Abstract
A bottle charged with a gaseous material intended to be discharged through a range of temperatures but not outside that range, has a valve through which the gaseous material is to be directed. The valve has at least a part wholly inside the bottle, which part has a restricted port through it through which the gaseous material passes to issue from the valve, and a thermally responsive member adapted to block the port when the temperature of the interior of the bottle is outside the range. Preferably, the gaseous material is both introduced to the bottle and discharged from the bottle through the same valve, and the valve has a fill port of larger diameter than the restricted port, and an axially moveable actuating element, and the thermally responsive member is carried by the actuating element.
Claims14
A bottle charged with a gaseous material intended to be discharged through a range of temperatures but not outside that range, and a valve through which said gaseous material is to be directed, said valve having at least a part wholly inside said bottle, said part having a restricted port through it through which said gaseous material passes to issue from said valve, and a thermally responsive member adapted to block said port when the temperature of the interior of said bottle is outside said range.
A bottle charged with a gaseous mixture which condenses at a temperature to which said bottle is liable to be cooled in use, and a valve through which said gaseous mixture is to be directed, said valve having at least a part wholly inside said bottle, said part having a restricted port through which said gaseous mixture passes to issue from said valve, and a thermally responsive member adapted to block said port when the interior of said bottle is at a predetermined temperature sufficiently above said temperature of condensation as to ensure that condensation has not occurred, and to open said port when the interior temperature is above said predetermined temperature.
A valve having at least a part to be mounted wholly within a bottle containing a gas selectively introduced to and discharged from the bottle through the valve, said part wholly within said bottle having a restricted port through it through which said gaseous material passes to issue from said valve, and a thermally responsive member adapted to block said port when the temperature of the interior of said bottle is outside said range.
A valve having at least a part to be mounted wholly within a bottle containing a gaseous mixture including a volatile liquid, said mixture being selectively introduced to and discharged from the bottle through said valve, said part wholly within said bottle having a restricted port through it through which said gaseous mixture passes to issue from said valve, and a fill port of greater diameter than said discharge port, through which said gaseous mixture is introduced to said bottle.
A bottle charged with a gaseous material intended to be discharged through a range of temperatures but not outside that range, and a valve through which said gaseous material is to be directed, said valve having at least a part wholly inside said bottle, said part having a restricted port through it through which said gaseous material passes to issue from said valve, and thermally responsive means for blocking said port when the temperature of the interior of said bottle is outside said range.
