric actuator unit; and a hydraulic coupler unit coupling the nozzle unit to the actuator unit. The coupler unit includes a coupler piston, a coupler cylinder, and a coupler spring. The coupler piston has a top side facing toward the coupler cylinder and a bottom side. The coupler spring pushes the coupler piston against a face side of the nozzle needle oriented toward the bottom side of the coupler piston and has a contact area with the nozzle needle. The coupler piston includes a passage opening providing a flow connection from the bottom side of the coupler piston to the top side of the coupler piston, arranged within the contact area.

Claim (Index 12):
The piezo injector as claimed in  claim 1 , wherein a lateral pairing clearance between coupler cylinder and coupler piston amounts to at most 10 \u03bcm.
