    Abstract: The system comprises a low-voltage electrical supply (1), inductive voltage-increase means (CW, C), a plurality of plugs (SP), and distribution means (2, T) for allowing the selective supply of high voltage to the plugs (SP) through the voltage-increase means (CW, C). These latter comprise a low-voltage winding (CW) through which current flows each time a spark is produced in at least one plug (SP), and a plurality of coils (C1 - Cn) each of which is associated with a respective plug (SP1 - SPn). Each coil includes first and second windings (W1; W2) magnetically coupled together, the second winding (W2) being connected electrically to the plug (SP). The distribution means (2; T1 - Tn) are also adapted to connect the first winding (W1) of one or more of the coils (C1 - Cn) selectively to the low voltage winding (CW) and to allow current to flow through the said windings (CW, W1) to create the spark in the plugs (SP) connected to the said coils (C).

    Abstract: An electromagnetic device for controlling the supply of current to an electric starter motor includes a pair of fixed contacts on a support for connection to a power supply and a starter motor, respectively. A movable contact which is adapted to engage both fixed contacts is carried by a movable core of an electromagnet so that upon energization of the electromagnet, the movable contact engages both fixed contacts to complete the circuit to the starter motor. A spring is provided for biassing the movable contact away from the fixed contacts upon de-energization of the electromagnet. A flexible braided conductor is permanently connected between the movable contact and one of the fixed contacts to provide an equipotential electrical connection therebetween.

    Abstract: The system includes a direct-current voltage supply (30), an electric motor (2) for rotating a movable pinion (6), and an electromagnetic operating device (3) including a solenoid (11) and an associated movable core (10). The core (10) moves the pinion (6) towards an operating position in which it can be coupled for rotation with a rotary member (7) of the internal combustion engine. The connection between the electromagnetic operating device (3) and the voltage supply (30) is controlled by an electronic unit (ECU) which measures the current flowing in the solenoid (11) by means of a portion (11d) of the wire forming the solenoid, which portion is bent and preferably twisted, and acts as a resistive shunt.

    Abstract: The device comprises two fixed contacts (5, 5a), a movable assembly (17; 18, 19, 21, 24) coupled to the central portion of a movable contact (22) the free ends (40) of which can cooperate with the said fixed contacts (5a), and a control electromagnet (3) comprising a solenoid (10) and a movable core (15) displaceable from an initial rest position (Figure 1) to a final position in which it strikes a stop element (8) carrying with it the movable assembly (17) so as to bring the end (40) of the movable contact (22) against the fixed contacts (5a) before reaching the final position. The movable contact (22) can flex resiliently like a beam under the effect of its engagement with the fixed contacts (5a). When the core (15) strikes the stop element (8), the fixed contacts (5, 5a) oscillate about their normal working positions. The movable contact (22) is made in such a way that, as the fixed contacts (5, 5a) start to oscillate its free ends (40) follow the movements of the fixed contacts (5, 5a), its acceleration (a1) in its own mode of vibration being greater than the acceleration (amax) of the fixed contacts (5, 5a) and its amplitude of oscillation (s1) being greater than the amplitude of oscillation (s) of the fixed contacts (5, 5a).
