Quick connect coupling

Claim 1

A QUICK CONNECT VALVED COUPLING COMPRISING A NIPPLE BODY AND A SOCKET BODY WHICH TELESCOPE TOGETHER AND WHICH EACH HAVE A COAXIAL HOLLOW STEM CLOSED AT ITS FORWARD END, SAID STEMS HAVING GENERALLY RADIAL PASSAGES EXTENDING FROM THEIR INTERIOR TO THEIR EXTERIOR AND BEING AXIALLY ALIGNED WITH THEIR CLOSED FORWARD ENDS JUXTAPOSED AND ADJACENT WHEN SAID COUPLING BODIES ARE TELESCOPED TOGETHER, LOCKING MEANS CARRIED IN SAID SOCKET FOR ENGAGING SAID NIPPLE BODY AND LOCKING THE COUPLING TOGETHER WHEN SAID NIPPLE AND SOCKET BODIES ARE TELESCOPED TOGETHER, AN ANNULAR EXTERNAL FORWARD STEM SEAL ON EACH OF SAID STEMS FORWARD OF SAID GENERALLY RADIAL PASSAGES THEREIN, AN ANNULAR EXTERNAL REARWARD STEM SEAL ON SAID NIPPLE STEM REARWARD OF SAID GENERALLY RADIAL PASSAGES THEREIN, A NIPPLE VALVING SLEEVE ON AND AXIALLY SLIDABLE ALONG SAID NIPPLE STEM AND HAVING ITS REARWARD PORTION SLIDINGLY AND SEALINGLY ENGAGING SAID REARWARD NIPPLE STEM SEAL IN ALL POSITIONS AND RESILIENT MEANS BIASING SAID NIPPLE VALVING SLEEVE FORWARDLY INTO A CLOSED POSITION AND INTO SEALING ENGAGEMENT WITH SAID FORWARD NIPPLE STEM SEAL, A SOCKET VALVING SLEEVE ON AND AXIALLY SLIDABLE ALONG SAID SOCKET STEM AND HAVING END PORTIONS AND AN ENLARGED BORE PORTION INTERMEDIATE ITS END PORTIONS AND INTERNAL ANNULAR FORWARD AND REARWARD SOCKET SLEEVE SEALS IN ITS END PORTIONS FORWARDLY AND REARWARDLY OF SAID ENLARGED BORE PORTION, RESPECTIVELY, AND WHICH SLIDINGLY AND SEALINGLY ENGAGE THE EXTERIOR OF SAID SOCKET STEM FORWARDLY AND REARWARDLY RESPECTIVELY OF SAID GENERALLY RADIAL FLUID PASSAGES THEREIN, SAID SOCKET VALVING SLEEVE BEING MOVABLE FORWARDLY FROM A CLOSED REARWARD POSITION ON SAID SOCKET STEM TO A FIRST FORWARD POSITION OF TELESCOPING SEALING ENGAGEMENT OF SAID FORWARD SOCKET VALVING SLEEVE FOR AND THE EXTERIOR OF SAID NIPPLE VALVING SLEEVE FOR ESTABLISHING A FLUID SEAL BETWEEN SAID COUPLING PARTS WHILE MAINTAINING A CLOSED CONDITION OF SAID VALVES IN BOTH COUPLING PARTS, SAID SOCKET VALVING SLEEVE BEING MOVABLE FORWARDLY TO A SECOND AND FURTHER FORWARD POSITION WITH SAID ENLARGED BORE PORTION OF SAID SOCKET VALVING SLEEVE RADIALLY OPPOSITE AND SPACED FROM SEALING ENGAGEMENT WITH SAID FORWARD SOCKET STEM SEAL AND WITH THE FORWARD PORTION OF SAID SOCKET VALVING SLEEVE IN TELESCOPING AND ABUTTING SEALING RELATIONSHIP WITH SAID NIPPLE VALVING SLEEVE WHILE MAINTAINING SAID NIPPLE VALVING SLEEVE CLOSED, SAID SOCKET VALVING SLEEVE BEING MOVABLE FORWARDLY TO A THIRD POSITION TO EFFECT OPENING OF SAID SOCKET VALVING SLEEVE WHILE MOVING SAID NIPPLE VALVING SLEEVE REARWARDLY TO AN OPEN POSITION THEREBY ESTABLISHING A CONTINUOUS FLUID PASSAGE THROUGH THE COUPLING AND WHILE MAINTAINING SAID FLUID SEAL BETWEEN THE NIPPLE AND THE SOCKET, A PROTECTIVE BLEED ORIFICE AND VENT IN THE FORWARD END OF SAID SOCKET STEM AND EXTENDING BETWEEN THE EXTERIOR SURFACE OF SAID SOCKET STEM FORWARDLY OF SAID FORWARD SOCKET STEM SEAL AND SAID FORWARD CLOSED END OF SAID SOCKET STEM FOR BLEEDING OFF AND VENTING AND RELIEVING DELETERIOUS PRESSURE ON SAID FORWARD SOCKET SLEEVE SEAL DURING ITS TRANSFER BETWEEN SAID NIPPLE VALVING SLEEVE AND STEM AND SAID SOCKET STEM, AN EXTERNAL COLLAR ON SAID SOCKET BODY AXIALLY SLIDABLE THEREON FROM A REARWARD COUPLING UNLOCKING AND VALVE CLOSING POSITION TO A FORWARD COUPLING LOCKING AND VALVE OPENING POSITION, SAID COLLAR HAVING COOPERATIVE ENGAGEMENT WITH SAID LOCKING MEANS AND SAID SOCKET VALVING SLEEVE WHEREBY AXIAL MOVEMENT OF SAID COLLAR WHEN SAID COUPLING BODIES ARE TELESCOPED TOGETHER SUCCESSIVELY ACTUATES SAID LOCKING MEANS TO LOCK THE COUPLING TOGETHER AND THEN MOVES SAID SOCKET VALVING SLEEVE FROM ITS REARWARD TO ITS FORWARDMOST POSITION.
