<p>The invention relates to a cylinder valve (2) having a built-in residual pressure valve, said valve being openable with a view to filling the cylinder via an additional operation of the manual control wheel. The valve (2) includes a closing valve consisting of a first seal (12) engaging with a first seat (14). The residual pressure valve consists of a second seal (30) which, as a result of the force of a spring (32), engages with a second seat (24). The first and second seats are fully formed and translatable (10). A rod (26) for controlling the seal (12) of the closing valve comprises an abutment (28) capable of engaging with the first and second seats (14, 24) with a view to opening the residual pressure valve via an additional movement of the control rod (26).</p> |
