Patent ID: 7712788

Claim:
A connecting assembly for mobile refrigeration systems for connecting refrigerant lines each having a respective line end piece with a radial sealing surface being a flange to a further air-conditioning circuit component having a radial sealing surface, comprising: a first coupling piece having a bore formed therein and being moveably connectible to a first line end piece and the further air-conditioning circuit component; a sealing ring for being disposed between the radial sealing surfaces of the first line end piece and the further air-conditioning circuit component; a single screw for joining said first coupling piece and the further air-conditioning circuit component together such that the first line end piece and the further air-conditioning circuit component are connected to one another to have an aligned bore and by the radial sealing surfaces via said sealing ring; said single screw being disposed laterally offset from said bore in said first coupling piece; a non-compressible molding spaced apart from said single screw and for defining a spacer between said first coupling piece and the further air-conditioning circuit component; the first line end piece being disposed within said bore of said first coupling piece, the radial sealing surface of the first line end piece projecting from said first coupling piece and for facing toward the further air-conditioning circuit component; the first line end piece having a widened portion in a region of said bore of said first coupling piece, for fixing said first coupling piece in a rotationally secured and immovable manner with respect to the first line end piece; said first coupling piece having an annular collar for pointing toward the further air-conditioning circuit component on an end of said bore of said first coupling piece facing toward the further air-conditioning circuit component; said annular collar being assigned to a rear side opposite the radial sealing surface of the first line end piece and facing away from the further air-conditioning circuit component; in a fully-assembled state of the assembly, said annular collar presses against the rear side, and presses the radial sealing surface of the first line end piece onto said sealing ring.
