20080296412 | Fuel injector having a flow passage insert - Fuel injectors having control passages with relatively large volumes may have limited responsiveness. The injector described herein may help to reduce the control passage volume and improve responsiveness by providing a chamber for receiving a fluid, a control valve, a flow passage, and an insert. The control valve may be moveable between a first position and a second position. The flow passage may extend between the control valve and the chamber, and the flow passage may define a first volume. The insert may be located within the flow passage, and the insert may occupy a second volume. The placement of the insert within the flow passage reduces the volume of the flow passage that is available to receive the fluid to a third volume equal to the first volume less the second volume. | 12-04-2008 |
