COMPACT CARTRIDGE COUPLING

摘要

The present invention relates to a compact cartridge coupling (1) of the type adapted to connect a pressurized fluid line between a vehicle or apparatus and a user, which coupling is of the type comprising a female semi-coupling (3) adapted to receive a male semi-coupling (50). The cartridge coupling (1) according to the present invention is characterized in that it comprises decompression means (16) adapted to moderate the pressure inside the female semi-coupling (3) thus allowing a male semi-coupling (50) under pressure to be coupled and allowing the male to be disconnected while leaving pressure in the user line. Moreover, the cartridge coupling (1) is characterized by a 3:1 hydraulic unbalancing system between the pressure force acting on the female valve assembly (4) and that acting on the male valve assembly (51).
