For machinery-related linear movement, the application of the piston
rod cylinders are many and varied. By alternating pressurisation of
the piston, the energy of the compressed air is converted into force
and movements.
Basic construction
is simple and robust. Design variations and supplementary equipment
are continually extending the range of applications.
Piston rod
cylinders both 'hold' and 'move' in open-circuit and closed-loop controlled
pneumatic motive power units.
