摘要： The invention relates to a solenoid valve (10) comprising a magnet assembly (12) and a magnetic top in which a magnetic coil (16) is embedded. The solenoid valve (10) also comprises an armature assembly with an armature bolt (22) and/or armature plate (24) in one or many parts. Said armature plate (24) has, in a radially inner area, a recess (42) that surrounds said area and that defines the height of the residual air gap (52).

摘要： A fuel injection device (20) for a combustion engine comprises a first valve element (36) with a pressure surface (38) that acts in an opening direction. An impinging device (50) acts in a closing direction. A second valve element (34) comprises a hydraulic control surface (58), which acts in the closing direction and which delimits a hydraulic control space (60). A corresponding impinging device acts in an opening direction. In addition, a high-pressure connection (24) is provided. The invention provides that the fuel injection device (20) has an additional valve device (66) that, in a first final position, connects the pressure space (40) only to the low pressure connection (28) and connects the control space (60) only to the high pressure connection (24). In a second final position, the additional valve device (66) connects the pressure space (40) only to the high pressure connection (24) and separates the control space (60) essentially from the high pressure connection (24). In an intermediate position, the pressure space (40) is connected only to the high pressure connection (24), and the control space (60) is simultaneously connected to the high pressure connection (24) and to the low pressure connection (28).

摘要： The invention relates to a device for injecting fuel into the combustion chambers of an internal combustion engine. Said device comprises a pump (2) which supplies a high-pressure collecting chamber (3) with fuel under high pressure. A high pressure supply line leads from said chamber to an injector (5) containing a metering valve (7) which pressurises an injection nozzle (24) by means of fuel. A damper throttle (26) is associated with the metering valve (7) and is connected to part of the high-pressure region.

摘要： The invention relates to a fuel injection valve for internal combustion engines, comprising a housing (1), in which a piston-shaped outer valve needle (10) is arranged in a longitudinally displaceable manner in a bore (3). Said valve needle cooperates with a valve seat (13) configured on the end of the bore (3) located on the combustion chamber side in order to control at least one injection port (7). A control chamber (24) is configured in the housing (1), wherein pressure in the control chamber (24) can be regulated by a valve (33). As a result of the pressure in the control chamber (24), a closing force is exerted at least indirectly upon the outer valve needle (10) in the direction of the valve seat (13). At least one pressure surface (9; 101) is configured in the outer valve needle (10). An inner valve needle (12) is guided in the outer valve needle (10), which controls at least one additional injection port (7) on the valve seat (13) and which is impinged upon by the pressure in the control chamber (24) at least indirectly in the direction of the valve seat (13).

摘要： The invention relates to a fuel injection valve for internal combustion engines, comprising a housing (12; 48), in which a piston-shaped valve member (35; 60) is arranged in a longitudinally displaceable manner in a bore (34; 57). The valve member (35; 60) is surrounded by a pressure chamber (37; 68) configured in the housing (12; 48) on at least part of its length. Said pressure chamber can be filled with fuel at high pressure, wherein the valve member (35; 60) controls the connection of said pressure chamber (37; 68) to at least one injection port (39; 66). The pressure chamber (37; 68) is connected to a damping chamber (46; 80) formed in the housing (12; 48) by at least one throttle (47; 78) arranged in the housing (12; 48) so that pressure oscillations taking place in the damping chamber (46; 60) are rapidly reduced.

摘要： The invention relates to a fuel injection system, comprising a fuel injection valve (15) and a control valve (50). Said control valve (50) has a control valve member (54) which is longitudinally displaceable in a control valve bore (52). A control valve sealing surface (55) is configured on the control valve member and interacts with a control valve seat, hereby controlling the connection between a first pressure chamber (57) and a second pressure chamber (58), said first pressure chamber (57) being connected to a high pressure accumulator chamber (10). A bore (30) is configured in a valve body (25), a piston-shaped valve needle (32) controlling the opening of at least one injection opening (38) in said bore with its combustion-side end, by performing a longitudinal movement under the influence of the pressure from a pressure chamber (31). Said pressure chamber (58) is connected to the second pressure chamber (58) by a delivery channel (28). The first pressure chamber (5) is connected by a throttle (72) to a damping chamber (70) which is otherwise closed, enabling the pressure oscillations that are produced when the control valve (50) closes to be dampened quickly.

摘要： A pencil type glow plug (110) for a self-igniting internal combustion engine and having an integrated combustion chamber pressure sensor is proposed for measuring pressures in the combustion chamber, in particular for an engine control system based on combustion chamber pressure signals. The pencil type glow plug (110) comprises a heating element (112) and a glow plug housing (114) as well as a glow plug axis (124). The glow plug housing (114) includes a zone (116) for receiving the heating element (112), a housing body (120) and at least one flexibility zone (118) arranged between the housing body (120) and the receiving zone (116). At least one force-measuring element (136) is arranged in the glow plug housing (114).

摘要： Disclosed is a fuel injection device comprising a fuel injection valve which is provided with at least one valve element (35) closing at least one injection port. Said valve element is controlled via a servohydraulic valve (131) comprising a movably mounted control piston (123) which separates a control chamber (116) from a pressurized chamber (120) in such a way that the control piston (123) separates a first connection (125) of the pressurized chamber from a second connection (127) of the pressurized chamber in a first position while the first connection is linked to the second connection in a second position according to the filling level of the control chamber (116) such that the valve element (35) can be controlled according to the position of the control piston (123). The inventive fuel injection device also comprises means (150, 154) allowing the fuel pressure that exists in at least one of the partial areas (117, 119) of the control chamber (116) to be used for controlling an additional movable element (37) thereof.
