Patent 7980483 was granted and assigned to Eaton Corporation on July, 2011 by the United States Patent and Trademark Office.
An injector for an injection system is provided, including a first opening, a second opening, an open position and a closed position. The first opening is for spraying the fluid out of the injector, and the second opening is for allowing the fluid to exit the injector. When the injector is in the open position, the injector sprays the fluid from the first opening and the flow of the fluid to the second opening is substantially blocked. When the injector is in the closed position the injector allows the fluid to exit the injector from the second opening. The injector substantially blocks the spray of the fluid from the first opening when the injector is in the closed position.
