  • Blockage removal apparatus and method
    Patent number: 8999070
    Abstract: The invention provides a method and apparatus for removing a blockage from a fluid conduit. An apparatus comprises a first portion containing a fluid volume separated from the fluid conduit via a controllable valve. The valve is cyclically opened and closed such that a pressure differential between the first portion and the fluid conduit causes a series of pressure pulses in the fluid conduit. The pressure differential is regulated to control the amplitude of the pressure pulses of the series.
