摘要： A fuel injection valve for internal combustion engines, having a valve member that is displaceable axially outward counter to a restoring force in a bore of a valve body. On an end toward the combustion chamber, the valve member has a closing head. The closing head protrudes from the bore and forms a valve closing member and on a side toward the valve body has a valve sealing face. The valve closing member cooperates with a valve seat face, disposed on a face end toward the combustion chamber of the valve body. The valve closing member at least one injection opening on the closing head. The injection opening originating at a pressure chamber and outlet opening being covered, in the closing position of the valve member, by the valve body and being uncovered upon an outward-oriented opening stroke. A two-stage hydraulic stroke stop, which limits the opening stroke of the valve member and is embodied as a hydraulic damping chamber with a relief line that can be opened. The relief line can be made to communicate with the damping chamber via at least two recesses on the valve member, the two recesses can be opened in succession during the opening stroke motion of the valve member, and at least one of the recesses can be made to communicate with a low-pressure chamber via a relief conduit that contains a valve.

摘要： A fuel injection valve for internal combustion engines, having a valve member, which is guided axially displaceably in a bore of a valve body. An end toward the combustion chamber and that protrudes from the bore has a valve sealing face with which the valve member cooperates, to control an injection cross section, with a valve seat face on the valve body. A stroke stop face which is stationary relative to the valve body and with which the valve member comes into contact with a bearing face after traversing an outward-oriented maximum opening stroke distance, and the stroke stop face is disposed on an end face of an axially split stroke stop ring which is surrounded by a support ring. A valve spring urges the valve member in the closing direction and is supported stationary on the valve body via a spacer ring and an intermediate member. The support ring surrounding the stroke stop ring is supported stationary relative to the valve body and constantly contacts the spacer ring.

摘要： A fuel injector with a direct needle control for an internal combustion engine, having an actuator, a hydraulic booster, and a nozzle needle guided in a nozzle body and acting on a nozzle needle sealing seat. The hydraulic booster includes a booster piston connected to the actuator and a nozzle needle booster piston connected to the nozzle needle; a booster chamber in the form of an actuator coupler chamber is associated with a pressure surface of the actuator booster piston; and depending on the pressure in the actuator coupler chamber, the nozzle needle is lifted away from the nozzle needle sealing seat, thus initiating an injection. In addition to the actuator booster piston, a control element is provided that is able to execute a stroke motion, is hydraulically coupled to the actuator coupler chamber by means of a first control surface, and is associated with a control chamber by means of a second control surface. The actuator booster piston has a second pressure surface, which, as an additional control surface, is associated with the control chamber.

摘要： A fuel injection system for internal combustion engines, having a high-pressure accumulation chamber, which contains high-pressure fuel, and at least one fuel injection valve, which is connected to the high-pressure accumulation chamber. The fuel injection valve can inject the highly pressurized fuel through injection openings into a combustion chamber of the engine. The fuel injection valve has a control chamber, which is defined by a longitudinally mobile piston and is operationally connected to the fuel injection valve so that the injection cross section of the fuel injection valve is controlled as a function of the hydraulic pressure in the control chamber. A low-pressure accumulation chamber is provided, which can be connected to the control chamber, in which a predetermined fuel pressure is maintained in the low-pressure accumulation chamber that is lower than the pressure in the high-pressure accumulation chamber.
