Lever-assisted pinion in a starter motor

摘要

A starter motor in which the plunger of a solenoid switch supplying power to the starter motor also drives a lever through a return spring. The lever is connected on its other end to a pinion which moves along the output shaft of the starter motor to connect it to a ring gear of an engine to be started. The return spring biases the pinion away from the ring gear. The return spring and a drive rod acting on the lever are contained in a hollow of the solenoid plunger.
