摘要： 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.

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： The invention relates to a fuel injection valve for internal combustion engines, having a valve body, in which a pressure chamber is configured. A valve needle is disposed in the pressure chamber in a longitudinally displaceable manner. The valve body has a valve seat which interacts with a sealing surface configured on the valve needle. The valve seat delimits the pressure chamber, thus enabling or interrupting a fuel flow to at least one injection opening by the interaction of the valve needle with the valve seat. To this end, the fuel flow to the injection openings occurs between the valve needle and the wall of the pressure chamber, through a sharp-edged gap throttle which is formed between the valve needle and the wall of the pressure chamber.
