摘要： In a starter for starting an on-vehicle engine, a solenoid is provided to push a pinion gear. The solenoid has an electromagnetic coil composed of a single coil and electrically separated from a motor circuit, a fixed core, and a plunger. Supply of excitation current to the electromagnetic coil allows the fixed core to be magnetized to attract the plunger. Hence, a movement of the plunger results in a push of the movable member toward the ring gear. A switch is provided in the circuit and has a contact, a movable core, and a switch coil functioning as an electromagnet attracting the movable core in response to supply of current to the switch coil. A movement of the movable core results in on/off switching operations of the switch. The switch is allowed to operate independently of the solenoid when both the switch and solenoid are controlled.

摘要： An engine starting apparatus includes a first and a second power supply path extending from a battery to an electric motor to start an engine. An electromagnetic switch has main contacts disposed in the first power supply path. A resistor is disposed in the second power supply path. A motor relay has relay contacts disposed in series with the resistor. A controller delays the time when the main contacts are closed to apply a full voltage of the battery to the motor until a given time lag has elapsed after the relay contacts are closed to supply electric current to the electric motor through the resistor. Specifically, when it is required to apply the full voltage to the motor to run the motor at a rated speed, the current does not pass through the relay contacts, thus resulting in no voltage drop, which ensures the stability in starting the engine.
摘要翻译： 发动机起动装置包括从电池延伸到电动机以起动发动机的第一和第二电力供给路径。 电磁开关具有设置在第一电源路径中的主触头。 电阻器设置在第二电源路径中。 电机继电器具有与电阻器串联布置的继电器触点。 控制器延迟主触点闭合的时间，以将电池的全电压施加到电动机，直到在继电器触点闭合之后经过给定的时间延迟以通过电阻器向电动机提供电流。 具体地说，当需要向电动机施加全电压以使额定速度运转时，电流不通过继电器触点，因此不会发生电压下降，这确保了启动发动机的稳定性。

摘要： A solenoid for a vehicle starter includes at least one coil with a passage extending through the coil. A plunger is slideably positioned within the passage and configured to move in an axial direction between a first position and a second position. The plunger includes a substantially cylindrical outer surface portion with a circumferential notch formed in the outer surface portion. The at least one coil may include a pull-in coil and a hold-in coil wound on a spool. A plate member is positioned at one end of the spool and is separated from the plunger by a radial distance. The radial distance varies when the plunger moves in the axial direction as a result of the notch moving in relation to the plate member. A sleeve member may be coupled to the plunger such that the sleeve member covers the circumferential notch formed in the plunger.
