摘要： 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.

摘要： An example fuel injector orifice plate assembly includes a plastic plate within which is an orifice for metering and directing fuel flow in a desired spray pattern, and a metal support plate for supporting and maintaining the stability of the desired spray pattern generated by the orifices within the plastic plate. The orifice plate includes orifices sized to provide a desired spray pattern of fuel. The metal support plate is more rigid than the orifice plate and provides the desired strength and rigidity for withstanding the cyclical pressure fluctuations caused by operation of the fuel injector.

摘要： The present invention provides an apparatus that can form a plurality of orifices where the orifices are consistent dimensionally, such as, for example, the diameter, the surface roughness or the entry and exit configurations. Preferably, the invention provides a laser machining apparatus. The apparatus includes a laser light source that provides a generally coherent light beam along the beam's axis. The apparatus also includes a light directing device to direct a first portion of light from the light beam to a work piece at a first angle of incidence relative to the axis of the light beam during a first time interval to form at least one of an orifice and a chamfer. The apparatus further includes an adjustable beam splitter assembly to direct another portion of the light beam to form the other of the at least one of an orifice and a chamfer in the work piece during a second time interval that overlaps a portion of the first time interval. The method includes providing at least a first beam and a second beam that are emitted from the laser light source towards the workpiece; and rotating at least a first beam and a second beam with respect to the longitudinal axis. The method further includes forming at least one orifice in the workpiece with at least one of the first and second beams during a first time interval; and forming the at least one chamfer in the workpiece with the other of the first and second beams during a second time interval that overlaps a portion of the first time interval.
