Title:
ジェット推進艇の冷却システム
Document Type and Number:
Japanese Patent JP3986276
Kind Code:
B2
Abstract:
To provide a cooling system for a jet propulsion boat in which the quantity of washing water consumed can be reduced and the appearance is improved. The cooling system for a jet propulsion boat forces the engine to be cooled and forces the exhaust system to be cooled by taking a part of a jet of water emitted from the jet pump (shown in FIG. 1) into the intake path as cooling water and diverging the cooling water taken into the intake path at the diverging duct in a one-way valve unit to flow into the engine-cooling flow path and the exhaust-system-cooling flow path. The cooling system for a jet propulsion boat is provided with a one-way valve at the midsection of the intake path for enabling cooling water to flow from the intake path to the diverging duct and preventing washing water from flowing from the diverging duct towards the intake path.
