MOUTHPIECE FOR CLOSED CIRCUIT SYSTEMS

REBREATHER TECHNOLOGY engineers have developed a mouth piece, US Patent, for closed circuit "rebreather" systems that addresses two major problems in currently used equipment.

Problem one: The closed circuit system requires that the user be able to "close" the mouth piece prior to removing it from the mouth while in or under the water. Operation of current shut off valves is difficult and they allow sand and dirt to enter resulting in damage to the valve. The rotary cylinder valve design eliminates this problem.

Problem two: The location of the breathing gas over pressure relief valve. Most systems have located the valve on the counter lung. Water differential pressure makes the valve position sensitive. Locating the valve on the mouth piece eliminates this problem.

The REBREATHER TECHNOLOGY low profile mouthpiece is a rotary cylinder design using "O" ring seals and having no exterior access ports that will allow sand or foreign materials to interfere with sealing. The over pressure relief valve is a double valve body, one spring loaded and one free moving to insure the valve always seals. The mouth piece is easy to disassemble to allow easy cleaning. The large breathing bore of the mouth piece and breathing hoses provides additional counter lung volume and dampens breathing path surges.

The mouthpiece can be adapted to most full face masks.
