摘要： System for injecting fuel combustion chambers on internal combustion engines, with an injection nozzle and a downstream glow filament (20, 64, 82) surrounded by a sleeve (30, 66, 84) which contacts the end of the glow filament (20, 64, 82) on the combustion chamber side and is connected to a power supply line (38, 79, 100). The other end of the glow filament (20, 64, 82) is conductively connected to the earth via a contact ring body (24, 68, 88), a thermal protection ring (44, 72, 91) and the nozzle body (10, 60, 80) of the inlet nozzle. This arrangement offers the advantage that there is no need to insulate the contact ring body from the thermal protection ring and the latter can be directly applied to the contact ring body.

摘要： Proposed is a sheathed-element glow plug (10) designed to be fitted in the combustion chamber of air compression type internal combustion engines. As with prior art devices of this kind, the glow plug contains a resistor (17) inside the sheath (13), the resistor (17) being made up of two coils (20, 21) connected in series. While the coil (20) nearest the combustion chamber is a heating coil with substantially constant resistance at all operating temperatures, the resistance-wire coil (21) remote from the combustion chamber, which acts as a control element, has a high coefficient temperature-resistance. The invention calls for the resistance coil (21) acting as the control element to consist of a cobalt/iron alloy whose structure is not destroyed when the alloy is exposed to the temperatures occurring in an internal combustion engine. According to the invention, this alloy is chosen so that it retains a face-centered cubic structure in all operating conditions of the glow plug (10). The iron content of the alloy lies between 6 and 18 % by wt., preferably 12 to 14 % by wt. The coil resistor (17) is embedded, as in prior art devices, in an electrically insulating material (18) which is a good thermal conductor.

摘要： The device comprises an incandescent helix (22, 92) downstream of the injection nozzle and tapering outward in the direction of the combustion chamber. The helix is surrounded by a sleeve (30, 96) which secures the final turn (88, 93) of the incandescent helix (22, 92) on the chamber side and supports a contact ring disc (46, 98) to which the other final turn (86, 94) of the incandescent helix (22, 92) is secured. The final turn (88, 93) on the chamber side is applied against an annular step (90, 107) of the sleeve (30, 96) facing the chamber, which surrounds a through-passage (91, 106) the internal diameter of which is smaller than the external diameter of the final turn (88, 93) on the chamber side, yet larger than the outer diameter of the other turns of the incandescent body (22, 92). In this way, the incandescent helix (22, 92) can still be inserted and connected when the contact ring disc (46, 98) is already attached to the sleeve (30, 96) and forms with the latter a prefabricated unit.

摘要： An injection nozzle fitted with an inductive needle movement probe (28) is to be so constructed that the coil (32) is properly sealed against oil leaks without requiring more space than a design without an oil seal for the coil (32). To this end, the core (36) of the induction coil (30) is extended into a lengthened section (107) of the chamber in the recoil body (25) enclosing the induction coil (30) in which is fitted a ring (56) sealing the coil (32) against the guide slot of the magnet armature (38) in the recoil body (25). In addition, the annular slot between the recoil body (25) and the wall of the drilling in the nozzle holder (10) enclosing it is sealed by a ring (112). The clamping flange (62) linked to the coil core (36) bears directly on the adjacent annular flange (48) of the coil body (34) and the coil (32) makes contact with the connecting wires (40, 42) on the far side of the clamping flange (62). Preferred field of application is in injection nozzles for diesel engines.
摘要翻译：配有感应针运动探针（28）的注射喷嘴应被构造成使得线圈（32）被适当地密封以防止漏油，而不需要比没有用于线圈（32）的油封的设计更多的空间。为此，感应线圈（30）的芯部（36）延伸到包围感应线圈（30）的反冲体（25）中的室的延长部分（107）中，其中安装有环（56））将线圈（32）密封在反冲体（25）中的磁体衔铁（38）的引导槽上。此外，反冲体（25）与包围其的喷嘴保持器（10）中的钻孔壁之间的环形槽由环（112）密封。连接到线圈芯（36）的夹紧凸缘（62）直接承载在线圈体（34）的相邻的环形凸缘（48）上，并且线圈（32）与连接线（40,42）夹紧凸缘（62）的远侧。优选的应用领域是用于柴油发动机的喷嘴。

摘要： A fuel injection nozzle for internal combustion engines has a heater plug (22) mounted downstream of the nozzle opening and integrated in the union nut (12) that tightens the nozzle body (10) against the nozzle holder. The union nut has downstream of the nozzle body (10) a supporting shoulder (18) against which rests a sleeve (30) that surrounds and carries the heater plug (22). The heater plug (22) is composed of a sheathed heating conductor formed as a dimensionally stable spiral (50) and operating as an earth conductor between the contact element (66) and the sleeve (30). The arrangement is thus simpler and easier to assemble. In a preferred embodiment, the connecting end (58a) of the sheathed heating conductor (22a) is conceived as a so-called cold end, thus thermally relieving the adjacent parts, especially the seal of the sheathed heating conductor (22a).
摘要翻译：用于内燃机的燃料喷嘴具有安装在喷嘴开口下游并集成在联接螺母（12）中的加热器塞（22），其将喷嘴体（10）紧固在喷嘴座上。联接螺母在喷嘴主体（10）的下游具有支撑肩部（18），支撑肩部（18）围绕并承载加热器插头（22）并套住套筒（30）。加热器插头（22）由形成为尺寸稳定的螺旋（50）并在接触元件（66）和套管（30）之间作为接地导体操作的护套加热导体构成。因此，这种布置更容易组装。在优选实施例中，护套加热导体（22a）的连接端（58a）被认为是所谓的冷端，从而热释放相邻部件，特别是护套加热导体（22a）的密封。

摘要： The device comprises an incandescent body (22) located downstream of the injection nozzle and designed as a helix tappering outwards in the direction of the combustion chamber. The helix consists of a flat strip (22), whose spiral shape is cut out from a flat metal sheet (74) by means of a laser or for example an acid; it is then stretched in an axial direction. This design simplifies contact of the incandescent body (22) and has the further advantage that the incandescent body (22) can be made from special materials which can only be obtained in the form of flat plate or strip.
