4.1.2 Machine function
Atmospheric air is drawn through a filter into the compression chamber of the block. The air is
drawn in during the downward stroke of the piston. It is compressed during the upward stroke. The
compressed air passes through the inter-stage cooling pipe into the second cylinder where it is fur‐
ther compressed.
