The invention relates to a solenoid switch for starting devices for starting internal combustion engines, comprising a joint () between assembled parts of the solenoid switch. The invention is characterized in that the joint is formed in such a way that a direct penetration of spray water is prevented and pressure compensation is enabled.

Solenoid switch

A power supply system for starter devices has an energy storage unit, a starter device supplyable with electrical energy from the energy storage unit, a power supply line which carries the electrical energy from the energy storage unit to said starter device, a disconnection switch between the energy storage device and the starter device, the disconnection switch being located reversibly and directly on the energy storage unit.

Starting device for an internal combustion engine, especially of a motor

The apparatus for controlling an electrical starter motor for cranking a cranking mechanism of an internal combustion engine to start the engine includes a circuit for making an electrical connection between a voltage source and the starter motor by which the starter motor is coupled with a cranking gear of the engine by means of a shiftable transmission when the circuit is energized and an electronic control unit for controlling at least one of a voltage, a current and an on-time of the electrical starter motor in a stepwise manner in a two-stage control process including a first stage in which the starter motor is coupled with the cranking gear and operated at a reduced rotation speed to reduce wear. The electronic control unit is electrically connected between the voltage source and the starter motor and is an electronic relay that includes a central processing unit and at least two electronic power switches for switching the voltage of the starter motor.
