Patent ID: 8496052

Claim:
A down hole well tool comprising a mandrel having a first passage therethrough; a slips/seal section movable on an exterior of the mandrel from a running in position to an expanded position for sealing against a production string; and a setting assembly for assisting in moving the slips/seal section from the running in position to the expanded position, the setting assembly including a setting device at least partially disposed within the mandrel and having a second passage therethrough comprising a threaded section, and a setting rod comprising a threaded section engaged with the threaded section of the setting device, wherein pulling on the setting rod expands the slips/seal section into sealing engagement with the production string and separates the threaded section of the setting rod from the threaded section of the setting device to remove the setting rod from the mandrel, the arrangement of the setting device and setting rod being that removal of the setting rod from the mandrel opens the first and second passages, the setting device remaining rigid with the mandrel upon removal of the setting rod.
