The bellows is a device for delivering pressured (A mixture of gases (especially oxygen) required for breathing; the stuff that the wind consists of) air in a controlled quantity to a controlled location.
At its most simple terms a bellows is a container which is deformable in such a way as to alter its volume which has an outlet or outlets where one wishes to blow air.
The bellows differs from the (An ardent follower and admirer) fan in that it exerts much greater control in where it delivers the air.

 Atmos Clock: Replacement of Old Bellows
The bellows in an Atmos clock consists of a metal capsule that is designed to expand and contract easily, which makes it possible to wind the mainspring of the clock when the temperature or atmospheric pressure changes.
The new bellows is installed by placing it in the freezer for about two minutes until it contracts and then immediately place it inside the housing with the retaining spring placed in the center of it and screw the front cover back on (clockwise, in the opposite manner than it had been removed).
Since the new replacement bellows is slightly smaller in diameter than the housing, it is possible to cut an opening in the end of the housing, remove the existing bellows, and install a new bellows.

A bellows failure provides a route for the release of process fluids to the atmosphere via the pressure relief valve bonnet vent.
The telltale is a shuttle that normally allows the bonnet of a balanced bellows pressure relief valve (with intact bellows) to vent locally to atmosphere on a demand for the pressure relief valve to open.
The root cause of bellows failure should be investigated with the bellows and valve manufacturer (chattering, incorrect material specification, incorrect pressure rating, incorrect installation, incorrectly specified fatigue life, incorrect dimensional tolerances on bellows manufacture etc) to eliminate bellows failure so far as is reasonably practicable.
