    摘要: A fuel injector, in particular a fuel injector for fuel injection systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator, a valve closing element that can be actuated by the actuator and that works together with a valve seat face to form a seal seat, and a temperature compensation device. The temperature compensation device has a housing that is elastically deformable along a direction of actuation of the actuator, and has at least one throttle that connects an interior space of the housing with a fuel inlet of the fuel injector. The cross-section of this throttle is dimensioned such that an entry and exit of fuel into the housing of the temperature compensation device is enabled when there is a temperature-caused change in length of components of the fuel injector.

    摘要: An actuator (1), in particular for operation of fuel injectors in fuel injection systems of internal combustion engines, has in this embodiment a plurality of layers (2) of a piezoelectric or magnetostrictive material arranged in a stack. The actuator (1) is prestressed by a tie rod (6) arranged in a central recess (5) by way of opposing threads (7 and 8). Securing the device and the transfer of force are accomplished by a cover plate (3) and a bottom plate (4). The prestress can also be created by a sheathing (9) surrounding the actuator (1), which transfers an axial force component onto the layers (2) via the cover plate (3) and the bottom plate (4) by flanging of projecting ends (10).
