Hi Rick.
My words were meant to cover floats, sensors,
valves and scuba regulators. I was trying to generically cover them
all.
Remember the float that activates in the tube in an
ambient and causes the air to turn on? Also the electric water sensors
that
do the same thing? In your case your rubber
diaphram is your sensor, and reg valve body is your valve. Just another way of
skinning
the same ambient cat. Yep, were on the same page
Rick.

Ah, ok, so we're on the same page after
all :-)
I thought you meant separate
valves, sensors, etc.

Hi Rick.
I wrote.....
"What all ambients have in common
whether they have an opening to the water (like in an upside down glass) and
use the rising water level to trip a float, valve or sensor which then activates their air tanks
to vent, or whether they are closed to the
water and use a valve or sensor, is that they use internal air pressure to
push back against the external water pressure"
You wrote....
"A
sealed cockpit obviates the need for a sensor of any kind since the
regulators themselves do the job for you (hence, the term
"regulator"). The demand regulator is a valve in itself. The
rubber diaphram in front of the mouth piece physically pushes a
lever that opens the valve".
That's what I said Rick. "whether they are closed to the water and use
a valve or sensor". The rubber diaphram in the reg IS the sensor and
the valve in the regulator body IS the valve.
