ABSTRACT:
An improved quick disconnect apparatus comprising a nipple and coupler and having significantly improved Cv or flow characteristics resulting surprisingly from certain specified design ranges of flow path areas in relation to the flow path area at the interior of the input to the quick disconnect, the interconnecting angles, and a high degree of dimensional match between components. The principal structural changes relative to the prior art are provided in the coupler stem and its relation with the components enveloping it. The invention provides a reduction in flow pressure drop of as much as 30 percent or more over the prior art for comparable size quick disconnects.
