Diver’s Air Resevoir
It has been found that with the
downward stroke of the diver’s air pump by either a lever action or rotary
action a rush of air was notice in the diver’s helmet. This was not the case
when air was supplied to the diver by a compressor which in turn charged an air
bank or air receiver.
In order to relieve any discomfort to the diver, German makers of Standard
Diving Equipment introduced a small air reservoir in the diver’s air line
between the pump and the air supply hose. These were made of copper or steel,
the copper ones lasting much longer as any moisture could condensate inside the
receiver and turn the metal rusty. A small valve was fitted to the base of the
receiver by which water could be drained off.
A pressure gauge was fitted to the top of the receiver. In the picture above the
receiver can be seen to the rear of the diver.
A German Air receiver made from copper on a steel stand, to the rear of the
receiver are two hose connections the lower one being for incoming air from the
pump and the upper one, air going to the diver.
