ABSTRACT:
A valve assembly includes a receptor valve assembly and an insert valve assembly each defining a normally closed fluid passage. The insert and receptor valve assemblies each include a valve activation structure engageable with one another and having corresponding helical grooves and splines for opening the receptor and insert valve assemblies upon engagement of the valve activation structures and rotation of the insert valve assembly relative to the receptor valve assembly wherein their respective fluid passages are interconnected. The insert and receptor valve assemblies are configured to provide substantially no fluid passage therebetween when closed, thereby providing little or no spillage of fluid when disconnecting the insert and receptor valve assemblies.
