Title:
CLOSURE PREVENTIVE DEVICE FOR WATER JET PROPULSION TYPE OUTBOARD MOTOR
Document Type and Number:
WIPO Patent Application WO/1999/019209
Kind Code:
A1
Abstract:
A closure preventive device for water jet propulsion type outboard motors, in which a screen (6) is turnably supported to move between a close position where it covers a suction port (7) and an open position where it is away from the suction port (7) downward. A spring (22) biases the screen (6) toward the close position via an actuation shaft (17). An engagement projection (21) is provided on the actuation shaft (17). While an engagement end (20a) moves from a first position to a second position, it engages with and pushes the engagement projection (21) to move the screen (6) to the open position. When the engagement end (20a) moves beyond the second position, the engagement projection (21) disengages from the engagement end (20a) to permit the spring (22) to return the screen (6) from the open position to the close position. Another closure preventive device comprises a movable blade (8b) and a stationary blade (10a).
