Abstract (en)
[origin: WO2012010368A1] The invention proposes a fuel injector having a hydraulic coupler unit (10) which has a coupler body (12), a coupler piston (13) and a valve piston (14). The valve piston (14) has a sleeve-like guide section (23), which is guided on a guide piston (21) formed by the coupler body (12) and arranged in the center of the coupler unit (10). The implementation of the coupler unit (10) requires that either the coupler body (12) or the valve piston (14) be designed from at least two individual components.
