摘要： A fuel injection system for an internal-combustion diesel engine has a fuel injector, typically one of several, supplied by way of a high-pressure fuel line with highly pressurized fuel for the injection of the fuel into the combustion space of the internal-combustion engine during an injection operation. A pressure control valve connected in front of the fuel injector in the high-pressure fuel line is provided for controlling the pressure of the fuel injected during the injection operation. The pressure control valve contains a freely displaceable piston operating on both sides and a slide connected into the flow path of the high-pressure fuel line for the opening and closing of the passage cross-section of the flow path of the high-pressure fuel line as a function of the position of the piston. On the forward side of the piston, a first pressure space is provided which acts upon the piston in the opening direction of the slide, and, on the rearward side of the piston, a second pressure space is provided which acts upon the piston in the closing direction of the slide. An adjusting valve is used for adjusting the pressures in the first and/or second pressure space in the sense of a displacement of the piston in the opening or closing position. The fuel injection system according to the invention permits a proportional controlling of the fuel injection pressure during the injection operation over a wide adjusting range.

摘要： An injection nozzle for use in a common-rail system includes a nozzle body with an actuator piston. In the closed condition of the nozzle the nozzle body bears against a seat and upstream of the seat delimits a nozzle chamber communicated with the high-pressure line of the common-rail system. A working chamber of the actuator piston is communicated with the high-pressure line by way of a feed throttle means, the active surface area of the actuator piston being larger than the surface area of the nozzle body which is effective in the nozzle chamber. A return line leads from the working chamber through a return valve. An actuating means is operated by an electrical signal for actuating the valve member of the return valve. The actuating means is a means which displaces the return valve member in analog relationship with the electrical signal so that the return valve forms in the return line a throttle of variable cross-section.

摘要： A servo valve for an injection nozzle includes a housing having a valve chamber, a high-pressure opening, a connecting opening and a return opening. The valve chamber movably accommodates a valve member which can be displaced by actuating means to bear selectively against a first seat and a second seat. The valve member, when bearing against the first seat, closes the return opening and connects the high-pressure opening to the connecting opening. When bearing against the second seat it closes the high-pressure opening and connects the connecting opening to the return opening. The connecting opening is connected to a working chamber of the injection nozzle whose nozzle is closed when the working chamber is subjected to high pressure and opens upon a drop in pressure in the working chamber. The actuating means includes a component which varies in length when electrically actuated and which is connected to the valve member through the return opening by way of an actuating member.
