<p>PURPOSE:To enable necessary oil to de quickly fed even if any accident happens, by connecting OF cables and firm oil-feeding tanks to each other via switch valves. CONSTITUTION:To OF cables 1, 2, firm oil-feeding tanks 3, 4 are connected via switching-controllable valves 11, 12, and the one-side end sections of the OF cables 1, 2 are connected to an oil feeding device 5 at the time of a leakage oil accident and the other end sections of the OF cables 1, 2 are connected to each other, respectively via valves 6. In a state without leakage oil, the valves 11, 12 are released, and oil pressure in the OF cables 1, 2 is kept respectively and independently by the oil tanks 3, 4. When a leakage oil accident is generated, then by the alarm of oil pressure drop, the valves 11, 12 are closed, and the valves 6 are opened, and the conduction of the OF cables 1, 2 and the oil tanks 3, 4 is interrupted, and the supplementary pressure oil of the oil feeding device 5 at the time of the leakage oil accident may be fed with pressure which can absorbe the transient pressure oil of the reciprocating component of the full length of the OF cables.</p> |
