    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 is proposed, in which with the aid of a high-pressure pump fuel is pumped at high pressure into a high-pressure fuel reservoir (6), from which electrically controlled fuel injection valves (9) are supplied. The pressure in the high-pressure fuel reservoir is maintained in such a way that a first pump element (16) pumps fuel into the high-pressure reservoir with a variable pumping quantity, and a second pump element (17) as needed pumps a constant high-pressure fuel quantity into the high-pressure reservoir. A simple, economical system is thus obtained for furnishing high fuel pressure for injection by the fuel injection system (FIG. 2).

    摘要： A piston pump of the roller tappet type for high-pressure fuel delivery in fuel injection systems of internal combustion engines, particularly in common rail injection systems. A drive shaft that is supported in the pump housing and has a number of cam-like projections in the circumference direction. At least one tappet that is disposed in a cylinder chamber radially with regard to the drive shaft and in its radially inner end region has a rotatable roller which is supported so that it can roll in the circumference direction against the drive shaft in the region of its projections in order to reduce the wear in the region of the roller bearing. The pump is embodied so that a lubricant supply opening that leads from the circumference of the tappet and feeds into the radially inner tappet end region supporting the roller and at least during a part of the stroke, communicates with a lubricant supply line of the housing, which line feeds into the cylinder chamber.

    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： A device for controlling gas exchange valves of an internal combustion engine, which has hydraulic valve positioners, each having a positioning piston acting on the gas exchange valve and two hydraulic working chambers, delimited by the positioning piston, of which the first working chamber, for closing the gas exchange valve, is continuously filled under fluid pressure and the second working chamber, for opening the gas exchange valve, is alternately filled and emptied with pressurized fluid via a first and second electrical control valve. To reduce the number of control valves, which may be necessary, for a valve pair, the filling of the second working chamber of the second valve positioner is performed via the second working chamber of the first valve positioner, which is connected to the first control valve, after a predetermined stroke of the positioning piston of the first valve positioner to open the assigned gas exchange valve.

    摘要： A device for controlling an opening cross section in the combustion cylinder of an internal combustion engine is provided, the device having a gas exchange valve integrated into the combustion cylinder and having an actuator which drives the valve element to execute a closing stroke and an opening stroke. A valve brake which is active during a residual closing stroke of the valve element is provided for the purpose of reducing the impact velocity of the valve closure member of the valve element on the valve seat in the closing stroke of the valve element. The valve brake has a hydraulic damping element with a fluid displacement volume which flows out through a throttle cross section of a throttle opening, and a control unit for controlling the throttle cross section as a function of the viscosity of the displacement volume.
