摘要： A piezoelectric component with a monolithic stack has piezoceramic layers and electrode layers arranged alternately one on top of the other, at least one porous security layer arranged in the stack for the formation of a crack if mechanical overload of the stack occurs, at least one outer electrode arranged at a lateral surface section for electric contacting of the electrode layers and a plastic sheath of the stack for protecting the stack, wherein the plastic sheath has silicon. The piezoelectric component is characterized in that a coating of the outer electrode, has silicon-free polymer, is arranged between the outer electrode and the plastic sheath. By coating the plating of the outer electrode, the area of the security layer present directly under the plating is protected from silicon component deposits. The piezoelectric component is used for the control of valves, particularly of injection valves of internal combustion engines.

摘要： A method for producing a piezo actuator includes: providing a green stack including alternately successive green films and inner electrode layers; forming trenches on the outside green stack in areas in which the inner electrode layers are intended to be electrically insulated from the corresponding outer electrodes, the trenches shortening the inner electrode layers from the outside of the green stack toward the inside; filling the trenches with an electrically insulating slurry; further processing the green stack, including filling the trenches with slurry, such that the green films produce piezo electric layers and the green stack produces a piezo stack; mounting two outer electrodes on the outside of the piezo stack, such that the two outer electrodes are alternately electrically connected to the inner electrode layers. The trenches may be filled with the slurry using one of the following methods; screen printing, immersion, spraying, or vacuum infiltration.

摘要： A production method for a contact mat for electrical contacting of an actuator uses a contact mat roll including (a) a plurality of terminal posts spaced apart from each other and extending in a first direction and (b) a plurality of electrically-conductive wires extending parallel to each other in a second, perpendicular direction, such that each wire extends across the terminal posts. The method includes unwinding the contact mat roll; connecting the wires to a metallization strip of an actuator; separating the wires at a location between adjacent terminal posts in the mat, such that a contact mat, including a single terminal post and the wires extending from the metallization strip to the terminal post, is connected to the actuator; and winding a free end of the contact mat including the terminal post at least partially around the actuator and securing the terminal post in position.
