    Abstract: A fuel injector includes an injector body comprising an internal injector cavity, a flow passageway, and a drain conduit. The flow passageway is in fluid communication with at least one injector orifice. The fuel injector further includes a valve assembly comprising a valve seat and a valve member in fluid communication with the fuel circuit. The valve member is configured to move between an open position allowing fuel flow through the at least one injector orifice and a closed position inhibiting fuel flow through the at least one injector orifice. The fuel injector also includes a nozzle valve element fluidly coupled to the valve assembly, an actuator operably coupled to the valve assembly and the nozzle valve element, and a flexible member configured to elastically deform in response to pressure in the fuel injector. The flexible member is configured to inhibit flow to the drain circuit during an injection event.

    Abstract: A fuel injector includes an injection control valve having a stator core that is electrically isolated from surrounding parts such as a stator housing. The stator core includes a first annulated wall having an inner surface, a second annulated wall having an outer surface, a radially extending wall connecting the first and second annulated wall, and a radially extending slot extending through the first annulated wall, the radially extending wall, and the second annulated wall. The stator core may include a limited number of contact points with the stator housing. Alternatively or additionally, an electrically insulating material may be placed between the stator core and the stator housing.

    Abstract: A method for operating an engine fueling system to manage fuel in an accumulator supplying fuel to an engine including multiple cylinders comprising monitoring fuel load in the accumulator, determining that the engine is operating in a cylinder deactivation mode such as a skip-fire mode during which one or more fueling events to one or more of the cylinders is being skipped, and controlling a supply of fuel from a fuel pump to the accumulator during the cylinder deactivation mode operation. In embodiments, controlling the supply of fuel includes causing fuel to be supplied from the fuel pump to the accumulator if the monitored fuel load is less than or equal to a first fuel load, and causing fuel to be not supplied from the fuel pump to the accumulator if the monitored fuel load is greater than the first load value. Controlling the supply of fuel may comprise controlling the supply of fuel during each fueling event cycle of each deactivated cylinder.

    Abstract: A pump inlet valve includes a valve body and a plunger assembly. The valve body includes a valve body cavity. The plunger assembly is arranged within the valve body cavity and includes a plunger body, a plunger barrel formed at the plunger body so as to form a plunger barrel volume, and a plunger. The plunger is configured to move within the plunger barrel to thereby allow a fluid to flow past the plunger assembly when the plunger is in an open position and to inhibit the fluid from flowing past the plunger assembly when the plunger is in a closed position. The plunger is configured to allow continuous fluid communication between the plunger barrel volume and a supply inlet, through which fluid is supplied to the pump inlet valve.
