摘要： A fuel injection for internal combustion engines, having a valve member which is guided so that it moves axially in a valve body and uses a sealing face provided on a combustion chamber end to open and close an injection opening on the valve body. A piezoelectric actuator includes a piezoelectric stack, which changes in length with the action of a control voltage, is coupled to the combustion chamber end of the valve member to actuate the valve member. In order to prevent an interference with a precise adjustment motion of the valve member of an unwanted length change in the piezoelectric stack, a clamping device is provided which fixes the end of the piezoelectric stack remote from the valve member in its axial position during the injection phase of the fuel injection valve, and permits an axial compensation for play at the piezoelectric stack during an injection pause.

摘要： A fuel injector for injecting fuel into an internal combustion engine has an at least two-stage pressure boosting or a variable pressure boosting and an actuator able to actuate an injection valve member. A prestroke element travels a prestroke distance hv during the opening movement of the injection valve member until it reaches a changeover point of the pressure boosting. The injection valve member or a second piston is associated with a prestressing spring element, which can be a disk spring, a tubular spring, a helical spring, or a spring element integrated into the second piston. During the passage through the prestroke distance hv, the prestressing spring element continuously builds up the force required to switch the pressure boosting from a first opening pressure po,1 to a second opening pressure Po,2.
