Patent ID: 7213616

Claim:
A diversion valve fluid coupling, for permitting alternate fluid flow operating positions, comprising in combination: a valve housing, having an inlet port portion and spaced first and second outlet portions, all of said port portions being connected via a housing central cavity, said first outlet port portion including an annular valve seat; an annular quick disconnect coupling mechanism attached to said housing second outlet portion; an annular static elastomer seal member interposed between said housing second outlet portion and said quick disconnect coupling member; an axially movable diverter valve assembly, comprised of operatively interconnected actuating and opposing valve assemblies, located within said housing central cavity, said actuating valve assembly, being adapted, in a first operating position, for a first sealing engagement with an adjacent annular side portion of said static elastomer seal member; said opposing valve assembly, being adapted, in a second operating position, for a second sealing engagement with said first outlet port portion annular valve seat; a biasing member, located within one of said housing central cavity and said first outlet port portion, for biasing said diverter valve assembly into said first sealing engagement, thereby blocking said second outlet port portion and concomitantly permitting fluid flow only from said inlet port portion into and through said first outlet port portion in said first operating position; and for said second operating position, a removable nipple member, adapted for removably mating with said annular quick disconnect coupling member and, upon full insertion thereof, axially abutting and translating said diverter valve assembly, against the force of said biasing member, into said second sealing engagement, thereby blocking said first outlet port portion and concomitantly permitting fluid flow only from said inlet port portion into and through said second outlet port portion, wherein said actuating valve assembly includes: a. an intermediate disc portion; b. on one side of said disc portion, an adjoining reduced diameter, generally-cylindrical, hollow, abutment portion, having spaced, peripheral, relief areas for permitting fluid flow, from said housing central cavity, into the inside of said abutment portion, with the outside diameter of said abutment portion being sized for a freely sliding relationship relative to the inside diameter of said static elastomer seal member; and c. on an opposite side of said disc portion, a first piece of a connecting portion, said connection portion being operatively interconnected with said opposing valve assembly.
