Abstract

Pipe cleaning apparatuses for oil and gas pipelines are disclosed, in which a shield with a cleaning device is moved forward through a stream of liquid in the pipeline. The shield forms one or several passages for a passing stream of liquid within the pipeline in order to build up a desired pressure and is provided on its rear side with braking means which prevent the speed of advancement from rising to an undesirable extend in that at least one clamping element momentarily adheres to the pipe wall and moves relative to the braking means.
This movement is kinematically transmitted to a hydraulic displacer which generates a secondary stream of liquid which is braked through at least one throttle and thus determines the speed between shield and pipe wall.
