Abstract
PURPOSE: To improve easiness of ship manipulation by simplifying oil pressure control mechanism utilizing a proportional electro-magnetic relief valve or a proportional electromagnetic directional control valve for controlling an oil pressure device which drives the bowthruster.
CONSTITUTION: Oil pressure pumps 4, 4' driven by an engine 13 supply pressurized oil P, P' to oil pressure motors 5, 5'. Thrust (g) of the bowthruster is made proportional to the set pressure of relief valves 7, 7' installed in the oil pressure circuit, and each relief valve 7, 7' is controlled by controlling respective bent circuit 9, 9' by means of a proportional electromagnetic relief valve 10, 10'. The proportional electromagnetic relief valve 10, 10' is connected to a respective amplifier 17, 17' and a controller 18, 18' of a remote control device 16, and also to an automatic controller 26 of a fixed direction automatic ship steering device 20. The operation of the automatic controller 26 is interlocked with a gyroreceiver 22 connected to a gyrocompass 21.
