Abstract
The present invention relates to a compact cartridge coupling of the type adapted to connect a pressurized fluid line between a vehicle or apparatus and a user, the coupling comprising a female semi-coupling adapted to receive a male semi-coupling and a decompression element adapted to moderate the pressure inside the female semi-coupling thus allowing a male under pressure to be coupled and allowing the male to be disconnected while leaving pressure in the user line, the cartridge coupling being further characterized by a 3:1 hydraulic unbalancing system between the pressure force acting on the female valve assembly and that acting on the male valve assembly.
