Abstract
A coupling and method are provided that include a coupler and nipple. The nipple has a valve in a normally-closed position and an outer peripheral surface with a plurality of spaced-apart, close-ended cam paths. The coupler has a valve in a normally-closed position and includes a set of latching balls for engagement with the cam paths to secure the coupler to the nipple. The coupler further includes a sleeve mounted thereon and movable between forward and retracted positions. In the forward position, the latching balls are forced into an inward position that prevents release of the latching balls from the cam paths, and in the retracted position, the latching balls are permitted to extend to an outward position enabling initial engagement with or disengagement from the cam paths. The coupler also includes a set of locking balls that prevents movement of the sleeve to the retracted position.
