Abstract
A marine cooling system performs a temperature adjustment of an object to be cooled such as an internal combustion engine of a marine vessel. The marine cooling system includes a water supply flow passage to supply cooling water to the object, a water drain flow passage to drain the cooling water from the object to reduce an amount of the cooling water that contacts the object, and a flow passage controller to shut off the water to the drain flow passage.
Claims14
A marine cooling system to cool an object in a marine vessel, the marine cooling system comprising:
- a water supply flow passage to supply cooling water to the object;
- a water drain flow passage to drain the cooling water from the object;
- and
- a flow passage controller located within the water drain flow passage and configured to close the water drain flow passage;
- wherein
- when the marine vessel is sailing, the cooling water is supplied to the flow passage controller from a first side of the flow passage controller opposite to a second side of the flow passage controller, the second side of the flow passage controller being connected to a portion of the water drain flow passage that is connected to and drains the cooling water from the object.
A marine vessel comprising:
- a marine cooling system to cool an object, the marine cooling system including:
- a water supply flow passage to supply cooling water to the object;
- a water drain flow passage to drain the cooling water from the object;
- and
- a flow passage controller located within the water drain flow passage and configured to close the water drain flow passage;
- wherein
- when the marine vessel is sailing, the cooling water is supplied to the flow passage controller from a first side of the flow passage controller opposite to a second side of the flow passage controller, the second side of the flow passage controller being connected to a portion of the water drain flow passage that is connected to and drains the cooling water from the object.
A marine propulsion device comprising:
- a marine cooling system to cool an object, the marine cooling system including:
- a water supply flow passage to supply cooling water to the object;
