    摘要: A fuel injection device for internal combustion engines which supplies fuel from a high-pressure fuel source to a fuel injection valve, controlled by means of a control device. The fuel injection valve has an injection valve member which is acted on with the supplied high fuel pressure by means of a pressure shoulder and can consequently be opened in order to execute the injection. The fuel is supplied via a pressure line whose flow is controlled by a control valve whose control valve member is moved between first and second valve seats in a valve chamber and thereby controls the connection between the high-pressure fuel source and the fuel injection valve via the valve chamber for a preinjection and a main injection.

    摘要: The invention relates to a fuel injection valve that has a valve member which can control a fuel outlet opening. 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.

    摘要: A fuel injection valve for internal combustion engines, with a valve member which is guided axially displaceably in a bore of a valve body and which has, at its end on the combustion space side, a conical valve sealing face, the valve sealing face cooperates with a conical valve seat face at that end of the bore located on the combustion space side, a blind hole or a conical region adjoining said valve seat face on the combustion space side, with a pressure space opening onto the valve seat and located between the valve member shank and the wall of the bore, and with at least one injection duct leading off from an inner wall of the injection valve, said inner wall being located downstream of the valve seat. For forming the injection jet, the entry regions of the injection duct are rounded, an upper entry region which faces the pressure space having a large radius (RA) and a lower entry region which faces away from the pressure space having a smaller radius (RB). Thus, the size of the radius (RA) is 0.75 to 1.5 times and that of the radius (RB) 0.2 to 1.0 times the diameter (D) of the injection duct.
