Patent ID: 7784483

Claim:
A modular fluid arrangement comprising: a modular strut having an inlet body and an outlet body and defining a modular cage receiving area therebetween; a modular cage removably secured to said modular strut and received by the modular cage receiving area, said modular cage having a first open end and a second open end and defining an interior cavity, said modular cage further comprising an end piece defining a central opening and having an annular member extending therefrom, said end piece positioned adjacent said first open end of said modular cage such that said annular member is received within the interior cavity, wherein the interior cavity of said modular cage is in fluid communication with said inlet body and said outlet body of said modular strut; and a first sealing gasket, a second sealing gasket and a third sealing gasket for fluidly sealing said modular cage within the modular cage receiving area, a first axis passing through the interior cavity said first sealing gasket positioned between an inlet surface of said inlet body and said end piece, wherein said first sealing gasket is positioned about the first axis, wherein a plane is defined at the adjacent abutting surface of the inlet surface and the end piece through which the first axis passes, said second sealing gasket positioned around said annular member of said end piece for fluidly sealing said annular member within the interior cavity of said modular cage such that said second sealing gasket seals about a cylindrical surface circumferentially about the first axis, and said third sealing gasket positioned between an outlet surface of said outlet body and said second open end of said modular cage and about the first axis, wherein a plane is defined at the abutting surfaces of the said outlet surface and said second open end through which the first axis passes, wherein: said modular cage and said modular strut are free to expand and contract a predetermined distance in a telescoping action relative to one another in a longitudinal direction thereby maintaining a fluid seal therebetween, and the interior cavity of said modular cage is adapted to receive at least one check valve.
