My invention relates to an air and water sepa
rator, and more specifically to one for separating
the air and water from gasoline and other hy
drocarbons.

a considerable quantity of water and air in an
emulsi?ed and partly homogenized condition.

compartment 4. To prevent this water from
passing on over and out through the tank, a ?oat
6 is provided which has a speci?c gravity that
causes it to sink in gasoline, but ?loat in water.
The ?oat 6 when raised by water, actuates a valve
20 which can be of any type which shuts o? the
inlet 2 until the slug of water has been bled oi!

of material is positioned in the tank between the
which has an inlet 2 and an outlet 3. The gaso
line or other hydrocarbons are forced‘ into the
tank through the inlet 2 and out through the out
let 3. To remove the water contained in the gaso
line or other hydrocarbons passing through the
tank -I, a compartment 4 is constructed directly
below the inlet 2 by welding to the bottom and
sides of the tank a ba?le 5. If the water which
is in large quantities such as a slug which is being
used to force the gasoline through the line,v en
_ ters the inlet 2, it settles to the bottom of the
'- inlet 2 and the outlet 3. This material has the
peculiar characteristic of separating water and
air from the gasoline, by changing the velocities
and pressures of the ?uid in its passage through
ba?ling and cleaving the ?uid. This breaks the
surface tension of the water particles, allowing
the water particle to coalesce and form globules
