Abstract
A combination breakaway and swivel coupling for vehicle fueling systems is disclosed. The coupling includes a body having a swivel connection at one end and a breakaway connection at the other end. The swivel is directly connected to a vehicle fueling nozzle and the breakaway coupling is connected to the supply hose of the fueling system. The swivel coupling is a ball-and-socket type coupling which permits the nozzle to be moved in all directions with respect to the supply hose for convenient positioning of the nozzle in the vehicle during fueling and hanging of the nozzle on the pump when the unit is not is use. The breakaway coupling automatically separates in the event that the vehicle drives away without removing the nozzle and prevents damage to the hose and the pump structure. Automatic shutoff valves close when the breakaway coupling releases to prevent pollution or hazardous spills of fuel. One embodiment utilizes a frangible connection which fractures and releases when breakaway occurs. Three other embodiments illustrate a resilient type connection which permits reassembly without replacement of any component parts.
