ABSTRACT:
A quick disconnect female coupling is provided with a lever-operated valve. The lever operates a cam inside the coupling which pulls open the valve assembly of the female coupling and pushes a plunger which opens the valve of a male coupling which is connected to the female coupling. The push-pull action of the cam provides straight linear forces for opening the valves, and the cam is positioned within a large flow passage in the female coupling rather than near the valve.
