摘要： A fuel injector for injecting fuel into an internal combustion engine has an at least two-stage pressure boosting or a variable pressure boosting and an actuator able to actuate an injection valve member. A prestroke element travels a prestroke distance hv during the opening movement of the injection valve member until it reaches a changeover point of the pressure boosting. The injection valve member or a second piston is associated with a prestressing spring element, which can be a disk spring, a tubular spring, a helical spring, or a spring element integrated into the second piston. During the passage through the prestroke distance hv, the prestressing spring element continuously builds up the force required to switch the pressure boosting from a first opening pressure po,1 to a second opening pressure Po,2.

The valve member has a first opening surface, which defines a first opening pressure chamber in the opening direction of the valve member, wherein the first opening pressure chamber is connected to a high-pressure fuel source and the pressure in the first opening pressure chamber produces a first opening force against the first opening surface. The valve member also has a first closing surface, which defines a first closing pressure chamber in the closing direction of the valve member, wherein the first closing pressure chamber is connected to the high-pressure fuel source and the pressure in the first closing pressure chamber produces a first closing force against the first closing surface.

摘要： A fuel injection valve for an internal combustion engines is proposed, in which the control of the fuel injection valve member is controlled through the control of the pressure of a control chamber (25). This chamber is either relieved by means of a control valve (31) or is subjected to a high pressure, which brings the fuel injection valve member into the closed position. At the same time as the relief of the control chamber, a valve member (33) of a safety valve (32) that controls the fuel supply to the fuel injection valve is opened so that upon opening of the fuel injection valve, high-pressure fuel simultaneously also can travel by way of a pressure line (12) from a high-pressure fuel reservoir (14) to the injection openings (8) of the fuel injection valve (1). After the end of the injection, the valve member (33) is closed again, together with the closing of the fuel injection valve member (5). Consequently, in the event of a malfunction, unwanted fuel is prevented from reaching injection for a long period of time and consequently possibly destroying the associated engine due to overdosing.
