Abstract
A coupling includes first and second housings, a valve element, and a guide link. The first housing is rotatable relative to the second housing. The first housing has helical cam slots and the second housing has linear cam tracks. The guide link is in the first housing and is fixed with the valve element. The guide link carries cam rollers. The cam rollers ride in the helical slots and the linear cam tracks. Rotation of the first housing causes rotation of the helical slots. The rotation of the helical slots induces the cam rollers to travel along the helical slots and along the linear cam tracks such that the guide link translates linearly. The valve element moves with the guide link between open and closed positions.
