to 4c is that the inner elongated member of fig6 a to 6c has a fluid flow port or conduit 224 defined longitudinally therethrough the drive mandrel 250 the actuator screw 262 and the retrieving mandrel 266 are connected to each other in a fluid tight manner by the seals 234 at either end of the actuator screw 262 this prevents any fluid exchange between the fluid flow port 224 and the chambers 165 a 165 b 167 a and 167 b the elongated fluid chamber 212 is in fluid communication with the fluid flow port 224 such that fluid entering the coiled tubing can exit through the distal end of the retrieving mandrel 266 in particular the distal end of the bypass sleeve 218 is attached to the proximal end of the guide sleeve 138 through a threaded connection and the connection is sealed with the seals 116 interconnection ports 244 are defined between where the elongated fluid chamber 212 ends adjacent to the end of the bypass sleeve 218 and where the fluid flow port 224 begins at the proximal end of the drive mandrel 250 these interconnection ports extend through the guide sleeve 138 and the drive mandrel 250 generally perpendicular to the direction of the elongated fluid.
