Cylinder Action, Double Acting
A double acting cylinder
compresses gas on the instroke and outstroke of the piston. This requires
suction and discharge valves on both ends (head end and crank end) of
the cylinder.
As gas is being compressed in
the head end on the outstroke, gas is entering the cylinder on the crank
end, with the process reversed on the instroke.
