Title:
COOLING DEVICE FOR VESSEL PROPELLER
Document Type and Number:
Japanese Patent JP2023102498
Kind Code:
A
Abstract:
To sufficiently secure the collecting ability for fine matter even when not using a valve for opening and closing a bypass passage.SOLUTION: A cooling device for an outboard engine has an upstream part 27A of a drain passage, a downstream part 27B of the drain passage, a collection passage 32 provided with a collector 33, and a bypass passage 34 arranged to have a difference between a flowing direction of cooling water flowing into a branch part 35 from the upstream part 27A and a flowing direction of the cooling water flowing into the collection passage 32 from the branch part 35 to be smaller than a difference between the flowing direction of the cooling water flowing into the branch part 35 from the upstream part 27A and the flowing direction of the cooling water flowing into the bypass passage 34 from the branch part 35, and a difference between the flowing direction of the cooling water flowing into a confluent part 36 from the bypass passage 34 and the flowing direction of the cooling water flowing into the downstream part 27B from the confluent part 36 to be smaller than the difference between the flowing direction of the cooling water flowing into the confluent part 36 from the collection passage 32 and the flowing direction of the cooling water flowing into the downstream part 27B from the confluent part 36.SELECTED DRAWING: Figure 5
