ABSTRACT:
A piezoelectric injector for fuel-injection systems of internal combustion engines has a piezoactuator guided with spring pretensioning in a valve housing. The actuator presses a sealing piece onto its valve seat through an actuating part, with the actuating part consisting of a pressure pin passing through the piezoactuator and having a head part resting on piezoactuator. The pressure pin and piezoactuator are of the same length and are made of the same ceramic material, in operation the sealing piece is lifted off its valve seat by piezoactuator which is expanded when in the charged state.
