III - Air chamber (tube type tyres).
The air chamber
is a closed ring-like rubber structure with a valve,
which contains pressurised air.
Valve. The valve is a mechanical device to inflate/
deflate the tyre and maintain air pressure inside the
air chamber (or tyre in the case of tubeless tyres).
It consists of three parts: the valve closing cap (a)
(to protect the internal mechanism from dust and
guarantee air tightness), an internal mechanism (b)
and the base (c) (the outer lining).
Tubeless Inflater. An inflation system which simpli-
fies inflating tubeless tyres.
Beading. Operation which takes place during infla-
tion and ensures perfect centring between the bead
and the rim edge.
Bead pressing gripper. A tool intended for use when
mounting the upper bead. It is positioned so that it
engages the shoulder of the rim and maintains the
upper tyre bead inside the well. It is generally used
for mounting low profile tyres.
Air delivery regulator. Union allowing regulation of
the air flow.
Bead breaking. Operation that allows the tyre bead
to be detached from the rim edge.
