Abstract (en)

[origin: DE10159749A1] A fuel injection valve (1) for directly injecting fuel into the combustion chamber of an internal combustion engine comprises a piezoelectric or magnetostrictive actuator (6) and a hydraulic coupler (2). The coupler (2) has a master piston (3) and a slave piston (8), which are connected to a pressure space (14), and the pressure space (14) is filled with a hydraulic fluid. The pressure space (14) is sealed from an actuator space (21) by a first seal (12) and from a valve interior space (17) by a second seal (13).

[origin: DE10159749A1] The fuel injection valve (1) for an internal combustion engine comprises a pressure space (14) which is filled with a hydraulic fluid and, by means of sealing units (12, 13), is separated respectively from the actuator and fuel spaces (21, 17).
