Abstract

1522398 Ignition transducers ROBERT BOSCH GmbH 1 Oct 1976 [3 Oct 1975] 40758/76 Heading H2A A transducer for providing an electrical control signal for triggering ignition in an I.C. engine, comprises a coil and a stator and rotor, the stator (11, Fig. 5) and the rotor (Figs. 2 and 3) having pole projections such that on relative rotation a suitable signal (Fig. 6, not shown) is derived in the coil. As shown the member 4 comprises a plate with upstanding pole projections 13, 14, 15, 16 whose length A is considerably greater than the distances B between projections. To provide a desirable signal shape the projection edges 23 slope backwards (Fig. 2) and one end of each projection is bent radially inwards (Fig. 3) the plate having slots 24 to allow this. The member 11 has projections 17, 18, 19, 20, whose length D is small compared with the distances between them. The shapes of rotor and stator may be reversed. The arrangement (Fig. 1, not shown) is mounted with the rotor on a shaft and a permanent magnet is provided. Provision is made for relative displacement dependent on engine pressure.
