ABSTRACT:
A quick disconnect coupling device formed from a female coupling portion a male portion for mating therewith. The outside diameter of the male portion is equal to the inside diameter of the female portion from the axial outer end of the male coupling to a point less than the total distance of penetration and a reduced outside diameter axially inward thereof. Each coupling portion has a valve to close the portions when they are disconnected. The coupling portions are configured to have a difference between the inside diameter of the female coupling portion and the reduced diameter of the male coupling. The female coupling portion is free to rotate about a point of maximum penetration by the male coupling portion to permit quick disconnection upon application of force to the outer end of either of the coupling portions. The edge of the male coupling portion may be tapered inwardly to assist in the rotation.
