Patent ID: 11441527

Abstract:
A starting apparatus for internal combustion engines, having a drive pinion for engagement into a ring gear of the internal combustion engine, an electrical rotary actuator and an electrical linear actuator, the rotary actuator to rotate the drive pinion and the linear actuator to slide a pinion, and the electrical linear actuator having a linear-stroke magnet that has a sliding armature is moved by a retraction winding, within the retraction winding, along a sliding armature axis, having a holding winding by which the sliding armature can be held in a retracted state. The linear actuator also actuates a switching apparatus to activate the electrical rotary actuator into a second actuation stage. A second retraction winding is connected in parallel with the first retraction winding, such that the first retraction winding can be shut off by a normally closed switch while a current path through a second retraction winding is closed.
