ABSTRACT:
A gas tank evacuator (10) comprises an evacuator housing (12) into which a neck (80) of a gas tank (82) can be screwed and an elongated valve-removal rod (14) for slidably passing through the evacuator housing and engaging and unscrewing a stem-actuated valve (88) of the gas tank. An elongated valve actuator pin (18) slidably passes through the valve-removal rod to extend from lower and upper ends of the valve-removal rod for independently actuating the stem-actuated valve. The valve-removal rod is moved longitudinally by a valve-removal-rod lever (16) which is pivotally attached to the evacuator housing and valve-removal rod by pivot links (60). The valve-removal-rod lever is pivoted on the evacuator housing to drive a valve-engaging device at a lower end of the valve-removal rod into engagement with the-stem-actuated valve of the gas tank for its removal from the gas tank.
