cooling water or finned for air cooling. Some older design cyl-
inders use gaskets to isolate cooling water jackets from the
cylinder. This design exposes the user to breakage from exces-
sive cylinder water entrainment if the gasket fails. Most current
reciprocating specifications do not allow gaskets to be used in
the cylinder. A double acting cylinder is designed to compress
gas on both ends of the cylinder (crank end and cylinder head
end), while a single acting cylinder is designed for compression
