  • DOWN HOLE APPARATUS FOR GENERATING A PUSLING ACTION
    Publication number: 20120073878
    Abstract: A down hole apparatus for generating a pulsing action includes a tubular housing a rotating first mandrel with a first cam profile and a reciprocating second mandrel with a second cam profile, which engages the first cam profile. Upon rotational movement of the first mandrel, the first cam profile exerts an axial force upon the second cam profile to initiate a pulsing action by forcing the second mandrel away from the first mandrel. Springs bias the second mandrel back toward the first mandrel, thereby completing the pulsing action and maintaining the second cam profile engaged with the first cam profile.
