Abstract (en)
[origin: WO2005121543A1] The invention relates to a fuel injector (1) comprising a piezoactuator (8) which operates an injection valve member (9). Said piezoactuator acts upon the injection valve member (9) which is impinged upon by a spring element (15) in the closing position. The fuel injector (1) comprises a hydraulic coupling chamber (13) which hydraulically connects a transmission piston (10) and the injection valve member (9). A sleeve-shaped body (17) supports the injection valve member (9) which co-operates with an edge (18) forming an intermediate lifting stop for the injection valve member (9).
