초록 ▼

A fuel injection device for internal combustion engines having a high pressure fuel pump driven by the engine. The pump supplies high pressure fuel to a pressure storage chamber, which chamber, for its part, communicates with injection valves that protrude into the combustion chamber of the engine to be supplied. To achieve precise control of the injection times and injection quantities, the injection valve is directly triggered by a magnet valve, to which end the valve needle of the injection valve is embodied as the valve member of the magnet valve. In order to be able to precisely control very small injection quantities and times (for example pre-injection), the adjusting forces of the valve needle are minimized, to which end the valve needle is pressure balanced in every operating state of the injection valve by directing the high fuel pressure after the start of the valve needle opening stroke also onto the face end of the valve needle remote from the valve needle seat.

A fuel injection device for internal combustion engines having a high pressure fuel pump, a pump work chamber (7), which communicates via a closable fuel supply line (17) with a low pressure chamber (15), which is filled with fuel, and via a high pressure fuel line (11), which has a pressure valve (9), with a pressure storage chamber (13), said storage chamber (13) communicates via injection lines (23) with injection valves (25), each of said injection valves protrude into a combustion chamber of the engine to be supplied, each of said injection valves include a valve member in the form of a spring-loaded valve needle (27) which is disposed in a housing and works in conjunction with a valve seat (35), opening and closing motions of the spring-loaded valve needle being electrically controlled, the spring-loaded valve needle (27) of the injection valve (25) is actuated by means of an electromagnet (53) and the spring-loaded valve needle (27) is permanently, mechanically, and rigidly connected with an armature (55) of the electromagnet, the spring-loaded valve needle (27) includes a surface area which act in the opening direction and against which the fuel flows, during the contact of the spring-loaded valve needle with the valve seat (35) and during its opening stroke the surface area is exactly the same area as the surface areas of the spring loaded valve needle (27) against which the fuel flows in the closing direction, and at a start of the opening stroke of the spring-loaded valve needle (27), a fuel communication is opened between the injection line (23) and a chamber defined by a pressure balancing surface on an end of the spring-loaded valve needle (27) remote from the valve seat.
