Abstract
A tool comprises a tool body having a bore, a secondary chamber within the tool body, a flow port between the bore and the secondary chamber; a cover component within the bore moveable between at least two positions along the length of the bore, and a control arrangement connected to control movement of the cover component within the bore. The control arrangement comprises a moveable piston and a guide component, one of which has a track and the other has a protruding element received in the track. In a first position, the cover component covers an entrance to the flow port, so that fluid flowing along the bore may not flow into the flow port. In a second position, the cover component does not cover the entrance to the flow port, so that fluid flowing along the bore may flow through the flow port and into the secondary chamber.
