摘要
A portable liquid gas cylinder is described, of the type comprising a float device (18, 19, 21) which, when a pre-set level of liquid gas is reached in the cylinder, activates means (7) designed to interrupt the gas supply, the said cylinder being characterised in that it includes means (7,12,15,16) designed to allow opening for the passage of gas only if the cylinder is in a position in which the said float device can operate correctly.;In particular valve means (7) are provided that close the gas inlet pipe, said valve means being movable between a first position in which they open the said gas inlet pipe (5) and a second position in which they close the said pipe, said valve means being subject to the pressure of the incoming gas that tends to move them to the closing position of the said pipe, gravity means (15,16,14) designed to cut off the said valve to prevent its movement to the opening position of the said pipe also being fitted, which said gravity means only cut off the said valve when the cylinder is in the correct position to allow correct operation of the said float device..
