Multi-plane swivel connector

Claim 1

A multi-plane and light of weight swivel connector for use in attaching a pair of fluid conveying members together and providing a fluid seal thereat, said connector including a pair of swivel portions that connect together at approximate ends, the end of one swivel portion being a male portion, while the end of the other swivel portion comprsing a female portion, said male portion extending within the femal portion to form a unitary joint, a double sealed connection provided at the unitary junction of the connection of the swivel ends together, said double sealed connection formed of a pair of seals provided between the male and female portions of the formed unitary swivel joint, an O-ring provided at each seal to form the fluid seal thereat, a retaining means provided within the connector for axial fixing of the swivel portions together but allowing them their swivel motion with respect to each other, said swivel connector useful for attaching in a fuel line, one end of the connector securing with a fuel hose, and the other end of the connector useful for securing with a dispenser nozzle or the like, said double sealed connection forming an inner and outer sealed bearing for the swivel connector, said inner and outer sealed bearings being stepped, with one 0-ring of the sealed connection having a lesser diameter than the other O-ring of the other sealed connection, the inner said O-ring being of a lesser diameter than the outer O-ring, said lesser diametered O-ring being formed to provide low temperature flexibility to assure a continuing fluid seal, there being opposing shoulder formed upon each of the male and female portions, and said inner O-ring being located intermediate the said shoulders, said male portion forming a surface outwardly of its formed shoulder, and said outer O-ring cooperating with the female portion and seating upon the formed surface, said outer O-ring being formed to provide increased resistance to abrasive wear, and the retaining means disposed proximate the inwardmost part of the male portion for attaching the male and female portions together, there being a ring seat formed upon and near the proximate end of the male portion, and another shoulder formed on the inwardmost part of the female portion, with said retaining ring engaging with said another shoulder and seating within the seat for securing the two swivel portions together at their unitary junction, said swivel portions being formed of die cast injection molding from a zinc-aluminum alloy that is rapidly chilled under pressure to retard dendritic growth, and said O-rings being formed of fluoro composition comprising one of a fluoro carbon and fluoro silicone.
