摘要： 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 (40) for receiving a fluid, a control valve (30), a flow passage (46), and an insert (33)-. 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.
