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.

摘要： The invention relates to a pressure booster arrangement for high-pressure injection systems or high-pressure injection system parts of internal combustion engines. A differential piston which operates with a large cross section in a medium-pressure reservoir and with partial cross sections is operative in terms of positive displacement in associated control and work pressure chambers that are separate from the medium-pressure reservoir and that are disposed in a guide body. The guide body guides the differential piston in its strokes and in turn axially adjoins a valve body. The valve body receives control and check valves for controlling communicating lines of the guide body and of the valve body for controllably connecting the control and work chambers to the medium-pressure reservoir or to a relatively pressureless fluid reservoir. It is essential to the invention that the valve body and the guide body separate from it, which at least on its end remote from the valve body is acted upon by the pressure in the medium-pressure reservoir, adjoin one another axially with end faces facing toward one another. Between these end faces, a spacer chamber or hollow chamber communicating with the relatively pressureless reservoir is embodied.

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.
