Abstract:
A quick connect/disconnect coaxial hose assembly for conducting two fluids therethrough, comprising:a male connector defining a first fluid flow passageway therethrough for a first fluid;a female connector having a socket region for receiving said male connector and defining a first fluid flow passageway therethrough for said first fluid whereby said first fluid flow passageways of said male and female connectors together define a first fluid conduit for said first fluid;a first outer tube member mounted upon said male connector and fluidically connected to said first fluid flow passageway of said male connector and said first fluid conduit for conducting said first fluid through said first fluid conduit;a second outer tube member mounted upon said female connector and fluidically connected to said first fluid flow passageway of said female connector and said first fluid conduit for conducting said first fluid through said first fluid conduit;a first inner tube member disposed interiorly of said first outer tube member and having an axially inner end disposed interiorly of said male connector for conducting a second fluid therethrough;a second inner tube member disposed interiorly of said second outer tube member and having an axially inner end disposed interiorly of said female connector for conducting said second fluid therethrough;a sleeve member fixedly mounted upon a first one of said axially inner ends of said first and second inner tube members, separably mounted upon said axially inner end of a second one of said first and second inner tube members, and fluidically connecting said axially inner ends of said first and second inner tube members together such that said first and second inner tube members and said sleeve member together define a second fluid conduit for said second fluid; anda joint retainer nut member mounted upon a first one of said male and female connectors and engaging a second one of said male and female connectors for connecting said male and female connectors together,whereupon disengagement of said joint retainer nut member from said second one of said male and female connectors, said male and female connectors, along with their respective outer and inner tube members, can be axially disconnected from each other so as to quickly disconnect said hose assembly, whereas upon axial insertion of said axially inner end of said second one of said first and second inner tube members within said sleeve member, axial insertion of said male connector within said socket region of said female connector, and engagement of said joint retainer nut member with said second one of said male and female connectors, said male and female connectors, along with said respective outer and inner tube members, can be axially connected to each other so as to quickly connect said hose assembly.
