Abstract:
A breakaway device for joining first and second portions of a dispensing hose of a fueling station, where the first dispensing hose portion is connected to the fueling station and the second dispensing hose portion is connected to a coupling that is adapted to removably connect to a vehicle during fueling, the breakaway device comprising:a) a pair of leg pipe members, each having a distal end and a proximal end, the proximal end of a first one of said leg members adapted to be connected to the first dispensing hose portion and the proximal end of a second one of said leg members adapted to be connected to the second dispensing hose portion; b) a frangible pipe member having an inlet end and an outlet end, the inlet end of said frangible member connected to the distal end of the first leg member and the outlet end of said frangible member connected to the distal end of the second leg member, said leg members oriented at an angle relative to said frangible member so that a bending moment acts on said frangible member when opposing forces pull the proximal ends of the leg members generally away from one another; and c) said frangible member constructed so as to fracture when sum of the opposing forces pulling the proximal ends of the leg members generally away from one another exceeds a predetermined value; and d) a first bracket attached to said first leg member and a second bracket attached to said second leg member, said first and second brackets adapted to receive a pneumatic line for operating a dispensing valve of the fueling station so that said pneumatic line is ruptured when said frangible member is ruptured and said first and second leg members are pulled apart.
