ABSTRACT:
An evacuator housing ( 14) of a gas tank evacuator (10) receives a gas tank (12). A valve seal of a movable seal head (34) and a puncture seal (66) of the evacuator housing are clamped onto the gas tank at opposite ends by a hollow threaded shaft (32) to form a sealed test space (58) exteriorly of the gas tank at a valve (22) and a sealed evacuation space (68) exteriorly of the gas tank at a puncture spot (24). A pressure gauge (60) coupled to the test space rides on the seal head and a valve actuator in the form of a rod (40), passes through the hollow threaded shaft into the sealed test space. A puncturing mechanism (18) punctures the gas tank at the puncture spot. The sealed evacuation space is positioned vertically below the puncture spot and communicates with a carbon filter positioned vertically above the evacuation space so as to form a U-shaped trap (90).
