Title:
WATER JET PROPULSION BOAT
Document Type and Number:
Japanese Patent JP3971161
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily land at the shore by reversely injecting a jet.
SOLUTION: When reverse buckets 22 (L, R) are oscillated to a blocking position Q by the operation of an operating lever 28, a lid member 24 is closed by link mechanisms 33-37, and the oscillation force in the direction of the blocking position Q is made to work on the reverse buckets 22 (L, R) with the jet pressure (b) working on the lid member 24. When the reverse buckets 22 (L, R) are oscillated to an non-blocking position P by the operation of the operating lever 28, the lid member 24 is opened by the link mechanisms 33-37 and the jet pressure working on the lid member 24 is made to escape.
