Title:
WATER JET PROPULSION SYSTEM
Document Type and Number:
Japanese Patent JP2965051
Kind Code:
B2
Abstract:
PURPOSE: To continuously maintain stable traveling performance by interposing bar-like members in parallel with an impeller shaft at predetermined intervals at a frame part provided around an inlet port, and by fixing the proceeding side, one end of each bar-like member, to the frame, and by obliquely equipping the other end part of each bar-like member with the other end part faced outwardly against the frame.
CONSTITUTION: An impeller shaft 50 for transmitting turning force is provided toward an exhaust nozzle 57 in a housing 54 having a water inlet port 52 and the exhaust nozzle 57. An impeller 51 is equipped on the outer end part of the impeller shaft 50. A frame 1 is equipped around the inlet port 52. Thin bar-like members 3 are interposed in parallel with the impeller shaft 50 at predetermined intervals at the frame 1 part. The proceeding side. one end part of each bar-like member 3, is fixed to the frame 1. The other end part of each bar-like member 3 is obliquely equipped with the other end part outwardly faced against the frame 1. As the results, stable traveling performance can continuously be maintained.
