ABSTRACT:
A breakaway coupling for a fuel supply hose includes a male tubular valve body interfitting with or female tubular valve body and defining a fuel supply passage, and the valve bodies enclose axially moveable spring biased valve members. The valve bodies are connected by releasable connecting means which provide 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. The valve bodies have cooperating peripherally extending and opposing cam surfaces effective to move the valve bodies from the connected position to the disconnected position in response to relative rotation of the valve bodies and cam surfaces.
