<p>A fluid coupling device has separable male and female sections. Each section has a ball valve mounted for rotational and axial movement relative to a housing. When the sections are joined together, each ball valve rotates automati-cally to a flow-permitting position. When the sections are separated, each ball valve rotates automatically to a flow-preventing position. The ball valves interfit with one another so that a minimum volume of fluid is lost when the sections are separated.</p> |
