Patent number: 4651687Abstract: An automatic compression releasing device intended for reducing the pressure inside the combustion chamber of the four cycle engine at the start by opening and closing the intake or exhaust valve of the combustion chamber actuated by the cam on the cam shaft through the tappet. A single moving piece mounted, on the side of the gear integrated with the cam shaft, as enclosing the cam shaft, can slide over the side of the gear in a given direction, guided by two slots opened in the moving piece and two pins planted on the gear side. A tappet lifting arm is extended from the moving piece to such a position as to push up the tappet. At the start, the centrifugal force on the moving piece is designed not to exceed the opposing force, thus keeping the tappet lifting arm projected out of the cam base circle, and also retaining the returning force of the moving piece acting on the tappet lifting arm through the tappet being supported by the guide slots and pins.Type: GrantFiled: December 20, 1985Date of Patent: March 24, 1987Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Masanobu Yamashita, Hiroshi Takada, Takemi Inoue, Suguru Yamauchi

Patent number: 4541808Abstract: A water jet propulsion system for watercraft having an impeller, especially a conical oblique flow impeller with an increased outer diameter in going toward the downstream side. The impeller is secured to a transmission shaft which is journalled by bearings in a hub of fixed blades and formed at its end portion with spline grooves being able to fit in spline strips formed at the forward end portion of a drive shaft. This allows a pump portion of the water jet propulsion system to be assembled outside the watercraft and separately therefrom, so that positioning of the impeller with respect to its duct can be effected with a high degree of accuracy.Type: GrantFiled: December 18, 1981Date of Patent: September 17, 1985Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Hiromi Ono, Takemi Inoue

Patent number: 4320713Abstract: A small watercraft having a float on either side of its hull pivotally connected thereto for rotation about a shaft mounted parallel to the direction of movement of the watercraft between a horizontal operative position and a vertical inoperative position taken when the watercraft is stowed away. The floats can be locked in these two positions and in any position as desired between these two positions. Each float is substantially triangular in planar configuration and diverges in going toward the stern of the watercraft. When the watercraft is stationary on the water, the forward end of each float is exposed from the surface of the water; and when the watercraft is planing, each float is exposed in its entirety on the surface of the water.Type: GrantFiled: May 8, 1980Date of Patent: March 23, 1982Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Hiroshi Nishida, Keiichi Nakamizo, Takemi Inoue, Takeshi Miyazaki
