Air passage
When the air pressure in the final gear case becomcs higher than atmospheric pressure both air and
oil flow in the following passages.
*
Air
flows from
hole (A) to chamber (B)
and passes through the gap
between rib (RI)
and
bearing case
to
the atmosphere through
the
breather hole
I F ) .
Oil
passage
When
the fin J gear case pressure rises abruptly or when the gear case oil level changes during
cornering,
the gear
oil may sometime flows out into the air passage.
In
this
case,
the gear oil. which
has flown
into hole (A), goes
into chamber (B), where the oil
is
separated from the air.
Then, the air
flows
through the gap between rib
(RI)
and bearing
case
and
goes out
through the
breather.
On the
other
hand, the
gear
oil, when
the
gear
case pressure
is higher than atmospheric pressure, flows
through the gaps between ribs, (R
I),
(Rz)
and
(R3)
and bearing
case
and returns to the
gear
case from
gear oil return port (El.
