A fuel injector comprising an outer valve needle (14) and an inner valve needle (30), the inner valve needle (30) being slidable within a bore (28) formed in the outer valve needle (14). The inner and outer valve needles (14, 30) are exposed to fuel pressu...

A fuel injector comprising a nozzle body (10; 10a 10b) provided with first and second outlet openings (15, 21) for fuel and a valve needle (12) slidable within a valve needle bore (11; 65a) defined in the nozzle body (10; 10a, 10b). The valve needle bore (...

The fuel injection valve (12) has a second, sliding injection valve component (128) inside the hollow construction of the first injection valve component (28). This controls a second injection opening (132). It is subjected to pressure ruling in the pressu...

The fuel injection valve has an inner control chamber (42) whose pressure exerts a closing force on an inner valve needle (12) and an outer control chamber (55) whose pressure exerts a closing force on an outer valve needle (10). Both control chambers are ...

The fuel injection device (10) includes a casing (11) with a closed injection end (22) and with a recess (18, 20) running along it. There are two axial outlets at the injection end. The device has its compression cavities (e.g. 34) connected by a common co...
