摘要:
A fuel injection valve, especially an injection valve for fuel injection systems of internal combustion engines, includes a piezoelectric or magnetostrictive actuator and a valve-closure member, which can be actuated by an actuator via a valve needle and interacts with a valve-seat surface to form a sealing seat. An intermediate piece is connected via a first flexible seal to a support plate; the support plate is connected via a second flexible seal to a driver at the valve needle; and the driver is connected via a third flexible seal to the intermediate piece, thereby creating a sealed hydraulic translation device.
