ABSTRACT:
A slide rack is pivotally supported at one end thereof on a plunger coaxially with an operating lever. On the other hand, a trigger which is urged in a direction away from the slide rack by a release spring has one end thereof pivotally supported on an intermediate portion of the operating lever, and the other end of the trigger is releasably engageable with a rack portion of the slide rack.
For automatic shut-off fuel supply, the operating lever is pulled up and the fore end of the trigger is held in a rack portion of the slide rack to maintain a valve open position. As soon as a fuel tank is filled, the plunger is slided downward, whereupon one end of the slide rack is shifted downward with the other end slided along a lever guard. By this sliding movement, the trigger is released from the rack portion of the slide rack to return the operating lever automatically into a valve closing position.
