Abstract
A quick and dry coupling for coupling together devices such as fluid lines. One embodiment of the coupling includes a pair of heads in which is provided mating members having mating surfaces for moving the mating members in opposite directions away from one another towards an open position and to permit movement of the mating members towards one another when the pair of mating members are turned in the opposite direction relative to one another, a latch coacting between the heads for selectively being movable to an unlatched position, to an intermediate position, and to a latched position for providing the attached condition of the coupling. Springs are provided for moving the pair of mating members into a closed position in which fluid flow is stopped and the latch is moved from the latched position to the intermediate position. In another embodiment of the coupling the mating members are fixedly held against turning movement relative to one another, and separate cams are respectively operably coupled between the heads and the mating members to cause the mating members to move to an open position upon turning movement of the heads.
