摘要： A fuel injection valve for high-pressure injection of fuel from a central high-pressure line into combustion chambers of an internal combustion engine, which includes a switching valve with a valve seat and a valve ball; the valve ball in the opened state is lifted from the valve seat by means of a high-pressure jet which is supplied from a throttle bore by a pressure chamber operatively connected to a central high-pressure line. The transition from the throttle bore to the valve seat is embodied as a diffuser.

摘要： A fuel injection system with a fuel injection valve and a control valve, which control valve has a control valve member that can move longitudinally in a control valve bore. The control valve member is provided with a control valve sealing surface, which cooperates with a control valve seat and thereby controls the connection between a first pressure chamber and a second pressure chamber, where the first pressure chamber is connected to a high-pressure accumulation chamber. A bore is embodied in a valve body and contains a piston-shaped valve needle whose end oriented toward the combustion chamber controls the opening of at least one injection opening by virtue of the fact that it executes a longitudinal movement due to the impingement of the pressure in a pressure chamber; the pressure chamber is connected to the second pressure chamber by means of a supply conduit. The first pressure chamber is connected by means of a throttle to a damping chamber that is otherwise closed, as a result of which, pressure oscillations that are produced by the closing of the control valve are rapidly damped.

摘要： A fuel injection valve includes a housing in which a pistonlike valve member is disposed longitudinally displaceably in a bore to cause at least one injection opening to communicate with a pressure chamber embodied in the housing. An inlet conduit discharges into the pressure chamber to fill the pressure chamber with fuel at high pressure. A fuel-filled control chamber in the housing at least indirectly exerts a force acting in the closing direction on the valve member. The control chamber communicates with the inlet conduit and can be made to communicate via a control valve with a leak fuel chamber. A damping chamber communicates with the inlet conduit via a throttle.

摘要： A fuel injection device for internal combustion engines with a high pressure fuel pump that delivers fuel from a low pressure chamber via high pressure lines to at least one injection valve that protrudes into the combustion chamber of the engine to be fed. The device includes a through flow limiting valve that defines a maximum fuel flow quantity in one or a number of high pressure lines and has a valve member, which can move axially and in its closed position, can be brought against a valve seat counter to the force of a restoring spring by fuel flowing toward the injection valve when a maximum fuel flow quantity is exceeded. Wherein the fuel flow through the valve member that is lifted up from its seat can be adjusted in at least one throttle location in the valve member. In order to be able to detect even extremely small leakage quantities, the through flow limiting valve is designed so that in each injection, the valve member executes a stroke motion toward the valve seat but only reaches it when there is a leaky high pressure line, wherein when there are low leakage quantities, the initial position of the valve member moves toward the valve seat during the injection pauses.

摘要： A fuel injection system, having a fuel injection valve and a control valve, which control valve has a control valve member that is longitudinally displaceable in a control valve bore. A control valve sealing face is embodied on the control valve member; it cooperates with a control valve seat and thus controls the communication between a first pressure space and a second pressure space; the first pressure space communicates with a high-pressure collection chamber. In a valve body, a bore is embodied in which a pistonlike valve needle, with its end toward the combustion chamber, controls the opening of at least one injection opening by executing a longitudinal motion in response to the pressure in a pressure chamber; the pressure chamber communicates with the second pressure space via an inlet conduit. The first pressure space communicates via a throttle with a damping chamber, embodied as a blind bore and otherwise closed off, as a result of which pressure fluctuations that occur upon closure of the control valve are rapidly damped.

摘要： A fuel injection valve for internal combustion engines, having a housing (1) in which a pistonlike outer valve needle (10) is disposed longitudinally displaceably in a bore (3) and cooperates with a valve seat (13), embodied on the end of the bore (3) toward the combustion chamber, to control at least one injection opening (7). A control chamber (24) is embodied in the housing (1), the pressure in the control chamber (24) being regulatable by a valve (33), and by the pressure in the control chamber (24) a closing force is exerted at least indirectly on the outer valve needle (10) in the direction of the valve seat (13). At least one pressure face (9; 101) is embodied on the outer valve needle (10) and is acted upon by the pressure in a pressure chamber (5), which is embodied between the outer valve needle (10) and the wall of the bore (3) and extends as far as the valve seat (13), so that an opening force on the outer valve needle (10) results that is oriented counter to the closing force. An inner valve needle (12) is guided in the outer valve needle (10) and controls at least one additional injection opening (7) on the valve seat (13) and is acted upon by the pressure in the control chamber (24) at least indirectly in the direction of the valve seat (13) (FIG. 1).

摘要： A fuel injection apparatus having a high-pressure fuel pump and a fuel injection valve for each cylinder of an internal combustion engine, in which fuel pump has two pump pistons driven by the engine and delimiting a pump working chamber supplied with fuel from a tank. The second pump piston is guided to slide inside the first pump piston. The two pistons can be coupled so that they move as a unit during the delivery stroke or the second can be fixed in a passive position so that only the first executes a delivery stroke. The fuel injection valve a second injection valve element which is guided to slide inside a first injection valve element can be acted on by the pressure prevailing in a control pressure chamber which has a connection to the pump working chamber controlled by the second pump piston wherein the control pressure chamber is disconnected from the pump working chamber when the second pump piston is disposed in its passive position.
