Abstract:
Control shutter assembly for a water fountain comprising:a fountain nozzle having means to discharge a pressurized steam of water; a shutter located adjacent said nozzle which prevents or allows said stream to exit; said shutter integrally connect to a rotatable shaft; an armature having a tip comprised of magnetic material at one end and at the other end affixed to the said rotatable shaft, whereby the opening and closing of said shutter is controlled by said armature; a fixed stop located adjacent a blocking position of said armature; at least two, first and second electromagnets having magnetic cores mounted adjacent said armature tip; said armature tip positioned in close proximity said electromagnets such as in a first position said armature stays positioned against said stop whenever said first electromagnet remains activated, and said shutter continues to block said exit port and no water is discharged; and whereby by de-activating said first electromagnet and activating said second electromagnet, said armature is made to rotate said shaft and said shutter will rotate so that it is no longer blocking said exit orifice, and said stream will traverse through said exit aperture, and whereby in order to stop the flow said first electromagnet is energized and said second electromagnet is de-energized to move the armature in the direction of said stop to return said armature and said shutter to said first position.
