    摘要: A switchable support element (1) requiring only a small design space. For this purpose, a slide (12) that serves to couple an inner element (6) to an outer housing (3) in the support element (1) is positioned laterally in a housing (2) arranged in the cylinder head (5). At the same time, a bore (8) in the inner element (6) for the slide (12) is made as a pocket bore, the housing (2) being seated through an annular extension (11) directly in a bore (9) of the outer housing (3). The slide (12) can be displaced electromagnetically or hydraulically in at least

    摘要: A pick-style tool that includes an elongate tool body with an axially forward end and an axially rearward end, and a hard insert affixed to the tool body at the axially forward end is disclosed. The hard insert comprises a WC-cermet comprising tungsten carbide and about 5 wt. % to 27 wt. % Co—Ni—Fe-binder. The Co—Ni—Fe-binder is unique in that even when subjected to plastic deformation, the binder substantially maintains its face centered cubic (fcc) crystal structure and avoids stress and/or strain induced transformations.

    摘要: A cutting insert including a flank face, a rake face, and a cutting edge at the intersection of the flank and rake faces that is useful in the chip forming machining of workpiece materials is disclosed. The cutting insert comprises a cermet comprising at least one hard component and about 2 wt % to 19 wt % Co--Ni--FE-binder. The Co--Ni--FE-binder is unique in that even when subjected to plastic deformation, the binder substantially maintains its face centered cubic (fcc) crystal structure and avoids stress and/or strain induced transformations.

    摘要: A tensioner for the chain or the belt of an internal combustion engine, for example of the camshaft drive, includes a cylindrical tensioner housing (2) with a piston (1) loaded by a compression spring (13) arranged therein, the tensioner housing and the piston being axially displaceable relative to each other. The displaceable element which is displaceable relative to the fixed element in chain tensioning direction, is surrounded by a first stop ring which limits its backward movement. According to the invention, the first stop ring is configured as a retaining clip (15) whose arms engage into a locking groove (16) of the tensioner housing (2) under radial pre-stress and, upon a displacement thereof, can come to bear axially against a stop surface of the receiving housing (3).

    摘要: The invention concerns a hydraulic play-compensation element including a groove (11) in the housing (1) to be located in such a way that, whatever the position of the plunger (2), a length (19) of the plunger is always supported by the cylinder wall above the groove and the securing ring (12) is centered radially around the plunger by means of a recess (14) in the plunger, the recess having a ramp at least at its lower end. The invention thus avoids weakening of the material in the upper part of the plunger.
