摘要： In the case of an injector of a modular common-rail fuel injection system having a high-pressure accumulator (6) which is integrated into the injector body, the injector (1) comprises an injection nozzle (3) with a nozzle needle (15) which is guided axially displaceably therein and is surrounded by a nozzle chamber (19), a high-pressure bore (8) which connects the high-pressure accumulator (6) to the nozzle chamber (19), a resonator bore (20) which is connected in parallel to the high-pressure bore (8), is connected to the injection nozzle (3) and opens into the high-pressure accumulator (6) via a resonator throttle (21), and a holding body (5) which is screwed on the end side to the component, in particular common rail (25), which forms the high-pressure accumulator (6), and through which holding body (5) the high-pressure bore (8) and the resonator bore (20) run. An end section (32), facing the high-pressure accumulator (6), of the high-pressure bore (8) and an end section (33), facing the high-pressure accumulator (6) and having the resonator throttle (21), of the resonator bore (20) are configured in a separate component (23) which is inserted between the holding body (5) and the common rail (25) and is fixed by the screw connection of holding body (5) and common rail (25).

摘要： The invention relates to a high-pressure seal (1), especially for fuel injection valves, for sealing a borehole (4) provided in a body (3). The high-pressure seal (1) comprises a sleeve (9) provided with a profiled element at least in sections on an outer side. The high-pressure seal (1) comprises a sealing bolt (11) having at least one blind hole (19) and a compression element (12). The sleeve (9) is inserted into the borehole (4) from a first side (6), the sealing bolt (11) being introduced into the sleeve (9) from a second side (7) opposite the first side (6). An outer diameter (c) of the compression element (12) is larger than an inner diameter (b) of the blind hole (19) of the sealing bolt (11). The compression element (12) is pressed into the blind hole (19) of the sealing bolt (11) such that at least one form closure is formed between the profiled element (14) of the sleeve (9) and the body (3) in the region of the borehole (4). A collar (18) of the sealing bolt (11) is pressed at least indirectly against the body (3) on the second side (7).

摘要： The invention relates to a device for adjusting the stroke of the armature (3) of a solenoid valve by activating the permanent magnet (11) of a solenoid valve (1). The inventive device comprises a thrust sleeve (4) arranged in an axial guide (10) in such a way that it is axially adjustable with respect to the main body (2) of the solenoid valve (1) and comprises a thrust which makes it possible to limit the axial stroke of the armature. Said device also comprises a movable adjusting element (5) consisting of two threaded sections (6, 7) which have different threads (P) and an identical thread direction and make it possible to adjust the position of the thrust sleeve (4). The first threaded section is connected to the corresponding threaded section (8) of the thrust sleeve (4), the second threaded section (7) is connected to the corresponding threaded section (9) of the main body (2). The inventive solenoid valve (1) which is provided with said device and is used, in particular for a fuel injector is also disclosed.

摘要： A fuel injector is provided which has an improved structure capable of adjusting fuel jet characteristics such as the quantity of fuel to be injected to an engine and a fuel injection time lag after the fuel injector is assembled. The fuel injector includes an air gap (H) adjusting screw (31) and a spring (38) pressure adjusting screw (37). The air gap adjusting screw (31) serves to change an air gap (H) between a stator (34) and an armature (32) of a solenoid valve to adjust the quantity of fuel to a target one. The spring pressure adjusting screw serves to change a spring pressure urging a valve in a spray hole-closing direction to regulate a spray hole open duration, thereby adjusting the fuel injection time lag or the quantity of fuel.

摘要： The invention relates to a high-pressure fuel device comprising a housing (1) with a first high-pressure body (3) and a second high-pressure body (5), which lie adjacent to one another on a bearing surface (30). A high-pressure chamber (23), which is configured in the housing (1) and contains a high pressure of fuel, at least temporarily, penetrates the bearing surface (30). A partition part (7) with a longitudinal axis (15), surrounds the housing (1), at least in the area of the bearing surface (30), in such a way that an oil leakage chamber (32), which is sealed off from the exterior, is formed between the partition part (7) and the housing (1).
