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: A pencil type glow plug (10) to be arranged in the combustion chamber of air-compressing internal combustion engines has a tubular plug housing (11) in the longitudinal bore of which a pencil type glow element (16) is sealingly fixed over part of its length. An annular gap (21) is formed in a particular area located at the bottom of or facing the combustion chamber between the longitudinal bore (12) and the glow element (16) for thermally uncoupling the plug housing from the glow element.

摘要: The invention concerns an immobilization device for vehicles having a control apparatus (10, 12, 15) which is isolated only when an authorization check has been carried out. A preliminary release arrangement (19) unconditionally releases the control apparatus (10, 12, 15) on starting for a preliminary release time (Tvor). According to the invention, the preliminary release arrangement (19) restricts the number of possible successive starts with unconditional release to a value which is predetermined in each case. This value is smaller than the value last set if the preceding start was irregular.

摘要: The inventive sheathed element glow plug (10) is characterised by a modified plug-in-caulk connection. According to the invention, the centring windings (18 A) of a glow plug filament can be guided radially or axially into a corresponding U-shaped bead (20) of the connecting bolt (17). Once the glow plug filament has been pre-positioned in the bead, the glow plug filament and the connecting bolt can be caulked. Alternatively, if the geometry of the bead is configured correspondingly, caulking is not necessary. The opening on the periphery of the connecting bolt in the area of the bead (20) makes the inner-lying contour of the bead radially and axially accessible. Organic lubricants can therefore be cleaned away thoroughly and a reliable inspection of the cleaning carried out. This results in a reduced number of premature defects of sheathed element glow plugs caused by organic impurities.

摘要: The invention relates to a sheathed element glow plug for arrangement in the combustion chamber of an air-compression internal combustion engine with a plug shell, a connection member for the glow current and with a tube fastened to said plug shell and closed at the end thereof facing away from the plug shell. A wire filament arrangement embedded in insulating material is positioned in the tube part used as the glow element and projecting from the plug shell. The plug shell (11) comprises two sections and, depending on the desired overall length of the sheathed element glow plug, an intermediate member (23) of selectable length is provided which connects a first part (21) and a second part (22) of the plug shell (11) with each other.

摘要: The invention aims to provide a coupling element (11) for an electrical plug-in connector which is configured in such a way that even under considerable stress, in particular vibration acceleration, said element ensures reliable contact with a mating connector. To this end, the coupling element (11) comprises a two-part contact section (13) consisting of a contact element (18) forming a single piece with a connecting section (12) of the coupling element (11), and at least one support element (19) surrounding at least in part the contact element (18). The contact element (18), which is curved in the shape of a shell and capable of elastic recovery, comprises six contact bodies (28) which form a six-point support, or alternatively a three-line support, for the mating connector. The support element (19), which is also capable of radial elastic recovery, on the basis of its dimensions allows for virtually any form of radial preloading of the contact section (13). The coupling element (11) is used preferably in the automotive industry.
