摘要

Integrated valve assembly ( 2 ) with a main body comprising: an internal gas passage for conveying gas between a gas inlet and a gas outlet; gas expansion means ( 10, 12 ) placed in the said internal gas passage between the said gas inlet and the said gas outlet; and a locking valve ( 9 ) used for controlling the release of the gas and comprising a rotary actuator ( 18 ) that can be operated by the user; characterized in that it further includes blocking means ( 17 ) that act on the rotary actuator ( 18 ) of the locking valve ( 9 ) so as normally to prevent any rotation of the said actuator ( 18 ). Portable ambulatory equipment, comprising a compressed-oxygen bottle ( 1 ) on which such an integrated valve assembly ( 2 ) is mounted, optionally a protective shroud for protecting the assembly ( 2 ) and a demand valve connected to oxygen therapy nose clips, to a flowmeter or to any other similar device.
