Abstract: An inline shock dampener apparatus is configured to absorb energy from encountered axial shock events and subsequently release this energy in a controlled fashion. The inline shock dampener apparatus can be included, for example, as part of a measurement while drilling (“MWD”) or other downhole drilling assembly, and dampens these shock events by absorbing shock energy into an absorbing medium such as springs or elastomers and hydraulically-suppressing the recoil energy stored during the said shock event. Additionally, the inline shock dampener permits fluid to flow through an internal fluid flow path with little or no change to the internal flow path's volume, pressure, or effective flowrate.
