Abstract (en)
The arrangement has a piezoelectric actuator (17) provided with a movable actuating unit. A hydraulic coupling area (18) is limited by a control surface of a valve piston (6) and a control surface of the actuating unit in opening direction of the piston. A piston rear area (24) is connected to a high pressure-fuel supply (4) and limited by another control surface of the piston, where a closing force acting on the piston is larger than an opening force.
