Abstract
A ball valve type fluid coupling having identical interconnectable parts characterized by low fluid spillage during disconnection. The rotatable ball valve is axially displaceable by cam structure along the flow passage as the valve is rotated between open and closed positons which prevents the valve from passing through the plane of the coupling connection end during valve operation and the valve exterior surface includes a flat coupling connection end sealing surface substantially coplanar to the coupling connection end when the valve is closed to reduce trapping fluid and spillage.
