Abstract

The coupling is for railway wagon air lines. The connection is made between sleeves (12) which terminate the respective conduits, each sleeve being mounted within cage (8) incorporated in a coupling head. The sleeves are free to move axially, incorporated springs tending to move the cages and sleeves towards disengaged and engaged positions respectively. Both the cages and their associated sleeves are mounted so that a partial mechanical coupling gives rise to forward sleeve movement as the cages retract. A sliding sealed joint (39) may be provided between sleeves and conduits, a spring (42) acting on a conduit flange (41) being used to effect a sleeve advance.
