ABSTRACT:
A travel joint provides economical manufacture, installation, service, and operation thereof. The travel joint substantially reduces the number of parts potentially exposed to corrosive fluid, eliminates cavities wherein such corrosive fluid may become trapped, and substantially reduces the number of dynamic and static seals required for its operation. Additionally, a torque transmitting member is utilized to prevent torquing through threaded service breaks in the travel joint. In a preferred embodiment, a travel joint has a tubular upper case, a torque collar rotationally and axially coupled to the upper case, a tubular mandrel axially slidably received in the upper case and torque collar, and rotationally coupled to the torque collar, and an adapter which axially and radially inwardly retains the torque collar.
