Abstract
Abstract A charging valve connector is comprised of a cylindrical receptacle body mounted in the wall of a tank and providing communication between the interior and exterior of the tank. A movable valve element is threaded within the receptacle body and is rotatable for causing its movement from an open position, wherein it is spaced from a valve opening in the receptacle body, to a closed position wherein it closes the valve opening to prevent flow of fluid between the interior and exterior of the tank. A bore extends through the valve element and provides communication from the exterior of the tank to the valve opening when the valve element is in its open position, thereby providing a line of communication from the exterior of the tank to its interior through the valve opening.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
A charging valve connector comprising a receptacle body adapted to be mounted on the wall of a tank and including a receptacle chamber and a valve opening providing communication between said receptacle chamber and the interior of said tank; a movable valve element threaded within said receptacle body and having an inner end extending within said chamber and an outer end adapted for coupling to a source of fluid; and a bore extending through said valve element and providing communication from said outer end into said receptacle chamber whereby fluid is free to flow through said bore into said receptacle chamber when said outer end is coupled to a source of fluid; said valve element being rotatable to cause its axial movement from an open position wherein said inner end is spaced from said valve opening to a closed position wherein said inner end closes off said opening to prevent the flow of fluid between said receptacle chamber and said tank, said bore including an enlarged diameter adjacent said outer end, an insert being retained within said enlarged diameter portion, said insert having a port extending therethrough.
