Patent ID: 8726936

Claim:
A cartridge coupling adapted to connect a pressurized fluid line between a vehicle or apparatus and a user, comprising an external housing within which a female semi-coupling is inserted, comprising a front valve assembly and adapted to receive a male semi-coupling being also equipped with a valve assembly, said housing comprising a fluid channel adapted to accommodate oil and decompression means, on said female semi-coupling, to moderate the pressure inside the line thus facilitating the operations of coupling and uncoupling the male semi-coupling to/from said female semi-coupling, said decompression means comprising a decompression valve placed in a substantially axial position at the end opposite to said female semi-coupling with respect to the front valve assembly and adapted to discharge the oil in said fluid channel, and further comprising a rear body, which is internally hollow and in which a balancing slider is housed, slidingly associated therewith, wherein a chamber adapted to be filled with pressurized fluid during the coupling operation is inside said rear body, being closed on one side by said balancing slider slidingly associated with said rear body, and in that said valve assembly has an inner cavity and is coaxial to said balancing slider and slidingly associated therewith, said balancing slider comprising an internal valve assembly in an axial position, adapted to put said chamber in communication with said inner cavity of said valve assembly.
