Note the valve assembly which Is retained In the
bottom of the fork leg. Bleed holes are contained
In the valve stem. and In a sub~assembly at the top of
the stem. This sub-assembly incorporates a damper
valve, which acts as a restrictor.
Ollis contained In the fork sliding member, the level
of which
Is always above the valve assembly. On
compression of the fork the all is forced through
bleed holes or slots In the damper tube. As the
travel Increases the bleed apertures are progressively
sealed off by a plastic sleeve, and the damping
Increases until the stanchion Is trapped on a cushion
of oil, which acts as the final bump stop. During this
operatJO:1, a vacuum Is created in the space formed
between the bottom of the stanchion and the
damper valve. Oil is transferred Into this compart-
ment through the bleed holes In the damper tube.
On expansion of the forks, the oil In this newly
formed compartment Is compressed, the damper
valve closes, and the all Is bled through small holes
In the damper valve Itself, and then progressively
through the apertures In the damper tube. During
this
operation ollis transferred back In to the bottom
member, in readiness for the next compression of
the forks.
