Setting tool for setting a downhole tool

A setting tool for use with a downhole tool, the setting tool having a run-in position and a set position, the setting tool comprising:

• a housing having a housing upper end, a housing lower end, a housing wall having a housing inner surface defining an axially extending housing inner bore;
• a setting mandrel having a mandrel upper end, a mandrel lower end, a mandrel wall having a mandrel outer surface and a mandrel inner surface, the mandrel inner surface defining an axially extending mandrel inner bore, the mandrel upper end being connected to the housing lower end;
• a piston comprising an upper open end and a lower closed end, at least a portion of the piston being disposed in the housing inner bore, and the at least a portion of the piston comprising a piston head in sealing engagement with the inner surface of the housing wall, the piston having defined therein a power charge chamber extending between the upper open end and the lower closed end, the power is charge chamber being in fluid communication with the housing inner bore via the upper open end, the piston configured to be slidably movable axially relative to the housing and the setting mandrel;
• a power charge, at least a portion of the power charge being disposed in the power charge chamber;
• and
• a crosslink sleeve supported about the mandrel outer surface,
• wherein the setting tool is actuated upon ignition of the power charge to transition from the run-in position to the set position;
• in the run-in position, the crosslink sleeve is secured to the setting mandrel such that the crosslink sleeve is stationary relative to the setting mandrel;
• and
• in the set position, the piston is moved axially relative to the housing towards the mandrel lower end, and the crosslink sleeve is shifted axially, by the axial movement of the piston, relative to the setting mandrel towards the mandrel lower end.
