Valve assembly
First Claim
1. A valve assembly for use in the coupling of two members, comprising, in combination:
- a first member having an exterior surface and an interior surface, said interior surface defining a coupling sleeve consisting of an annular wall having an open end and an opposed fluid passageway end and a valve sleeve, a fluid passageway positioned between said coupling sleeve and said valve sleeve, said annular wall defining a first annular shoulder, a second annular shoulder spaced from said first annular shoulder and a first annular groove positioned between said open end and said first shoulder, an annular ring positioned in said first annular groove, an annular lock assisting member positioned adjacent to said first annular shoulder, an annular chamfer member having a chamfer positioned between said annular ring and said lock assisting member and an annular pusher support ring positioned adjacent to said second shoulder;
a valve positioned in said valve sleeve, said valve being biased toward said fluid passageway by resilient means;
a valve pusher having a first end and a second end, said first end positioned in said coupling sleeve, said second end positioned in said fluid passageway;
a second member having an outer surface, an inner surface and a terminal portion, whereby when said second member is inserted in said coupling sleeve, said terminal portion engages said first end of said pusher causing said second end of said pusher to engage said valve to unseat said valve, thereby allowing fluid flow between said first member and said second member.

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.
