The volume booster amplifies the volume at a 1 to 1 ratio of
pilot pressure to outlet pressure. The pilot pressure has no
constant bleed and shows the same function as a spring in a
common regulator, generating counter pressure on the diaphragm.
This force is compensated by the outlet pressure on the
diaphragm's bottom side. The ratio of pilot pressure to outlet
pressure depends on the size of the operating diaphragms.
