摘要： The invention relates to a coil spring from an alloy steel and to a method for producing said coil springs. The aim of the invention is to produce coil springs that have a good core hardness, showing very little wear even under high constant loads, and to provide a simple method for producing such spring coils. To this end, the coil springs are produced from a steel that contains nitride-forming alloy components, wherein a nitride-containing diffusion layer forms at least part of the surface of the coil spring. According to the method for producing the inventive coil springs the surface of coil springs that are produced from a steel that contains nitride-forming alloy components is at least partially converted to a diffusion layer by nitrating it with a nitrogenous treatment gas. The nitrogen content in the treatment gas is selected such that no connecting layer is formed on the surface of the coil spring.

摘要： The invention relates to a wiper blade for cleaning glass panes of motor vehicles. The wiper blade is provided with a long, rubber-elastic wiper strip that can be placed on the glass pane. Said wiper strip is arranged on the bottom strip surface (13) that faces the glass pane of a long striplike carrier element (12) made of an elastic steel. A device (15) for attaching the wiper blade to the free end that is loaded to the glass pane of a driven wiper arm (16) that is placed on the motor vehicle is soldered on the other top strip surface (11) opposite the glass pane in the central area of the carrier element. Particularly advantageous results are obtained in terms of the requirements for said carrier element if the latter is made of alloyed tempering steel, the alloy fractions being as follows: carbon (C) 0.18 % to 0.36 %; silicon (Si) 0.40 % to 0.50 %; manganese (Mn) 1.10 % to 1.80 %; phosphorus (P) 0.015 % to 0.035 % and sulfur (S) 0.035 % to 0.04 %.

摘要： The invention relates to a helical compression spring (40) for use in a structural member of a fuel injection system, for example a structural element in the form of a fuel injection valve (1). Said helical compression spring (40) has a spring wire cross-section corresponding to a rectangle with rounded edges and an inner surface (46) constituting the interior of the helical compression spring (40) that is strongly cambered. Said cross-section contour of the spring wire reduces the shearing strain when the helical compression spring (40) is subjected to stress, thereby allowing to reduce the length of the helical compression spring while maintaining the same spring rate (K). The lateral surfaces (42) of the spring wire facing each other in the helical compression spring are at least approximately parallel so that they flatly rest against each other at the ends of the helical compression spring (40) due the helix height (H) that is reduced in said area, thereby avoiding a decrease of the spring force when the helical compression spring (40) is prestressed.
