摘要： The invention relates to a quantity control valve for a fuel injection system, used in internal combustion engines, which includes a longitudinal slide that is movable in a valve housing between a first and a second control chamber and that allocates the fuel, flowing in from at least one low-pressure pump, to at least one high-pressure pump. For driving the longitudinal slide, the inflowing fuel is delivered into the first control chamber via a throttle or baffle valve, past the longitudinal slide. In the second control chamber, there is either a restoring spring that urges the longitudinal slide in the direction of its closing position, or the longitudinal slide there has an effective face-end surface area upstream of which a control line containing a throttle valve ends; this end face is smaller in surface area than the effective surface area of the face end in the first control chamber. In the closing position, the longitudinal slide blocks off the outlet bore with one of its cylindrical guide portions, while with regard to the inlet bore it has a narrowed region, which opposite the longitudinal slide bore leaves a flow cross section open that changes gradually to zero in the direction of the guide portion. In the valve, the flow of fuel is controlled by a targeted manipulation of a cross section via a long slide stroke.

摘要： The invention relates to a fuel pump assembly having a low-pressure region (ND) with at least one low-pressure pump-and a high-pressure region (HD) with at least one regulated-quantity high-pressure pump, which pumps a quantity of fuel required to compensate for the quantitative balance in the high-pressure region, the quantity regulation being effected via a metering unit which is disposed between the low-pressure pump and the high-pressure pump. In order, by simple and sturdy means with high availability and a long service life, to prevent the fuel quantity in correctly pumped by the metering unit at certain operating points from reaching the high-pressure region, the invention proposes that the pumping flow of the low-pressure pump is greater than the pumping flow of the high-pressure pump; that a fuel return line branches off between the metering unit and the high-pressure pump and discharges into the inlet of the low-pressure pump; and that a control element is disposed in the return line.

摘要： A fuel injection system for internal combustion engines, having a high-pressure pump, whose pump work chamber can be made to communicate on the intake side with a fuel tank via a supply line and on the compression side with a common rail via a high-pressure line, from which common rail a plurality of injection lines lead away to the individual injection valves, and having one pressure valve each in the supply line and the high-pressure line, by way of which a return flow of fuel out of the pump work chamber into the supply line and out of the high-pressure line into the pump work chamber is prevented. The pressure valve of the supply line and the pressure valve of the high-pressure line are disposed in a common valve combination.

摘要： A quantity regulation valve for controlling liquids in which a valve member can be moved by an electromagnet, permitting different through flow cross sections to be set so that a high pressure pump that is supplied with fuel via the quantity regulation valve can feed a variable quantity of high pressure fuel. At the same time, the valve member of the quantity regulation valve is equipped with a sealing face that cooperates with a valve seat for the purpose of absolutely preventing the high pressure fuel delivery.
