Quick acting fluid coupling

Abstract

Abstract A FLUID COUPLING HAVING INTERFITTING MALE AND FEMALE BODIES. THE FEMALE BODY CARRIES RADIALLY MOVABLE DETENTS TO LOCK THE MALE BODY IN POSITION, THE DETENTS BEING HELD INWARDLY BY SLEEVE MEANS. BOTH BODIES HAVE SPRINGPRESSED FLUID RETAINING VALVES WHICH ARE OPENED WHEN THE BODIES INTERFIT BUT CLOSE WHEN THEY ARE DISCONNECTED. THE FEMALE BODY HAS AN OUTER FIXED SECTION CONNECTED TO THE SLEEVE MEANS AND AN INNER MOVABLE SECTION WHICH CARRIES THE DETENTS. THE OUTER SECTION IS CONNECTED BY A RIGID CONDUIT TO THE FLUID LINE. TO DISCONNECT THE COUPLING, THE MALE BODY AND INNER SECTION OF THE FEMALE BODY ARE MOVED WITH RESPECT TO THE OUTER SECTION AND SLEEVE MEANS UNTIL THE DETENTS ARE FREED. IN ONE EMBODIMENT, THE SLEEVE MEANS IS MANUALLY RETRACTABLE TO RELEASE THE DETENTS FOR CONNECTING OR DISCONNECTING THE BODIES. IN THE SECOND EMBODIMENT, THE SLEEVE MEANS IS PART OF THE OUTER FEMALE BODY SECTION, AND AN ANNULAR OVERCENTER SPRING MAINTAINS THE TWO SECTIONS OF THE FEMALE BODY EITHER IN A DETENT LOCKING POSITION OR IN A POSITION WITH THE DETENTS FREED, SO THAT IT IS UNNECESSARY TO MANUALLY RETRACT THE SLEEVE MEANS IN ORDER TO RECONNECT THE BODIES.
