Check valve assembly |
摘要 |
This invention relates to check valve assemblies in general, and more specifically to an easy opening fuel line check valve assembly, wherein a cage structure which supports a free floating ball valve allows a relatively weak spring to be employed for the closing bias while avoiding the buckling problem normally associated with weak spring elements in similar valve assemblies.
