The volume booster with transmission ratio amplifies the outlet pressure at a 1 to 1 up to
1 to 6 ratio by a pneumatic pilot pressure, which has no constant bleed. That signal pressure
has 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.
