Gas supplying assembly for connection to a high pressure gas container

摘要

The gas supply device is intended to be connected to a reservoir containing a gas under high pressure. The device comprises both a high pressure part (1) and a low pressure part (16), with each part having its own safety device (8,27). The two safety devices are connected together by an exhaust collector (10) with a single output (10) channelling the gas to the outside of the assembly. The low pressure part (16) comprises a hollow piston (18) with a deformable metal bellows, moving with little friction on a nozzle (20) of the high pressure part (1). A conduit (11) is formed in the body (2) of the high pressure part, connecting the inside of the piston (18) to atmospheric pressure.
