摘要： A spark plug has a tubular metallic housing, an insulator retained by the housing and an inner conductor arrangement embedded in the insulator and consisting of a connection bolt, an erosion resistance, a contact pin and a platinum central electrode. Four earth electrodes are secured to the housing, are bent towards the central electrode and project with their thickness over the insulator. The contact pin is coated and shortened in such a way that the erosion resistance projects as much as possible into the electrode gap. The platinum central electrode is shaped as a nail whose rear part has a smaller diameter than the front part which projects out of the insulator.

摘要： In the pressure sensor proposed, the pressure is transmitted through a diaphragm (14) and a punch (18) to a piezo-resistive sensor element (19). The sensor element (19) is printed on the substrate of a hybrid circuit (22) and comprises several resistance tracks (38, 39) disposed one above the other in layers, in particular in the form of a pyramid. This makes it particularly simple to transmit the pressure into the sensor in a controlled fashion. In addition, the hybrid circuit is located at one end of the punch stop (23). The compact mounting of the hybrid circuit (22) and piezo-resistive sensor element (19) gives a relatively small, inexpensive design, but a large and relatively error-free sensor signal.

Preferably, breakover diodes (8) connected in cascade are used which only transmit the voltage to the secondary winding (5) of an ignition coil (1) when the ignition voltage is reached at the ignition plug (7) of an internal combustion engine.

摘要： In a process for manufacturing a spark plug for internal combustion engines with at least two metal electrodes separated by a spark gap, at least one of the electrodes has a metallic coating of a highly abrasion-resistant material (noble metal). This material is deposited on the front surface of the metal electrode by laser radiation so as to form an alloy region of special design between the two parts. The special alloy region compensates for the different coefficients of thermal expansion of the electrode material and the metallic coating and effectively prevents depletion of the metallic coating.

摘要： The proposal is for harder-wearing spark plugs for an internal combustion engine. One feature concerns the burn-off resistor (13) of the plug which projects toward the spark path (20) of the plug in order that the current from the charge stored in the ignition capacitor is given off in a limited manner. A further modification relates to the diameter of the inner conductor (11, 16) which is reduced, thus making it possible to reduce the capacitance of the plug. A further modification concerns the electrode head (14) of the inner conductor (11, 16), where it is proposed to coat the electrode head (14) with a noble metal and to use a highly heat-conductive material for the electrode head (14) which acts as a heat buffer.

摘要： In the pressure sensor (11) described, the sensor assembly (19), which is made of at least one piezo-electric material (21) and includes at least one contact disc (22, 23), and the electronic components (33) of an electrical processing circuit are located on the side of a ceramic plate (24) facing towards the sensor diaphragm (14). The other side of the plate (24) abuts a support piece (25). The electronic components (33) and the contact disc (22, 23) are connected to each other by single standard bond wires (34). The pressure sensor (11) is therefore relatively compact and inexpensive to manufacture. In addition, the sensor assembly (19) and the electrical evaluation circuit can be checked in the pre-assembled condition.

摘要： High-voltage switch which can be used in particular as an ignition voltage distributor for applying the ignition voltage to the spark plugs of a combustion engine. The high-voltage switch consists of a cascade connection of opto-electronic semi-conductor elements (5) which are operated or switched by means of incident light radiation. As a result, very high voltages can be switched precisely, and a galvanic separation is ensured between the control circuit and the high-voltage circuit. The control circuit can be operated with a low voltage, so that the unit can be used, in particular in a trouble-free manner, with electronic ignition systems.

摘要： A spark plug (10) which is also suited for igniting lean vaporized fuel/air mixtures. This spark plug (10) surrounds, with its annular metal casing (11), an insulating body (17) which is separated into longitudinal sections and as usual contains, in the hole (20) which passes through it, an attachment bolt (31) and a central electrode (33). A longitudinal section (17/3) of the insulating body (17), surrounded by the metal casing (11), consists of dielectric material and forms, jointly with the metal casing (11) and the attachment bolt (31/2), a capacitor (18) having a capacity of 120 to 500 pF, and essentially 200 to 400 pF. In order to prevent, in the regions of the mating surfaces of the insulating body, flashovers between the attachment bolt (31/2) and the metal casing (11), and to economize costly sintering equipment for connecting the longitudinal sections of the insulating body, annular electrical insulating elements (17/2, 17/4) are arranged between the mating surfaces (24/1, 24,2), which have a rubber-like elasticity at all temperatures of the spark plug (e.g. silicon rubber, epoxy resin).
