Title:
WATER JET PROPULSOR DRIVEN BY INTEGRAL CANNED ELECTRIC MOTOR
Document Type and Number:
Japanese Patent JP3696911
Kind Code:
B2
Abstract:
PURPOSE: To rotate a tubular suction shroud and an impeller to produce a pressurized water flow from an intake end to an outlet end within a housing by providing a stator with energizing means, and providing an impeller assembly or the like in the hollow part of the housing.
CONSTITUTION: A housing 4 has an intake end 10 and an outlet end 12 and an annular stator 14 is provided inside the housing 4. Energizing means 18 for energizing the stator 14 is provided. An impeller assembly 20 including a tubular suction shroud 22 and an impeller 24 is freely rotatably supported within the housing 4. A rotor 26 cooperating with the suction shroud is provided around the suction shroud inside the stator 14. When the stator 14 is energized in this way, the rotor 26 rotates to thereby rotate the impeller 24 to pump water from the intake end 10 to the outlet end 12 of the housing 4. Thus, the water discharged from the outlet end 12 generates thrust which propels a vessel.
