    摘要: An arrangement is proposed for forming a piezoelectric actuator, which has at least one piezoelectric element that in each case consists of a multi-layer structure of piezoelectric-layers, wherein internal electrodes arranged between the piezoelectric-layers in the direction of the build-up of the layers of the piezoelectric element, have an electrical voltage of different polarity alternately applied to them. Around the piezoelectric element, or in the case of multiple piezoelectric elements positioned in series in the activation direction, around the piezoelectric elements, and at least partially around the actuator head and the actuator foot there is arranged a covering system made from at least one layer of an insulating material. The at least one layer encloses the joints between the piezoelectric element or elements and the actuator head and the actuator foot, forming a seal.

    摘要: A fuel injection valve with a valve body in which a valve needle that has a longitudinal axis can slide in the longitudinal direction in a bore. The combustion chamber end of the bore is provided with a conical valve seat between the valve needle and the wall of the bore a pressure chamber is formed, which can be filled with fuel and extends to the valve seat. The valve needle has a valve sealing surface that cooperates with the valve seat in order to control at least one injection opening leading from the valve seat and contains an annular groove that extends in a radial plane of the valve needle. The downstream edge of the annular groove is embodied as a sealing edge and is hydraulically connected to the pressure chamber on a continuous basis.
