DISPOSITIVO DI AVVIAMENTO PER MOTORI A COMBUSTIONE INTERNA E MOTORE DI AVVIAMENTO A COMANDO ELETTROMAGNETICO PROVVISTO DI TALE DISPOSITIVO.

摘要

An electromagnetically-operated starter motor has a movable electrical contact constituted by a metal plate (30)having, in one of its flat faces (A), a notch (44) adapted to define an apical region which is subject to stresses within its plastic range. A vibration damper is thus created within the movable contact and eliminates problems resulting from resilient impacts between the contacts.
