ABSTRACT:
A device for flushing out contaminants from a line section conveying a pressurized fluid, includes a container for receiving the contaminants, and a valve assembly connecting the container to the end of the line section to be flushed. The valve assembly is effective when the line section is depressurized to connect the interior of the container to the interior of the line section so that the container receives the contaminants and pressure in the line section immediately upon the application of pressurized fluid to the line section, and is effective immediately after pressurized fluid has been applied to the line section, to disconnect the interior of the container from the line section and to connect the container to the atmosphere to thereby discharge its contents to the atmosphere.
