    摘要: A fuel injection apparatus having a fuel supply pump supplying fuel to a high-pressure pump which delivers fuel into a reservoir with a metering device for adjusting the fuel quantity delivered into the reservoir; the metering device has a control valve triggered by an actuator. The control valve has a valve element guided in a cylinder of a valve housing can be slid by the actuator in opposition to a spring and in cooperation with an opening in the cylinder bore connected to an inlet from the supply pump or an outlet to the high-pressure pump, controls a flow cross section from the supply pump to the high-pressure pump. The valve element can close the flow cross section at least almost completely and also control a connection of the inlet from the supply pump or of the outlet to the high-pressure pump to a discharge region, and open this connection when it closes the flow cross section.

    摘要: A high-pressure pump for a fuel injection system of an internal combustion engine, having a housing at least one pump element having a pump piston located in the housing and driven in a reciprocating motion via a transmission element by a drive shaft supported rotatably in the housing via at least one bearing point. The drive shaft has an eccentric portion on which the transmission element is rotatably supported via a bearing point. Fuel for lubrication is delivered to the bearing point of the transmission element in the eccentric portion of the drive shaft via a conduit system extending through the drive shaft.

    摘要: The fuel injection system has a high-pressure pump which pumps fuel into a reservoir to be supplied to injectors disposed at the engine cylinders. A feed pump supplies fuel to the high-pressure pump. The high-pressure pump has at least one pump element including a pump piston that defines a work chamber and is driven in a reciprocating motion; the work chamber has a communication with the compression side of the feed pump, in which an intake valve opening toward the work chamber is disposed, and through which valve fuel flows into the work chamber upon the intake stroke of the pump piston. The intake valve has a valve member, which is urged in a closing direction by a closing spring, and the closing spring is braced at least indirectly on the pump piston; with an increasing intake stroke of the pump piston, the closing force exerted on the valve member by the closing spring becomes less. A minimal opening differential pressure of the intake valve is less than 0.9 bar.
