Definitions

  • a starter motor control circuit contains a relay having two windings associated in opposed relationship, the first winding being energized through the medium of the ignition key switch and the second winding from the alternator through a special group of rectifying diodes of which the number is proportional to that of the phases of said alternator and the capacity consistent with the current drawn by the winding of the starter relay supplied therethrough.
  • Patented 4 May 18, 1971 3,578,981
  • the present invention relates to control systems of internal combustion engine starter motors.
  • Devices operating on current produced by the dynamo are advantageous in that they are particularly simple in design for it is only necessary to connect the starter motor or preferably its control relay or solenoid in opposition to the voltage derived from the dynamo.
  • This control system comprising, branched OR the energizing circuit of an ignition distributor, a relay controlling the starter switch in series with a front contact actuated by a selector lever of the change-speed transmission mechanism, is characterized in that said relay comprises a pair of associated and oppositely connected windings of which one is adapted to be energized through the ignition key switch and the other from the alternator through a special group of rectifying diodes the number of which is proportional to the number of phases of the alternator, the capacity of said diodes corresponding on the other hand to the current absorbed by the starter relay winding energized therewith.
  • This device comprises in an electrical ignition circuit connected to the inserted terminal of a storage battery an ignition key switch CC connected in turn to the ignition distributor AL, the circuit being completed to the ground. Branched off this circuit between the ignition key switch and the distributor is the input terminal E, of a first winding R, of a starter motor control relay R. Another winding R of this relay, wound in opposition to said first winding R, has its input terminal E connected to a group of three star-connected diodes D each connected in turn to a separate terminal of a three-phase alternator A supplying charging current to the storage battery through a diode bridge rectifier RD having its negative terminal grounded. The output terminal S common to both winding R, and R of relay R is connected to a front contact CF responsive to the selector control lever L of the change-speed transmission mechanism. The circuits of relay R are closed through the ground.
  • the starter motor relay is adapted to actuate a contact CR INSERTED in the starter switch control circuit CD.
  • the system operates as follows:
  • the energization of relay R is prepared.
  • the closing of contact CF associated with the gear-change selector lever L causes energizing current to be supplied to the winding R of relay R, thereby closing its contact CR.
  • the starter motor switch which may comprise an electromagnet controlling the axial translation of the starter pinion, is then energized and the motor is started.
  • the alternator A driven by the engine torque supplies current to the second winding R of the starter relay through the medium of the three diodes D.
  • This winding R reduces to zero the magnetic field reduced by the first winding R, thus opening the contact C and preventing the operation of the starter motor when the engine is revolving.
  • this invention is applicable regardless of the number of phases of the alternator A, the number of diodes D being varied accordingly.
  • the capacity of these diodes is selected as a function of the current absorbed by the winding R of relay R.
  • relay R It may be desired to retard the deenergization of relay R immediately as the engine begins to rotate, so as to prevent the engine from stalling just after it is started.
  • the relay R will be equipped with a known time-lag device consisting either of capacitors or, as shown in the FIGURE of a retarding ring T surrounding the core of said relay.
  • starter motor control relay further comprises a time-lag device for retarding the deenergization of said relay.
