Abstract:
1. A swivel fluid breakaway connector for pivotally connecting a fluid line hose to a nozzle, comprising: a male swivel adapted to pivotally connect to a nozzle, said male swivel admitting fluid and having a centerline; a female swivel in fluid communication with said male swivel, said female swivel connecting with a fluid line hose, said female swivel pivotally connected to said male swivel, said female swivel turning upon said male swivel, wherein said female swivel capable of turning upon an axis at different angles relative to the centerline of said male swivel; said male swivel having a tubular shoulder, said female swivel also having a tubular shoulder, both said female swivel and said male swivel formed having a base, each base having a flat surface, each base of said swivels integrally formed with the respective tubular shoulder of said female and male swivels; said base of the female swivel and the base of the male swivel connected for laying flush against the flat surface of each other, said male swivel base having a race formed within its surface and extending in a circular configuration substantially around the perimeter of the surface of said male swivel base, said female swivel base having a detent formed therein and extending above the surface of said female swivel base, said detent extending into said male swivel base race, whereby said detent travels within said race to allow said female swivel to turn relative to said male swivel and to thereby vary the angle of said female swivel relative to said male swivel during usage, the proximate ends of the race forming a cam stop to prevent the female swivel from entering into axial alignment with the male swivel; a breakaway portion extending from said female swivel and in fluid communication with said female swivel and the adjacent section of the fluid hose; said male swivel, said female swivel, and said breakaway portion providing passage for fluid therethrough; said breakaway portion having two spaced apart check valves, a valve seat for seating of said respective check valves after decoupling of said breakaway connector, one of said check valves having an extension therewith to hold the check valves unseated from their respective valve seats and allowing fluids and vapors to pass therethrough during normal usage, said extension separating from said check valves during breakaway of said connector during abnormal usage wherein said check valves seat upon their respective valve seats and thereby ceasing flow of any fluid and vapors from the fluid line out of said breakaway and from the nozzle or out of the female swivel; said breakaway portion having connector mounts for securing said check valves therein, said connector mounts having an inner concentric passage allowing fluid flow therethrough; and said check valves having cooperating internal vapor passages, said vapor passages cooperatively connecting to said inner concentric passage of each connector mount to allow vapors to flow through said inner connected passage and out through said connector mount for return to the dispenser during normal fluid dispensing.
