Abstract
A valve assembly for use in the coupling of two members. The first member has an exterior surface and an interior surface. The interior surface defines a coupling sleeve and a valve sleeve. A fluid passageway is in communication between the coupling sleeve and the valve sleeve. A valve is positioned in the valve sleeve. The valve is biased toward the fluid passageway by a coiled spring. A valve pusher having a first end and a second end is positioned in the coupling sleeve and the fluid passageway. The assembly has a second member having an outer surface, an inner surface and a terminal portion. When the second member is inserted in the coupling sleeve, the terminal portion engages the first end of the valve pusher causing the second end of the pusher to engage the valve to unseat the valve to allow unrestricted fluid flow between the first member and the second member.
