Underwater Breathing Apparatus With Pressurized Snorkel
US Patent:
5947116, Sep 7, 1999
Filed:
Jun 28, 1996
Appl. No.:
8/672447
Inventors:
R. Igor Gamow - Boulder CO
Dana L. Ruehlman - Boulder CO
Dana L. Ruehlman - Boulder CO
International Classification:
B63C 1116
US Classification:
12820111
Abstract:
An underwater breathing apparatus is provided for delivering air to a diver submerged to a depth between one and 12 feet. A pump delivers air at low pressure via an expandable air hose to a regulator worn by the diver. The air hose provides a reservoir of air for the supply the diver. Upon inhalation by the diver, the air pressure within the diver's lungs is reduced, thereby causing a tilt valve located within the regulator opens to allow air from the air hose to be supplied to the diver until the air pressure within the diver's lungs is equal to the air pressure generated by the pump in the air hose, which in turn causes the tilt valve to close. An exhalation one-way valve is also provided in the regulator to allow the diver to exhale without forcing the exhaled air back into the air hose.
