US Patent No: 7669648

Polymer shock absorber for use with well head lubricator assembly

---

Abstract

---

A shock absorber for use with a lubricator assembly comprises a body made substantially of a polymer material. An end of the body is supportable by a cup. Upon plunger strike, the cup can travel upward in the lubricator assembly and cause the polymer body to deform and dissipate a force of impact caused by the plunger. The body can resiliently compress and expand to substantially an original form. Equalization slots on the body can enable fluid carried to the surface by a plunger to flow from the lubricator assembly.
