  • Patent number: 9771913
    Abstract: In a method for actuating a starting device for an internal combustion engine, for the case in which the rotational speed of the toothed ring is below a limit value, first a stroke armature in a starter relay is moved and an electric starter motor is switched on after the starter pinion has engaged. If the rotational speed of the toothed ring exceeds the limit value, the starter motor is switched on before the starter pinion contacts the toothed ring.

  • Patent number: 8514038
    Abstract: The invention relates to a starter relay (19) for internal combustion engines, comprising a relay coil (27) and an armature (20), which interacts with a fork lever (21) by way of a driver (24) so as to toe-in a starter pinion, and comprising a contact bridge (34) which is to be actuated by the armature by way of a switch axis (32) and interacts with switch contacts (23a), wherein a coupling (33b) connects the switch axis and the armature such that they can be displaced with respect to each other to a limited extent. In order to ensure that welded contacts tear open and the neutral position of the fork lever is achieved when the relay is shut off, a pretensioned compression spring (26) is inserted between the armature (20) and the end of the fork lever (21).

  • Patent number: 6693503
    Abstract: A relay (10), in particular for a starter for an internal combustion engine, is proposed. The relay (10) includes a relay coil (13) and a solenoid armature (22) which can be moved when full battery current flows to the relay coil (13). A contact member (37) can be actuated by the solenoid armature (22), whereby an operating lever (31) is situated on the contact member (37). It is provided that a coupling element (46) connects the operating lever (31) and the solenoid armature (22) with each other in a manner that allows them to slide with limits.

  • Patent number: 5159908
    Abstract: A cranking device for internal combustion engines includes a permanently excited cranking motor and an electrical run-down brake, having a switching device (25) which, during the run-down phase of the cranking device, connects the connecting leads of the brushes (4, 4') of the cranking motor (1) to one another via a resistor (24). An additional winding of the engaging relay (15) of the cranking device is used as the resistor.
