    Abstract: A powder-metallurgically produced piston body for a piston-cylinder arrangement, in particular a shock absorber piston, has a one-part piston body, a revolving or circumferential web that protrudes radially outwardly from outer surface of the piston body, longitudinal webs, and at least one traverse groove. A collar-shaped seal, made of thermally deformable material, is formed onto the piston body such that the revolving or circumferential web and the support webs are formed into the seal over at least a part of their heights.

    Abstract: A method for producing a one-part piston body for a piston-cylinder arrangement, in particular a shock absorber piston, is disclosed. The method may include in a first step, pressing a green compact comprising a revolving web and longitudinal support webs from a sinterable metallurgical powder. In a second step, the green compact may be sintered to form a blank. In a third step, radially disposed stamping tools may be used to form, under material displacement, transverse grooves into at least a part of the support webs through cold deformation. In a fourth step, the blank provided with transverse grooves may be calibrated to its final form through pressing with calibrating tools.

    Abstract: A valve assembly progressively opens to provide a smooth transition from a closed position to an open position. The fluid pressure reacts against a valve plate in a non-symmetrical manner to progressively open the valve. The valve can include a plurality of varying sized fluid passages or valve lands can be positioned eccentrically to each other to provide a non-symmetrical pressure area.

    Abstract: A high-performance piston core including a first piston cylinder and a second piston cylinder, with a piston center longitudinally disposed between and magnetically coupling the first piston cylinder and the second piston cylinder. The piston center is made of high-performance magnetic material, such as Cobalt steel (CoFe), Silicon steel (SiFe), Vanadium/Cobalt steel (Permendur), alloys thereof, or the like. The high-performance magnetic materials exhibit high magnetic permeability and reduce the magnetic reluctance of flux bottlenecks. In addition, high-performance magnetic materials typically saturate at a higher flux density than the conventional magnetic materials. The first piston cylinder and the second piston cylinder can be made of conventional magnetic material, such as low-carbon steel. The first piston cylinder can include a ring disposed about an end, where the end is longitudinally attached and magnetically coupled to the piston center.

    Abstract: A shock absorber includes a valve assembly with a low speed oil flow circuit and a mid/high speed oil flow circuit. Both circuits control fluid flow through the valve assembly in the same direction. The low speed oil flow circuit is tunable in order to provide low speed damping to improve both the vehicle control and handling. The tuning of the low speed oil flow circuit is accomplished by supporting a low speed valve disc at a position radially inward of its outer edge to control the rate at which the low speed oil flow circuit opens. The valve assembly of the present invention can be located within either a base valve assembly or a piston valve assembly.

    Abstract: A magnetorheological piston includes a magnetorheological-piston coil and a magnetorheological-piston core. The magnetorheological-piston coil has a longitudinal axis. In one expression, the magnetorheological-piston core includes at least two separate core pieces, wherein each of the core pieces is a powder-metal core piece, and wherein the coil is positioned to circumferentially surround at least a portion of at least one of the core pieces. In another expression, the magnetorheological-piston core includes separate upper core, center core, and lower core pieces. The center core piece is located longitudinally between the upper core and lower core pieces and has a circumferential surface positioned radially inward from the inner-diameter portion of the coil. The coil is longitudinally positioned between the upper core and lower core pieces. In one example, each of the upper core, center core, and lower core pieces is a powder-metal core piece.

    Abstract: A pressure cylinder for a hydraulic actuation device in motor vehicles includes a housing (1) with an internal cylinder (2,3). A piston (6) is displaceable in the internal cylinder for forming a pressure space (12) for a hydraulic fluid. The piston includes a hemispherical socket (10) in an indentation (9). A spring (18) is arranged in the pressure space (12), and a tappet (7) is connected by a transmission part with a hemispherical cap (8). The tappet (7) is in a frictional and swivelable engagement in the socket (10) in an indentation (9) by the force of the spring (18). The piston is a deep-drawn, cup-shaped part and includes a filling piece (13) in the interior of the piston (6). An annular space (15) is disposed at a piston surface (14) facing toward the pressure space (12). The annular space (15) is for receiving the spring (18) in a compressed state when the piston (6) is in a top dead center position.
