  • Lightweight breathing device
    Patent number: 5386824
    Abstract: A lightweight breathing device for underwater use, and in contaminated air is disclosed. The device employs a one-way valve which requires only one hand to effect operation, and a closure stem which is securely mounted against excessive air pressure from the valve when air is released therethrough from an attached air tank. The one-way valve includes two interfitting components, one of which is rotatable, and which provides air orifices that form an air connection upon rotation to permit the release of air from the air tank. In another embodiment, high pressure air from the air tank is passed into a piston operated pressure reducer prior to being released to the user.
