<p>PURPOSE:To prevent an oil hammer phenomenon formed when closing a valve at a time of an accident, by connecting a by-path with the valve and a filter between arbitrary two lines. CONSTITUTION:Oil cooling pipe type cables 1a, 1b are mounted in parallel, and valves 14, 17 and filters 13, 16 are connected in parallel with an opening and closing valve 8a at the circulation oil outlet ends of cable lines for forcedly rotating cooling oil in the parallel cables and between the intermediate connecting portions 3a, 3b of both lines. Consequently, the opening and closing valve 8a is automatically closed when there happen accidents in the lines consisting of the pipe 1a, but the valve 14 is automatically opened at the same time, thus as oil hammer phenomenon formed when suddenly closing the opening and closing valve 8a can be prevented. And impulsive oil pressure propagating to an area around the valve 17 can be reduced because the valve 17 on the way of the line is simultaneously opened.</p> |
