Abstract
A device () for facilitating the transport of an apparatus A along an upward or downward directed conduit or bore hole including a drill string () is described. The device () has a body () having an upper body portion () and a lower body portion () which are coupled together and movable axially relative to each other. A fluid flow path () internal of the body () selectively enables fluid to flow through the body (). A first valve systemlocated at a first end of the internal fluid flow path () is operable by a pressure differential between a region external of the body () and the internal fluid flow path (). A second valve system () is located at second end of the internal fluid flow path. The second valve system () is operable by relative movement between the upper body portion () and lower body portion (). One or more openings () are provided at an end of the body () downstream of the first valve system () through which fluid can flow or fluid pressure can be communicated to an apparatus A being transported by the device ().
