Apparatus for sending a line through a conduit

摘要

A line shooting air gun that carries a line down a conduit by creating a turbulent air flow in the conduit that keeps the line away from the drag inducing conduit sides. The turbulent air flow is created by a valve body that reflects the air flow a number of different times, uses at least two chambers for compression and reflection, provides an unbalanced flow of air and angles the air flow around a venturi breaking up any smooth flow. The line is carried by the turbulent air flow. An air drag system creates a serpentine line path producing drag on the line preventing line tangling when the air flow changes. A nozzle fitting allows different size adapters for different size conduits to be attached. A backpack with a rigid frame is provided for carrying an air tank. The rigid frame forms a stand for the tank when the backpack is not being carried. The frame includes a width plate that adjusts the width of the backpack shoulder harness to the user. The frame also includes a weight balancing mechanism that tilts the load forward to balance the load on the user.
