Beschreibung
Zusammenfassung:	A diaphragm assembly for use with a filler valve including a central bellows, an upper mating structure and a lower mating structure. The central bellows has a first portion and a second portion. The upper mating structure matingly engageable in substantially sealed engagement with an outer surface of a valve body. The lower mating structure is positioned at the first end of the second portion and has an inner ring member, a first encasing structure and an outer encasing structure. The inner ring member comprises a rigid material. The first encasing structure encases the inner ring member and includes an inner annular sealing surface structurally configured to slidably engage the outer surface of the valve body. The outer encasing structure encasing at least a portion of the first encasing structure. The combination of the first encasing structure and the outer encasing structure completely encapsulate the inner ring member.
