  • Patent number: 11092273
    Abstract: A coupling for transferring fluids is provided, having a housing and a nipple which can be fastened thereto and separated from the housing when a predetermined axial pulling force is exceeded, while overcoming a spring force, and having a fluid duct traversing the housing and the nipple, a housing-side and a nipple-side non-return valve and is routed in a radially guided manner around a vented cylindrical interior of the nipple. A closure mechanism comprises respective valve-side pins and a sleeve arranged between these pins, the sleeve being axially movable in the interior of the nipple and lockable to at least one of the pins by means of spring pressure-mounted locking elements so that, with the nipple fixed, the non-return valves are held open against their spring force, and, with the nipple released, the housing-side non-return valve is completely closed and the nipple-side non-return valve is at least partially closed.
