  • High pressure fuel feeding device for fuel injection engine
    Patent number: 5404858
    Abstract: An outboard motor having an fuel/air injection system wherein all of the major components of the fuel portion of the fuel/air injection system are contained within a sealed chamber having a fuel drain and the conduits that supply fuel to the fuel injectors are also contained within fuel collecting conduits so that any fuel leaking will not escape back to the atmosphere. In addition, the air pressure supplied to the fuel/air injectors is regulated and the air relieved for pressure regulation is returned to an air inlet device having a baffle for condensing any fuel in the regulated air and returning the condensed fuel to a vapor separator. The engine is of the V type and major components of the fuel/air injection system are positioned in the valley between the cylinder banks.

  • Shifting mechanism for outboard drive
    Patent number: 5403218
    Abstract: A shifting mechanism for an outboard drive of a watercraft provides a simple and compact transmission, as well as streamlines a lower unit of the outboard drive to reduce fluidic drag. The shifting mechanism is located on a drive train generally aligned along a vertical axis and above a propulsion shaft of the lower unit. The drive train includes a rotatable input shaft which is driven by a motor. The transmission of the shifting mechanism, which is located above a cavitation plate of the housing of the outboard drive, selectively couples the input shaft and a drive shaft. The drive shaft in turn is coupled to the propulsion shaft. The transmission includes a clutch which is slidably connected to the drive shaft to move along the vertical axis into and out of direct engagement with the input shaft.

  • Jet pump system for a water jet propelled boat
    Patent number: 5401198
    Abstract: A jet pump system for a water jet propelled boat is disclosed that provides for the adjustment of the area of the water intake opening or the water entry angle as a function of the speed of the boat. During low speed operation, the water inlet opening is adjusted to a maximum area, or the water entry angle is adjusted to a maximum angle to enable sufficient water to enter the water duct and permit efficient impeller operation. As the boat speed increases beyond a predetermined speed, the water inlet area is reduced, or the water inlet angle is reduced to prevent excess water from entering the water duct, thereby reducing the drag on the boat.

  • Apparatus for manufacturing a fiber reinforced inorganic hardened body
    Patent number: 5393214
    Abstract: A fiber reinforced inorganic hardened body is manufactured from raw material consisting of a mixture of reinforcing fiber such as bamboo fiber, water-hardening inorganic binder and water by a manufacturing apparatus for stirring and mixing such raw material and forming it into a mat configuration laminated with the thin layers of fine fibers on both the front and rear sides of the thick layer of the normal raw material. The fine fiber material adhered with the water-hardening binder is partially separated from the main raw material at both the material supply side and material discharge side of a set of pin-type rolls. The portion of the fine fiber separated from the main raw material is first supplied to the upstream side of the forming conveyor to form a first layer of fine fiber.
