the pressure resulting from the screwing in action,
engages into the space of the next teeth.
At the end of this translation movement, that is just
before the complete cycle, the contacts of the enga-
ging relay close and the starting current is inserted .
The rotor is now revolving and because of the heli-
cal groove pushes the pinion (which cannot now
turn) deeper into the crown wheel right against the
armature spind le.
When the pinion is fully home it cannot move for-
ward any further and is so forcicly coupled with the
rotor shaft through the free wheel and the en-
trainer. The starter motor can now spin the engine
(fig. 188 /8).
Disengagement
When starting, the engine rotates faster than the
starter motor, the forced pinion-armature shaft cou-
pling is accord ingly taken off the free wheel thus
protecting the armature from an inadmissible num-
ber of revolutions. The pinion will stay engaged un-
til the engaging lever stays in its engaged position .
Only when the starter button is disconnected , the
coupling lever, en trainer, and the pinion return to
their idle position till the next starling operation, and
this irrespective of the vibrations caused by the run-
ning engine.
Free roller wheel
For safety's sake, translation type starter motors are
equipped wi th a free wheel (188 / 9) to engage the
pinion with the driving device (entrainer) so that
when the armature shaft rotates the pin ion is driven
