Zusammenfassung:	PURPOSE: A discharge valve assembly by operating a float in a fuel tank is provided to seal a tank outlet safely by using an elastomeric valve member in filling the tank, and to secure re-opening of the outlet by contacting the annular bead rim to the support plate in finishing filling and to the inclined surface of the cage in moving the float down while recovering fuel. CONSTITUTION: A float assembly(32) has an elastomeric valve disk(46) with an annular bead rim caged for limited lost motion movement on the top of the float. A rigid backing plate(50) for the valve disk is pivoted on a curved surface on the top of the float to ensure self-alignment of the valve disk on the vent port seat when the float is moved upward by the rising liquid level for closing the vent during refueling. As fuel is supplied from the tank, the float is dropped and the angled top of the cage is contacted to the bead rim on the valve disk to effect the peel-away re-opening of the valve. 플로우트는 그의 상부에서 제한된 공전 운동을 하도록 수용된 환상 비드 림을 갖는 탄성중합체 밸브 디스크를 구비한다. 밸브 디스크용의 강성 지지판은 플로우트의 상부의 만곡면상에서 회전하여, 연료 보급 과정에서 배출구를 폐쇄하기 위해 플로우트가 상승 액체 레벨 만큼 상측으로 이동할 때, 배출구 시트상의 밸브 디스크의 자동 정렬을 보장한다. 연료가 탱크로부터 공급됨에 따라, 플로우트는 하강하고 케이지의 경사진 상부는 밸브 디스크상의 비드 림에 접촉하며 밸브의 이탈 재개방을 실행한다.
