Integrated valve assembly with means for blocking the actuator

An integrated valve assembly with a main body comprising:

• a) an internal gas passage for conveying gas between a gas inlet and a gas outlet;
• b) a gas expansion means placed in said internal gas passage between said gas inlet and said gas outlet;
• and
• c) a locking valve used for controlling the release of the gas and comprising a rotary actuator that can be operated by the user, wherein said locking valve further comprises a blocking means that acts on the rotary actuator of the locking valve to prevent the rotation of said rotary actuator.

An apparatus which is portable, ambulatory, and weighs less than 2 kg, comprising a compressed-gas bottle onto which is fitted an integrated valve assembly wherein said integrated valve assembly with a main body comprises:

• a) an internal gas passage for conveying gas between a gas inlet and a gas outlet;
• b) a gas expansion means placed in said internal gas passage between said gas inlet and said gas outlet;
• and
• c) a locking valve used for controlling the release of the gas and comprising a rotary actuator that can be operated by the user, wherein said locking valve further comprises a blocking means that acts on the rotary actuator of the locking valve to prevent the rotation of the said rotary actuator.
