<p>A coaxial hose, dual plane, swivel breakaway assembly (30) for use in combination with a fuel dispenser apparatus (10') is disposed between a hose (12') attached to a fuel dispenser unit and a nozzle (16'). The swivel breakaway assembly (30) has body portions (32, 34) with a first, assembled condition (Fig. 5) and a second condition in which the body portions are separated (Fig. 7). A fuel valve (92) located in the dispenser-end body portion permits flow of fuel when the body portions are assembled and resists flow upon separation. An element (80) securing the body portions together releases engagement upon application of tension force above a predetermined maximum level to the hose and nozzle across the swivel breakaway assembly. In a preferred embodiment, the hose is coaxial, and a vapor valve (102) is also disposed within the swivel breakaway assembly.</p> |
