    摘要: A low leakage large bore fuel system includes a common rail fluidly connected to at least one of a source of heavy fuel oil and a source of distillate diesel fuel. A plurality of fuel injectors are fluidly connected to the common rail and each include a cooling inlet and a cooling outlet. Each fuel injector also includes an electrical actuator coupled to a direct operated nozzle check valve by a pilot valve member and a control valve member. Fuel leakage is reduced between injection events by equalizing pressures in a pilot control chamber and an intermediate control chamber that are separated by a guide surface of the control valve member. Also, between injection events the pilot valve member blocks a drain outlet from a common rail inlet of the fuel injector.

    摘要: In one aspect, a fuel injector includes an injector body that defines a fuel inlet, a drain outlet and a nozzle outlet. A direct operated check valve is positioned in the injector body and includes a needle valve member with an opening hydraulic surface exposed to fluid pressure in a nozzle supply passage, and a closing hydraulic surface exposed to fluid pressure in a needle control chamber. The needle valve member is movable between a first position at which the nozzle supply passage is blocked to the nozzle outlet, and a second position at which the nozzle supply passage is open to the nozzle outlet. A needle control valve is positioned in the injector body and includes a control valve member movable between a first position at which the needle control chamber is fluidly connected to the drain outlet, and a second position at which the needle control chamber is fluidly blocked to the drain outlet. A solenoid actuator is positioned in the injector body and includes a stator assembly and an armature assembly coupled to the control valve member. One of the stator assembly and the armature assembly includes a non-magnetic insert that moves into and out of contact with another of the stator assembly and the armature assembly at an energized position and a de-energized position, respectively.

    摘要: The present disclosure relates to settler plates for a plate settler. The settler plates generally include a hollow support with a hollow interior to receive clarified liquid from a flow channel between adjacent settler plates. An orifice is formed through the hollow support to direct clarified liquid from the flow channel into the hollow interior. The orifice can be positioned such that clarified liquid can flow upwardly out of the flow channel and downwardly through the orifice into the hollow interior. The hollow support can be integrally formed with the settler plate. For example, the hollow support can be formed by bending a tab extending from an end of the settler plate. The tab can be bent into a hollow support with a cross section that is generally polygonal.

    摘要: A fuel injector for an engine is disclosed. The fuel injector may have a fuel nozzle with at least one injection orifice, and a needle element movable within the fuel nozzle between a first position at which the needle element inhibits fuel flow and a second position at which fuel flow is substantially uninhibited. The fuel injector may also have a control chamber located at a base end of the needle element, a body, and a control valve disposed within the body and movable to selectively drain the control chamber, thereby causing the needle element to move between the first and second positions. The fuel injector may further have an armature disposed within an armature cavity of the body and selectively energized to move the control valve, and a pressure reducer disposed within the body and configured to reduce a pressure of the armature cavity.

    摘要: A common rail fuel injector includes a needle valve member that moves to open and close nozzle outlets for a fuel injection event responsive to pressure in a needle control chamber. Between injection events, the needle control chamber is fluidly connected to the fuel inlet by a first pathway that includes a Z orifice, and fluidly connected to the fuel inlet by a second pathway that includes an F orifice, an intermediate chamber and an A orifice. During an injection event, the needle control chamber is fluidly connected to a drain outlet by a third pathway that includes the A orifice, the intermediate chamber and an E orifice. Different performance characteristics are achieved by adjusting the sizes of the respective of F, A, Z and E orifices.
