The fuel injection device has a high pressure fuel source connected to an injection valve with an injection valve element (28) and a control piston (50) movable in the opening direction when the valve is open and with limiting of the opening movement of th...

The device has a control piston (50) in a control pressure chamber (52) connected to an injection valve element (28) dividing the control pressure chamber into two sub-volumes connected together via a choke point. With a second control valve (70) closed, i...

The fuel injection device has a high pressure fuel pump (10) connected to a fuel injection valve (12) and a first control valve device (62) for controlling an unchoked connection (59) between a pump working chamber (22) and a discharge chamber (24) and a c...

A local pump element (1) for a pump nozzle unit or for a pump pipe nozzle system for compressing fuel is allocated to each injector (2) according to the number of cylinders. The injectors (2) with controlled lift link to a central pressure system (25). The...

The fuel injection device has, for each cylinder of the internal combustion engine, a fuel pump (10) which has a pump piston (18) driven by the internal combustion engine in a stroke movement, which delimits a pump working chamber (22) to which fuel is sup...

The fuel injection device has a fuel pump (10) for each cylinder of the internal combustion engine, which has a pump piston (18) driven by the internal combustion engine in a reciprocating motion, which delimits a pump working chamber (22) that is connecte...

The device has a fuel pump (10) for each cylinder, fuel injection valves (12), and electric control valves (60). A first control valve is located close to the fuel pump, a second control valve (64) is positioned close to the fuel injection valve, and is op...
