Abstract
942,973. Sparking plugs. COMPAGNIE GENERALE D'ELECTRICITE. May 17, 1962 [May 20, 1961], No. 19084/62. Heading FIB. In an interference suppressor sparking plug having two resistors 8, 9, connected in series and forming with a capacitance formed by coatings 6, 7, on the insulator 1 a suppressor network, an inductive element 11 is connected in series with the capacitance. The suppressor circuit is shown in Fig. 1b. The resistors, 8, 9, are connected in series by a wire 10 and are urged apart against the terminal 3 and electrode connector by a coil spring 11 which is electricallyconnected to the resistor 9 but insulated from the resistor 8 by a washer 13. The spring is arranged so that one of its coils 14 contacts the coating 6, whereby the part of the spring between resistor 9 and the coil 14 forms an induction coil in series with the capacitance 6, 7, the outer coating 7 being earthed by the plug connector. In Fig. 2a the induction coil is formed by part 15 of the outer coating 7 which is formed as a helical coil.
