Patent ID: 6971682

Claim:
A coupling assembly for fuel transfer comprising: a first inner conduit attached to a first ferrule adapter, said first ferrule adapter comprising a first inner conduit sealing mechanism; a second inner conduit attached to a second ferrule adapter, said second ferrule adapter comprising a second inner conduit sealing mechanism; an inner conduit coupling that engages said first inner conduit sealing mechanism and said second inner conduit sealing mechanism, thereby connecting said first inner conduit to said second inner conduit, said inner conduit coupling comprising: a first inner conduit coupling half and a second inner conduit coupling half, said first inner conduit coupling half connected to said second inner conduit coupling half at a first end to allow for opening and closing of said inner conduit coupling; a latch system that secures said first inner conduit coupling half to said second inner conduit coupling half at a second end when the said inner conduit coupling is in a closed position; and an indication device that closes into a locked position only when said latches secure said first inner conduit coupling half to said second inner conduit coupling half; a first outer conduit surrounding said first inner conduit, said first outer conduit attached to said first ferrule adapter, said first ferrule adapter comprising a first outer conduit sealing mechanism; a second outer conduit surrounding said second inner conduit, said second outer conduit attached to said second ferrule adapter, said second ferrule adapter comprising a second outer conduit sealing mechanism; an outer conduit coupling that engages said first outer conduit sealing mechanism and said second outer conduit sealing mechanism, thereby connecting said first outer conduit to said second outer conduit, said outer conduit coupling comprising: a first outer conduit coupling half and a second outer conduit coupling half, said first outer conduit coupling half connected to said second outer conduit coupling half at a first end to allow for opening and closing of said outer conduit coupling; a system of latches that secure said first outer conduit coupling half to said second outer conduit coupling half at a second end when the said outer conduit coupling is in a closed position; and an indication device that closes into a locked position only when said latches secure said first outer conduit coupling half to said second outer conduit coupling half.
