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.
Claims10
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.
A gas dispenser apparatus for use with a high pressure gas cylinder having a closure valve body enclosing a spring-biased closure valve member, comprising a valve assembly connectable to the closure valve body and forming internally a gas discharge circuit downstream of the closure valve member, the valve assembly including, serially arranged in the gas discharge circuit, a distribution valve member and a pressure reducer, coupling means between the distribution valve member and the closure valve member, and manual operating means for manual operation of the distribution valve member and of the closure valve member.
