20100102138 | PIEZOELECTRIC COMPONENT COMPRISING A SECURITY LAYER AND AN INFILTRATION BARRIER AND A METHOD FOR THE PRODUCTION THEREOF - A piezoelectric component with a monolithic stack, has electrode layers and piezoceramic layers arranged alternately one on top of the other, the piezoceramic layers have a piezoceramic, and having at least one porous security layer arranged in the stack for the formation of a crack if mechanical overload of the stack should occur. The piezoelectric component has an infiltration barrier arranged between the security layer and a lateral surface section of the stack for suppressing the penetration of a foreign substance into the security layer. The piezoelectric component can be as a piezoactuator for controlling a valve, particularly a valve of an internal combustion engine. | 04-29-2010 |

20130248623 | Piezoelectric Component with Contact - A piezoelectric component, e.g., for use as an actuator of a fuel injection valve in a motor vehicle, may include a stack-shaped actuator body including a plurality of piezoelectric elements and inner electrode layers arranged in an alternating manner in a stacking direction, each inner electrode layer being connected alternately to one of two metalizations on an outer face of the stack in an electrically conductive manner. Each metalization is connected to an electrically conductive electrode structure via an electrically conductive contacting element (e.g., adhesive or solder). The stack-shaped actuator body has at least one predetermined breaking point, and the metalizations and/or the contacting elements have a recess in the region of the at least one predetermined breaking point. | 09-26-2013 |
20140145563 | Tubular Spring For Receiving And Pretensioning An Actuator - A tubular spring is provided for receiving and pretensioning a piezoelectric or magnetostrictive actuator of an actuator unit, e.g., for actuating a fuel injector valve in internal combustion engines, wherein the tubular spring comprises at least two types of recesses, each comprising different maximum lateral extensions in the longitudinal direction of the tubular spring. The tubular spring is designed to comprise a uniform load distribution about the circumference of the tubular spring even without welding the longitudinal sides thereof abutting one another. | 05-29-2014 |
