摘要： A spark plug for internal combustion engines ensures the formation of two spark paths. These two spark paths are a pure air spark which jumps over from electrode to electrode, and a creepage spark which emerges from the central electrode, creeps along the insulator and then jumps over at the point at the smallest distance between the insulator and the earth electrode. The spark plug includes a cylindrical metal tube which forms a housing and in which the central electrode is arranged, surrounded centrally by an insulator. The earth electrodes mounted on the metal tube are partially bent so that an obtuse bending angle of the bent-over part with respect to the part of the earth electrode which extends in the direction of the rotationally symmetrical longitudinal axis is produced.

摘要： A spark plug for an internal combustion engine includes a middle electrode which has an electrode base body (5) with an end face (51) oriented toward the combustion chamber, to which end face a precious metal platelet (8) is attached. An end section (15) of the electrode base body oriented toward the combustion chamber is formed in the shape of a truncated cone. The precious metal platelet (8) is likewise formed in the shape of a truncated cone and the diameter of the end face (52) of the electrode base body oriented toward the combustion chamber corresponds to the diameter of the end face (84) of the precious metal platelet oriented away from the combustion chamber. A method for producing middle electrodes for a spark plug of an internal combustion engine is also proposed.

摘要： The connection conductor leading from the connection end of a sensor element towards the end of the sensor remote from the gas to be measured is a metallic connection part (17) that is rigid against torsion and passes through the aperture (16) of the closure shell (14) where it is sealed by a bead-like element (41) having a tubular extension (48), beyond which the connection conductor has an axial internal connection surface for a cable (19). A sleeve (51) of yielding material (51) covers the adjoining ends of the cable and of the connecting conductor and an overlay shell (52) compresses the sleeve to make a tight seal, both around the cable and against the tubular end of the bead (41). The overlay shell snaps on to the tubular extension of the bead by interlocking annular sawtooth ridges.
