Abstract:
1. A breakaway coupling adapted for use with a flexible fuel supply hose having a fuel supply passage, said coupling comprising a first body member and a second body member coupled together and defining a fuel supply passage with an axis, at least one axially movable valve member within at least one of said body members and movable between an open position and a closed position relative to said passage, a coupling system releasably connecting said body members and providing for movement of said body members from a coupled position to an uncoupled position in response to a substantial axial tension force on said valve bodies, said coupling system including a permanent magnet unit mounted on said first body member, a strike member mounted on said second body member, said magnet unit including an annular ferrous metal magnet member surrounding said fuel supply passage and receiving a permanent magnet, said magnet member is threadably connected to said first body member, and said magnet unit attracting said strike member in said coupled position with an axial force sufficient to require an axial tension force of at least one hundred pounds to separate said body members to said uncoupled position.
