  • Latching system for maintaining position of component within a downhole drill string section
    Patent number: 6896050
    Abstract: A latching system for maintaining the position of a component within a downhole drill string section during operation of a drill string. One preferred latching system embodiment has a shoe member including a cavity for receiving a component, a chamber opening into the shoe member cavity, an engagement member movable in the chamber between a retracted position and an engagement position, a first passage in fluid communication with the chamber and extending to an end surface of the shoe member, and a second passage extending from an outer side surface of the shoe member to the first passage. A pressure differential between pressure in the first passage and pressure in the second passage alters the position of the engagement member.
