US 11,448,017 B2 · Compensated elevator link

Abstract

A compensated elevator link is disclosed. In at least one aspect, the compensated elevator link comprises a plurality of cylinder housings and a rod having a plurality of ends, each end comprising a piston head adapted to be slideably received within one of the cylinder housings for defining first and second hydraulic cylinders. Each hydraulic cylinder has at least one annulus for receiving a non-compressible fluid. The rod comprises a passage for receiving a compressible fluid, wherein each piston head comprises at least one passage to allow selective displacement of the non-compressible fluid between the annulus of the cylinder housing and the passage within the rod during selective displacement of the hydraulic cylinders between a contracted condition to an extended condition for either compression or expansion of the compressible fluid by the non-compressible fluid.

Dependent claims

An elevator link arranged for use in providing a compensatory response to a load applied thereto, the elevator link comprising:

a first hydraulic cylinder and a second hydraulic cylinder configured operable with a piston rod by way of respective non-compressible fluids,
the piston rod having an internal chamber for accommodating a compressible fluid and at least a portion of the respective non-compressible fluids,
the first hydraulic cylinder and the second hydraulic cylinder arranged in operable association with the piston rod such that the non-compressible and compressible fluids are cooperable with each other so as to allow the elevator link to be operable toward and/or from one of an extended condition and a retracted condition in response to the load, wherein each cylinder comprises a housing and, wherein opposite free ends of the piston rod are slideably associated with a respective housing.
