초록 ▼

A pumping system for a fuel injection system includes a body defining a high pressure pumping chamber, a plunger, a high pressure outlet, a high pressure fluid line connecting the pumping chamber to the outlet, a control valve along the fluid line, and a valve and restriction arrangement along the fluid line. The valve and restriction arrangement includes a restriction and a valve body. The valve body is movable between an open position in which fuel flow from the pumping chamber is generally unrestricted by the restriction and a closed position in which fuel flow from the pumping chamber is significantly restricted by the restriction to store energy in the pumping chamber. Advantageously, the high pressure restriction concept may be utilized in a pumping system for various types of rate shaping, including boot injection and square injection, in addition to pilot operation and post injection operations, and others.

대표청구항 ▼

1. A pump system for a fuel injection system, the pump system comprising:a body defining a high pressure pumping chamber; a plunger disposed in the pumping chamber for pressurizing fuel; an outlet; a fluid line connecting the pumping chamber to the outlet; a control valve along the fluid line, the control valve including a first valve body movable between a closed position in which pressurized fuel is routed from pumping chamber to the outlet and an open position in which pressure relief is provided to the fluid line; and a valve and restriction arrangement along the fluid line, including a restriction and a second valve body, the second valve body being movable between an open position in which fuel flow from the pumping chamber is generally unrestricted by the restriction and a closed position in which fuel flow from the pumping chamber is significantly restricted by the restriction to store energy in the pumping chamber.
