1. An activation control device for use in a downhole tool, comprising:
a sealing ball movably positionable proximate to a check valve seat, the sealing ball and check valve seat positioned between a source of fluid pressure and a movable component, and the sealing ball and check valve seat forming a check valve that prevents the movable component from extending outwardly from the downhole tool during rotation when the sealing ball is seated in the check valve seat and permits the movable component to activate by extending outwardly from the downhole tool during rotation when the sealing ball is unseated in the check valve seat, wherein the sealing ball and check valve seat are fluidly coupled between an oil filled reservoir and a piston cavity, and wherein the piston cavity is coupled to the movable component for causing movement of the movable component,
wherein the sealing ball reaches the check valve seat to become seated due to reaching a predetermined revolution-per-minute (RPM) of the downhole tool, and becomes unseated when the RPM of the downhole tool is less than the predetermined RPM.
