<p>A tap for a bottle of compressed or liquified gas has fitted therein a flow limiter in the form of a cartridge internally comprising a first, upstream chamber receiving the gas coming from the bottle, a second, downstream chamber opening into a supply line and a calibrated passage connecting the first and second chambers. A flow control assembly comprising a valve associated with a calibrated control element and an expansion chamber is preferably arranged to control the flow between the first and second chambers. The tap has particular utility in bottles for transfer of toxic and/or spontaneously inflammable gases, since it prevents major leaks from such bottles or from supply lines fed therefrom.</p> |
