Abstract
A breakaway coupling for a fuel supply hose includes a male valve body interfitting with a female valve body for defining a fuel passage, and the valve bodies enclose axially movable spring biased poppet valve members. The valve bodies are connected by a permanent magnetic coupling system which provides for moving the valve bodies from a connected position to a disconnected position in response to a substantial axial tension force on the valve bodies. In one embodiment, the coupling system includes an annular strike member surrounding the fuel passage and a mating annular magnet member supporting a plurality of circumferentially spaced permanent magnets of rare earth materials. In another embodiment, the valve bodies define a vapor return passage with a poppet valve member and disposed either radially outboard or inboard of the fuel passage. The magnetic coupling system also simplifies reconnecting the valve bodies.
