Claim Text:
1. A hydraulic connection assembly for connecting one or more first hydraulic lines, of the type comprising a one piece body enclosing at least two second hydraulic lines, and at least one draining line connected to said hydraulic lines with pipes and, further comprising a coupling for each of said first hydraulic lines which is provided with an axially movable element axially movable with respect to said one piece body and adapted to actuate a line decompression means to decompress said second hydraulic lines, wherein said decompression means comprise at least one sealing member positioned on said movable element adapted to hydraulically seal said movable element against a fixed member of said coupling fixed with respect to said one piece body, and at least one or more niches mounted on said fixed member of the coupling, so that said element is movable between a first working position, in which said sealing member hydraulically seals against said fixed member, and a second decompressing position in which said sealing member is positioned at said one or more niches, no longer hydraulically sealing and allowing a fluid to pass to said draining line, and wherein the one piece body has a rear part, said fixed member of said coupling consists of an adapter having a substantially hollow cylindrical shape, said first hydraulic line being inserted into said adapter on which the coupling is placed, said adapter also being fixed with respect to said one piece body, said adapter comprising an end portion, on which said one or more niches are obtained facing the sealing member, and wherein said movable element comprises a substantially hollow, cylindrical rear body slidingly associated with said fixed member and partially inserted therein, and wherein a helical spring is housed at least in part within said one piece body, said helical spring being active between said adapter and said rear body and being configured to oppose the interpenetration of the rear body within the adapter.
