摘要： An apparatus for injecting fuel into an internal combustion engine having a fuel injector acted on with highly pressurized fuel actuated by means of a metering valve device that is able to control the pressure in a pressure booster control chamber so that in a pressure booster pressure chamber delimited by a pressure booster piston which can be filled via a check valve with high-pressure fuel and communicates with an injection valve member pressure chamber, the pressure booster piston increases the pressure, causing an injection valve member for injecting fuel to open. To assure a correct injection quantity even if an abrupt pressure drop occurs in the high-pressure fuel source, the pressure booster piston is situated and designed so that if a pressure drop occurs in the high-pressure fuel source, then starting from its neutral position, the pressure booster piston has the capacity to execute a pressure compensation movement by means of which the pressure in the pressure booster pressure chamber is adapted to the pressure of the high-pressure fuel source.

摘要： The invention relates to a fuel injector comprising an injector housing having a pressure chamber from which fuel subjected to a high pressure is injected into a combustion chamber of an internal combustion engine when the pressure in a control chamber expands into a pressure relief chamber by a control valve device. The aim of the invention is to create a fuel injector which has a long service life even though subjected to high pressures. To this end, the injector includes a low-pressure supply line which is connected to a low-pressure return line by a purge path extending through the pressure relief chamber.

摘要： A fuel injector is supplied with fuel under pressure via a high-pressure source and has direct control of an injection valve member by a piezoelectric actuator via a hydraulic booster. The injection valve member of the fuel injector furthermore has a double seat and the injection valve member is provided with two sealing seats which subdivide a nozzle chamber of the fuel injector into three subchambers. When the injection valve member is closed, a first subchamber and a third are in fluidic communication with one another and are supplied with fuel. The second subchamber, which is in communication with injection openings, is conversely fluidically decoupled from the subchambers by the sealing seats. This proposed disposition, with a combination of direct needle control and a double seat of the injection valve member has the advantage that unthrottling of the fuel injector occurs at a very short injection valve member stroke. As a result, even short piezoelectric actuators can in particular be used.

摘要： A fuel injection system for an internal combustion engine including a fuel injector which can be subjected to fuel at high pressure and is actuatable via a metering valve device by which the pressure in a pressure booster control chamber is controllable such that the pressure in a pressure booster pressure chamber, defined by a pressure booster piston, that can be filled with fuel from the high-pressure fuel source via a filling path in which a check valve is disposed and that is in communication with an injection valve member pressure chamber, is increased by the pressure booster piston such that an injection valve member opens for injecting fuel, whereupon fuel is positively displaced out of a damping chamber via a damping path, in which a damping throttle is disposed. To assure stable injection performance, the damping path is embodied such and connected in such a way to the filling path that the fuel positively displaced from the damping chamber via the damping throttle in an injection event reaches the filling path of the pressure booster pressure chamber via the damping path.

摘要： A fuel injector with a pressure booster supplied with fuel at high pressure. A work chamber of the pressure booster is separated from a differential pressure chamber via a booster piston. The pressure relief and the subjection to pressure of the differential pressure chamber are effected via a switching valve which communicates with the differential pressure chamber via a control line. A pressure chamber on an injection valve member communicates with a compression chamber of the pressure booster via a pressure chamber supply line. The switching valve is embodied as a direct-switching 3/2-way valve, whose valve needle is pressure-balanced and has both a sliding seat and a slide seal.
