A flexible connector apparatus used to join two stiff non-deformable members, such as piping. The apparatus is provided with one or more flexible sections or assemblies each utilizing a bellows of a rolling cuff type connected between two ridge members, with the bellows being supported by a back-up ring, such that only the curved end sections of the bellows are unsupported. Thus, the bellows can be considered as being of a tube-shaped configuration and thus have high pressure resistance. The components of the flexible apparatus are sealed or welded one to another such that it is fluid tight.

1. A flexible connector apparatus for interconnecting substantially rigid members and having at least one flexible assembly, and connector means connected to said flexible assembly adapted for connection with associated rigid members; said flexible assembly comprising: a single flexible element having a torus-shaped cross-section defining a space therein and having a pair of spaced substantially flat end sections, a longitudinally extending substantially flat body section, and a pair of curved sections each interconnecting said body section with one of said end sections; a pair of spaced members fixedly secured to said spaced substantially flat end sections of said flexible element; and a back-up member positioned in contact with said substantially flat body section of said flexible element, said back-up member having a longitudinally extending length greater than said flat body section of said flexible element. 2. The apparatus of claim 1, wherein said single flexible element is of an annular configuration. 3. The apparatus of claim 1, wherein said single flexible element is of an annular configuration, wherein said pair of spaced members are annular in shape, and wherein said back-up member has a ring-like shape. 4. The apparatus of claim 1 wherein said pair of spaced members are positioned radially inwardly of said flexible element, and wherein said back-up member is positioned radially outwardly of said flexible element. 5. The apparatus of claim 1, wherein said single flexible element is of an annular configuration, wherein said pair of spaced members are positioned about an outer surface of said annular flexible element, and wherein said back-up member is positioned within said annular flexible element. 6. The apparatus of claim 1, additionally including a plurality of flexible assemblies connected in a series relation such that a flat end section of one flexible element of one flexible assembly is secured to one of the spaced members to which a flat end section of a flexible element of an adjacent flexible assembly is secured. 7. The apparatus of claim 6, wherein each of said assemblies utilize a common back-up member. 8. The apparatus of claim 6, wherein two of said series connected flexible assemblies are secured to said connector means. 9. The apparatus of claim 8, wherein said connector means are secured to said one of said spaced members of an adjacent flexible assembly. 10. The apparatus of claim 1, wherein said curved sections of said flexible element has an angle of revolution between two points thereon in the range of about 30° to about 90°. 11. The apparatus of claim 10, wherein said angle of revolution is about 60°. 12. The apparatus of claim 1, additionally including fluid flow turbulance reducing means. 13. The apparatus of claim 12, wherein said flexible assembly is of an annular configuration, and wherein said turbulance reducing means extends through an annular opening in said flexible assembly. 14. The apparatus of claim 13, wherein said turbulance reducing means comprises a tube-shaped member extending through said flexible assembly, and a flange-shaped member secured to said tube-shaped member. 15. In a connector apparatus for interconnecting substantially rigid members and having at least one flexible assembly adapted to be connected to said members; the improvement comprising a flexible connector assembly composed of: a single flexible element having a torus-shaped cross-section defining a space therein and having a pair of spaced adjacent substantially flat end sections, a longitudinally extending substantially flat body section, and a pair of curved sections each interconnecting said body section with one of said pair of end sections, said end sections being adapted to be secured to associated rigid members; and a back-up member positioned in contact with and extending at least along said substantially flat body section of said flexible element; whereby only said curved sections of said flexible element undergo unsupported expansion or contraction upon movement of associated rigid members. 16. The improvement of claim 15, wherein said flexible element is of an annular configuration. 17. The improvement of claim 15, additionally including a pair of spaced members fixedly secured to said spaced substantially flat end sections of said flexible element, said spaced members being adapted to be secured to associated rigid members. 18. The improvement of claim 15, wherein said back-up member is positioned radially outwardly of said flexible element. 19. The improvement of claim 15, wherein said back-up member is positioned radially inwardly of said flexible element. 20. The improvement of claim 15, wherein said curved sections of said flexible element each has an angle of revolution between two points thereon in the range of about 30° to about 90°.
