ABSTRACT:
An integrated valve assembly and apparatus. The assembly has a main body that includes (1) an internal gas passage for conveying gas between a gas inlet and a gas outlet; (2) a gas expansion means placed in the internal gas passage between the gas inlet and the gas outlet; (3) and a locking valve that is used for controlling the release of the gas. Also included is a rotary actuator that can be operated by the user. This rotary actuator includes a blocking means that acts on the rotary actuator to prevent rotation of the rotary actuator. The integrated valve assembly may be used in a portable equipment unit that includes a compressed-oxygen bottle on which the valve assembly is mounted, and may optionally include a protective shroud for protecting the assembly and a demand valve connected to oxygen therapy nose clips, to a flowmeter or to any other similar device.
