PURPOSE:To obtain an all-weather type radio-controlled unmanned working ship immediately recovering even if the ship is abruptly inclined (tumbled) and capable of continuing the suction and exhaustion of an engine by connecting a suction pipe and an exhaust pipe with a shuttle valve respectively to the suction pipe and exhaust pipe of the engine. CONSTITUTION:An air filter 15 is fitted to the suction manifold 14 of an engine 2 installed at the center of a hull 1 and is connected to a suction pipe 17 with a shuttle valve via a suction L-pipe 16. On the other hand, an exhaust manifold 18 is connected to an exhaust pipe 20 with a shuttle valve via an exhaust L-pipe 19. When the inclination of the hull 1 becomes a certain inclination angle or more, the check valve 53 of shuttle valves 17, 20 at suction and exhaust pipe ends overcomes the tension of a spring 51 and prevents the sea water from infiltrating, and the suction and exhaustion is continued through a check valve 53' on the opposite side. The sea water having infiltrated when the check valves 53, 53' are opened or closed is discharged through a hose nipple 41. Accordingly, the engine is not stopped while a ship is tumbled and recovered. |
