Abstract
A through the flowline or "TFL" tool selector has a base provided with a number of spaced flowline ports and a diverter tube shiftably mounted in a housing for selective communication with the flowline ports. The diverter tube is actuated by a reciprocable and rotatable piston and cam drive which shifts the diverter tube progressively from one flowline port to another. The piston is shiftable in a cylinder to which pressure fluid is supplied and then exhausted to effect actuation of the cam drive.
