Abstract
Abstract The device comprises an assembly intended to be mounted on a closure valve of a high pressure container and comprises a manual control device operating a distribution valve in which the upstream end communicates with the closure valve, a pressure reducer and a safety device against over pressures between the distribution valve and an outlet for connection to a user circuit, as well as a manometer which measures the pressure upstream of the distribution valve. A pusher-rod operates the valve of the closure valve in response to a movement of the distribution valve.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
107 words
Gas distribution adapter and pressure reducer device for high pressure container including a closure valve, wherein said device comprises an assembly connectable to the closure valve and including: manual control means arranged to operate a distribution valve; an outlet for connection to a user circuit; and a pressure reducer disposed between the distribution valve and the connection outlet, said assembly including a body containing the distribution valve and a pressure reducer, and a mounting support for mounting on the closure valve, said support having a duct communicating with the distribution valve and containing a pusher-rod which, in mounting position, cooperate with the valve of the closure valve.
Claim 2
Dependent Claim
107 words
Gas distribution adapter and pressure reducer device for high pressure container including a closure valve, wherein said device comprises an assembly connectable to the closure valve and including: manual control means arranged to operate a distribution valve; an outlet for connection to a user circuit; and a pressure reducer disposed between the distribution valve and the connection outlet, said assembly including a body containing the distribution valve and a pressure reducer, and a mounting support for mounting on the closure valve, said support having a duct communicating with the distribution valve and containing a pusher-rod which, in mounting position, cooperate with the valve of the closure valve.
Claim 3
Dependent Claim
42 words
Device according to claim 1, wherein the mounting support comprises a first end for engagement with the closure valve of the container and a second end mounted in a recess of the body communicating with the downstream end of the closure valve.
Claim 4
Dependent Claim
31 words
Device according to claim 1, wherein the manual control means include a spindle whose rotation produces a translation movement of a pusher member which is operatively connected with the distribution valve.
Claim 5
Dependent Claim
