摘要： A workpiece is coated with carbonizable polymer for laser machining an aperture through the workpiece. The workpiece is protected by the polymer during laser machining so that the surface of the workpiece and areas surrounding the aperture are substantially free of debris produced by the laser machining process. The carbonized polymer is removed after laser machining. A method of forming an aperture by a laser on a thin metallic plate is also described.

摘要： A method and fuel injector for precision setting of valve lift, using a valve body shell (42) telescoped over the valve body (60), the shell (42) having a nonmagnetic extension welded to the valve body shell (42) and to the end of an inlet tube (16) providing a solenoid pole piece, with the valve body (60) and shell (42) adjusted to set the valve lift and thereafter welded together. Interference fit portions stabilize the adjusted position of the members preparatory to welding, and displaced material in a locking groove (102) creates a mechanical interlock between the valve body (60) and shell (42) to stabilize the members in their adjusted positions after welding so that the set lift is minimally affected by weld shrinkage. An external radial groove 18 allows radial bending as the weld cools to minimize axial shift of the parts and thus the effect on the set valve lift.

摘要： 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.

摘要： In a method for the production of a gradient encapsulation layer 20 on a piezoelectric actuator 1, based on this gradient encapsulation layer 20, the piezoelectric actuator 1 does not 5 require an additional housing-like enveloping structure in order to be protected externally. The gradient encapsulation layer 20 is produced by cold gas spraying of particles having different material properties.

摘要： A piezoelectric stack (1) has alternately successive piezoelectric layers (2) and inner electrode layers (3, 4) which are alternately electrically connected to two outer electrodes (7, 8) which are arranged on the outer side (5, 6) of the piezoelectric stack (1).

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： To optimize the results of rounding and therefore to optimize the high pressure resistance of the component, it is firstly proposed that prior to the machining step of hydro-erosive rounding, the edge (5) and the surfaces (4, 6) of the high pressure-resistant component (1) which adjoin the edge (5) are each placed under compressive stresses in the region of their surface by means of a grinding and/or honing process. Also with regard to the method, and with regard to an apparatus for the hydro-erosive rounding, it is proposed that a closure element (9) is inserted into the continuing first bore (2), downstream of the second bore (3), which branches off from the first bore, as seen in the main direction of flow (S) of the liquid (8) mixed with abrasives (7), in order to divert the liquid (8) mixed with abrasives (7) from the first bore (2) into the second bore (3).
