the lower vessel exceeds the pressure in
the upper tank and water is pushed up
the siphon tube
(C)
into the upper tank.
During brewing, a small amount of water
and sufficient water vapor remain in the
lower vessel
(D)
and are kept hot enough
so the pressure will support the column of
water in the siphon. When enough time
has elapsed that the coffee has finished
brewing,
(E)
the heat is removed and the
pressure in the bottom vessel drops, so
the force of gravity push the water down

into the lower vessel, through a strain-
er and away from the grounds,

ending
brewing. The upper tank is then removed
and the coffee is now
(H)
ready to be
served from the lower chamber (carafe).
Pull the chain
