Beschreibung
Zusammenfassung:	A constant motion pipe swivel joint having a greatly improved useful life without leakage of fluid from the joint. The swivel joint includes a plurality of sealing discs rotatably positioned between an outer joint member and an inner joint member. One side of each disc is coated with a material having a low coefficient of friction and the other side of each disc is bonded to a layer of elastomeric material such as rubber. The discs are pressed together by the inner and outer members to provide a seal which prevents leakage of fluid from the joint. The rubber stretches to allow small degrees of rotation of the joint without any slippage of one disc over another, and the surfaces of the discs are free to slip over each other to allow a large amount of rotation of the outer joint member relative to the inner joint member.
