An integrated valve assembly and apparatus. The assembly has a main body that includes () an internal gas passage for conveying gas between a gas inlet and a gas outlet; () a gas expansion means placed in the internal gas passage between the gas inlet and the gas outlet; () 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.

Integrated valve assembly with means for blocking the actuator

A valve having a valve body ( ) including an internal chamber ( ) of axis (AA) having an upstream compartment ( ) of diameter (Dam) and a downstream compartment ( ) of diameter (Dav), with Dam<Dav. A fluid inlet orifice ( ) is formed in the wall of the valve body ( ) and opens into the upstream compartment ( ). A piston body ( ) that can move in translation along the axis (AA) inside the internal chamber ( ) and which is located between the fluid inlet orifice ( ) and a fluid outlet orifice, has a front face ( ) located on the same side as the fluid inlet orifice ( ), a rear face ( ) located on the same side as the fluid outlet orifice, and a lateral wall ( ) located between the front face ( ) and the rear face ( ). The lateral wall ( ) has a cylindrical first portion (P ) of diameter (D ) and a cylindrical second portion (P ) of second diameter (D ), with D <D and D <Dav.

Valve with wilder opening and pressure regulator equipped with such a valve

The assembly includes a body in which there is formed a bore (3) for letting in gas under pressure, containing an isolation valve (4) exposed to the gas under pressure, at least one pressure reducer (5), an element (9) for selecting and regulating the flow rate through at least one outlet (8) for gas at reduced pressure, and a tubular member (11) for controlling the isolation valve sitting on top of the body. The isolation valve is a spool (4) which can be moved back and forth in a transverse housing (26) in the body and the opposite ends of which interact directly with curved guide ramps (18, 19) formed by the tubular control member. The direct control of the isolation spool (4) by turning the tubular member (11) simplifies the architecture of the assembly and reduces the manufacturing and servicing costs thereof. The assembly is useful in transporting bottles of gas, especially of medical oxygen.
