摘要： The invention relates to a system for injecting fuel into a combustion chamber of an internal combustion engine, having a fuel injector, which can be subjected to fuel at high pressure and which is actuatable via a metering valve, by which the pressure in an injection valve member control chamber or in a control line is controllable such that an injection valve member opens and closes for injecting fuel. The injection valve member control chamber can be evacuated via an outlet throttle device into a control line which has a smaller throttle cross section than an inlet throttle device, by way of which the injection valve member control chamber can be filled.

摘要： A fuel injection device for an internal combustion engine includes a housing and a valve element which is arranged in the housing. The valve element interacts, in the region of a fuel outlet opening, with a valve seat. The valve element is embodied by at least one first part and at least one second part which are coupled to one another by means of a hydraulic coupler. The hydraulic coupler has a coupling chamber which is delimited at least partially by a sleeve which is guided on the first part of the valve element. Additionally a guide element guides an end region of the first part of the valve element, which end region being oriented toward the second part of the valve element.

摘要： The invention relates to a pressure boosting system for at least one fuel injector of a high pressure injection system of an internal combustion engine, having a hydraulic pressure booster that is actuated by a control valve. The hydraulic pressure booster is configured with a pressure boosting piston, which comprises a first pressure booster piston part having a first diameter and a second pressure booster piston part having a second diameter, wherein the first diameter is greater than the second diameter. The pressure booster piston is disposed within a hydraulic reservoir chamber, onto which pressure is applied, together with the first pressure booster piston part having the greater diameter, wherein the accumulator chamber in turn is configured within a base body. The base body has a piston guide body for at least one of the pressure booster piston parts. The piston guide body is at least partially surrounded by an annular space, which is part of the hydraulic accumulator chamber.
