摘要： The fuel injection system having one high-pressure fuel pump and one fuel injection valve for each engine cylinder in which the pump piston defines a work chamber, which communicates with a pressure chamber of the fuel injection valve. A control valve controls connection of the pump work chamber with a relief chamber and having a second control valve controls a connection of a control pressure chamber, which communicates with the pump work chamber defined by a control piston with a relief chamber is controlled, and in which connection a throttle restriction is provided. A flow cross section of the connection of the control pressure chamber with the relief chamber is controlled as a function of the stroke of the control piston, such that with an increasing opening stroke of the injection valve member, a smaller flow cross section is uncovered by the control piston and at the maximum opening stroke of the injection valve member, the uncovered flow cross section is smaller than the flow cross section of the second throttle restriction.

摘要： A fuel injection system for internal combustion engines with a fuel injector that can be supplied from a high-pressure fuel source has an injection valve, with injection nozzles pointing toward the combustion chamber, and coaxial inner and outer nozzle needles assigned to the injection nozzles are triggerable as a function of pressure to open and close various injection cross sections at the injection nozzles. Each of the nozzle needless is assigned a respective damping piston, and the damping pistons are movable relative to one another and act on a damping chamber which can be made to communicate with a low-pressure return system via an outlet throttle. In addition to the damping chamber, a closing chamber is provided, to which an end face of the outer nozzle needle is exposed in the closing direction. The closing chamber can be made to communicate with the low-pressure return system as well, via a closing chamber throttle; the outlet throttle has a greater throttling action than the closing chamber throttle, so that the pressure in the closing chamber drops first, and only after a delay does the pressure in the damping chamber drop as well.

摘要： An oil activated fuel injector which provides a pilot quantity of fuel prior to the main fuel injection event. The oil activated fuel injector includes a delay piston assembly in fluid communication with a high pressure chamber of the fuel injector. The pilot quantity of fuel flows through the delay piston during a pre stroke of the plunger. The oil activated fuel injector reduces engine emissions and noise, and eliminates the need for additional working fluid to be provided therein in order to provide a pilot quantity of fuel.

摘要： The fuel injection system has a fuel injection valve acted upon by the pressure prevailing in a pressure chamber of the fuel injection valve and is movable by this pressure, counter to the force of a closing spring, in an opening direction to open the at least one injection opening, and fuel is delivered under high pressure to the pressure chamber by a high-pressure fuel pump for a fuel injection. The injection valve member is urged in the closing direction at least indirectly by a variable pressure prevailing in a spring chamber of the fuel injection valve. The spring chamber has a communication with a pressure source, which is controlled by a valve whereby different opening pressures of the fuel injection valve for a preinjection and a main injection of fuel can be attained.

摘要： A device for transmitting a displacement of an actuator to a setting element comprises two pistons that delimit two transmission chambers and a compensation chamber with a housing. The compensation chamber is hydraulically connected to the two transmission chambers. The transmission chambers transmit a displacement of the first piston in order to effect a displacement of the second piston. The compensation chamber serves as a reservoir for the transmission medium with which the transmission chambers are filled. The compensation chamber is delimited by an elastomer ring. The elastomer ring depicts a simple and economical realization with which it is possible to subject the compensation chamber to the action of pressure and to change the volume of the compensation chamber at the same time. In a preferred embodiment, the elastomer ring is externally subjected to the action of a tension force via a pressure ring.
