    摘要: A control system for a fuel injector is disclosed. The control system has a nozzle member with at least one orifice, and a needle check valve. The needle check valve is recipratingly disposed to open and close the at least one orifice. The control system also has a control chamber located at the base end of the needle check valve, and a control valve movable to selectively drain and fill the control chamber. The control system further has an injector body, a first piston located within the injector body, and a second piston located within the injector body. The first piston is operatively connected to the control valve to move the control valve. The second piston is located a distance from the first piston to form a coupling chamber. The control system additionally has a partial-ball check valve associated with the coupling chamber to selectively replenish the coupling chamber.

    摘要: A fuel system for a work machine is disclosed. The fuel system has a fuel injector, a first source of fuel at a first pressure, a second source of fuel at a second pressure, and a pressure control device. The pressure control device is disposed between the fuel injector and the first and second sources. The pressure control device is configured to selectively direct the fuel at the first pressure and the fuel at the second pressure to the fuel injector.

    摘要: A fuel injector for a work machine is disclosed. The fuel injector has nozzle member having at least one orifice and a needle valve element having a tip end. The needle valve element is axially movable to selectively allow and block fuel flow through the at least one orifice with the tip end. The fuel injector also has at least one supply passageway in communication with the tip end of the needle valve and a variable restrictive device disposed within the at least one supply passageway.

    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 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.

    摘要: A fuel injector for a machine is disclosed. The fuel injector has a nozzle member with a first end and a second end. The first end of the fuel injector has at least one orifice. The fuel injector also has a control chamber located at the second end of the nozzle member with an end wall portion approximately orthogonal to an axial direction of the nozzle member. The fuel injector further has a port disposed in the end wall portion of the control chamber and at least one passageway in fluid communication with the control chamber via the port. The fuel injector additionally has a needle valve element with a tip end and a base end. The tip end is configured to selectively block fuel flow through the at least one orifice. The base end has a recess configured to cap off the port.
