摘要：
A normally open check valve, incorporating a bell-shaped check valve member, and filter assembly incorporating same, wherein the specific gravity of the bell shaped member volume as defined by the throat, and exterior wall of the bell shaped member is less than one, and the bell shaped member is disposed adjacent a valve seat in a chamber with the throat opening thereof generally facing a liquid source, among other things. The low specific gravity for the bell shaped member volume may be attained by way of example, by the bell shaped member interior capturing and retaining a gas bubble when the throat of the member is exposed to a liquid-gas interface, or by a thin member covering the throat of the bell shaped member to encapsulate a gas bubble, or by a foamed synthetic resin material in the interior of the bell shaped member, or a combination thereof.
摘要（中）：
具有钟形止回阀构件的常开止回阀和包括钟形止回阀构件的过滤器组件，其中由喉部形成的钟形构件体积的比重和钟形构件的外壁小于1， 并且钟形构件设置在腔室中的阀座附近，其中喉部开口大致面向液体源。 钟形构件体积的低比重可以通过示例来实现，当构件的喉部暴露于液 - 气界面时，钟形构件内部捕获并保持气泡，或者通过薄构件 覆盖钟形构件的喉部以封装气泡，或者通过泡沫合成树脂材料在钟形构件的内部或其组合中。
