TWO-ELEMENT TANDEM FLEXIBLE CONNECTION Russian patent published in 2013 - IPC F16L27/103 

FIELD: machine building.

SUBSTANCE: flexible connection has protruding part attached to casing. Two or more annulus elastomeric flex elements are laid one over the other coaxially and are mechanically connected to attach protruding part to the casing in such a way so that flex element in parallel reacts to angular and axial shifts of protruding part relatively the casing so that tensile strength on protruding part sets each of flex elements at compression with the aim of separating and distributing the tensile strength between flex elements proportionally their axial stiffness. Consequently, the volume of total load is increased for the said casing size and total area in foundation and flex element lifetime is increased for the said load volume. Flex elements can have common rotation centre as well as flex elements can be located at one and the same side from rotation centre or at the opposite sides. There described are the versions of flex elements design.

EFFECT: provision of relative angular shift.
