Abstract: A fuel injection apparatus for injecting fuel into the combustion chambers of an internal combustion engine. includes a high pressure accumulator, a pressure booster, and a metering valve. The pressure booster includes a working chamber and a control chamber that are separated from each other by an axially movable piston. A pressure change in the control chamber produces a pressure change in a compression chamber that acts on a nozzle chamber via a fuel inlet. The nozzle chamber encompasses a nozzle needle. A nozzle spring chamber that acts on the injection valve element can be filled on the high-pressure side via a line that leads from the compression chamber and contains an inlet throttle restriction. On the outlet side, the nozzle spring chamber is connected to a chamber of the pressure booster via a line that contains an outlet throttle restriction.

Abstract: A fuel injection system includes a pressure booster having a displaceable piston which can be subjected to pressure via a pressure booster chamber on the low-pressure side for compressing the fuel in a pressure booster chamber on the high-pressure side to be delivered to an injector. The stroke of the piston is controllable by the pressure in a differential chamber of the pressure booster and is used to vary the fuel pressure delivered to the injector. Means for continuously variable definition of the inlet cross section to the pressure booster chamber of the pressure booster on the low-pressure side or of the outlet cross section from the differential chamber of the pressure booster are provided.

Abstract: A fuel injection system includes a pressure storage chamber and one injector assigned to each cylinder, which injector can be connected to the pressure storage chamber via a pressure line that includes a metering valve. Using a single 2/2-way valve as a metering valve per cylinder makes for a more-economical manufacture of a fuel system, especially for small engines. The fuel injection is done under pressure control.

Abstract: The invention relates to a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine. The fuel injector is in communication with a high-pressure reservoir for fuel and includes a pressure booster. The fuel injector is actuatable via a control valve and has an injection valve member, which is urged in the closing direction by at least one spring element, and associated with the injection valve member is a damping element that is movable independently of it. This damping element defines a damper chamber, and the injection valve member has a first needle part and a second needle part. Associated with the second needle part is a control chamber that can be connected to the system pressure side or the maximum pressure side.

A first actuator can actuate a closing element. The valve body is connected to a holding body that has a nozzle body connected to it, which encompasses an injection valve element. In order to relieve the pressure in the control chamber, an additional, second outlet throttle is provided, whose closing element can be actuated either by an additional actuator or as a function of the power supply to a double-switching actuator.

Abstract: A fuel injection apparatus having a fuel injector fed by a high-pressure fuel source and having an injection valve with injection nozzles associated with coaxial inner and outer nozzle needles can be actuated in a pressure-dependent manner to open and close various injection cross sections at the injection nozzles. A pressure surface of the outer nozzle needle is associated with a closing chamber. To actuate the outer nozzle needle, a first on/off valve can connect the closing chamber to a low-pressure/return system. The inner nozzle needle has a control piston whose pressure surface protrudes into a second control chamber, and a second on/off valve is can connect the control chamber to the low-pressure/return system so that when the second on/off valve is actuated, the pressure is relieved in the second control chamber. This permits a separate actuation of the outer nozzle needle and inner nozzle needle.

Abstract: A pressure booster of a fuel injection system includes a displaceable piston unit (30a, 31a), which on one end can be subjected to pressure via a pressure booster chamber on the low-pressure side and on the other end has a pressure booster chamber on the high-pressure side for fuel compression. The piston unit has a further piston cross section, which is reduced compared to the first piston cross section provided for imposing pressure, for embodying a differential chamber that is connectable to a leak fuel line. At least one control conduit connects the pressure booster chamber on the low-pressure side to the differential chamber, whose opening is closed or opened as a function of the motion of at least parts of the piston unit.
