A VACUUM FLUID TRANSFER SYSTEM TRANSFERS A FLUID BY SETTING INSIDE OF A MAIN PIPE LINE (10) TO VACUUM AND USING A PRESSURE DIFFERENCE. THE SYSTEM INCLUDES A PORTION WHERE THE MAIN PIPE LINE (10) IS HORIZONTALLY ARRANGED, AND IS PROVIDED WITH AN AUTOMATIC INTAKE VALVE (17) AND A TERMINAL AUTOMATIC INTAKE VALUE (16) FOR INTRODUCING ATMOSPHERE INTO THE MAIN PIPE LINE (10) FROM THE OUTSIDE OF THE MAIN PIPE LINE (10) WHEN A DEGREE OF VACUUM INSIDE THE MAIN PIPE LINE (10) IS REDUCED TO A PREDETERMINED VALUE OR LOWER. |
