  • Power charge retention and centralizing device for a wireline pressure setting assembly
    Patent number: 9464495
    Abstract: The power charge of a wireline pressure setting assembly includes a barrier located adjacent an open upper end of the power charge. The barrier centralizes the power charge in horizontal applications to ensure the associated tool properly sets. The barrier also limits how much of the power charge can flow out of its housing in a horizontal application. The barrier can be porous or impervious to contain as much of the power charge in a small sub-chamber in the pressure chamber defined by the barrier. Once ignition starts in the power charge the barrier can be consumed or otherwise disabled for the normal functioning of the setting device to set a tool and release from the set tool in a normal manner.
