Emergency breathing apparatus with holster released regulator valve

摘要

A short, compact pressure cylinder filled with compressed air under about 3000 psi operating pressure is provided with a scuba type breathing regulator attached to the top thereof. A quick release holster surrounds the cylinder and is easily attached to any flight suit or vest which may be worn by a user. Attached to the holster is a mouthpiece cover to keep the mouth piece and the breathing chamber of the regulator clean and free of debris. The apparatus is easily operated and automatically activated simply by pulling the cylinder from the holster in a single movement. This removal of the cylinder from the holster acts to simultaneously remove the mouthpiece cover and open a supply valve in the regulator, permitting air to be supplied to the regulator valve. The apparatus is sealed at the place of manufacturing and is designed to be virtually maintenance free.
