Title:
【発明の名称】原動機と可変ピツチプロペラとを有する舟艇駆動装置用の制御装置
Document Type and Number:
Japanese Patent JP3175770
Kind Code:
B2
Abstract:
A variable-speed propeller in a ship drive has the hydraulic valves feeding the working chambers of the hydraulic drive for the variable-speed propeller formed as electromagnetic valves controlled by timing relays which can be switched by a rocker switch or push-button switches to adjust the propeller pitch by an angular increment controlled by the "on" time of the relays. The engine speed is detected and, when the engine speed exceeds the maximum speed of the engine, the relay associated with increased pitch is triggered to obtain an increment of engine-speed reduction, thereby preventing the system from inadvertently having the blade pitch reduced when the engine is at maximum speed.
