Abstract: A piston for a fluid-actuated working cylinder, with a piston base unit which is coaxial to a piston longitudinal axis, consisting of a rigid core body which has radial outer peripheral surface and of an annular filling body which is seated in an annular receiving groove. The receiving groove is coaxial to the piston longitudinal axis and in the region of the radial outer peripheral surface is designed with a radially outwardly facing groove opening in the core body. The piston further includes a ring element which consists of plastic. The ring element radially outwardly coaxially encompasses the piston base unit at least in the region of the filling body, being radially supported with a radial inner peripheral surface on the piston base unit, projecting radially beyond the radial outer peripheral surface of the core body and comprising an axially orientated axial support surface radially outside the piston base unit on its two axial face sides. The piston further includes an annular enveloping body which has rubber elastic characteristics.

Abstract: A brake cylinder piston assembly having a composite piston head having a bore formed therethrough, a cup positioned in the bore and coupled to the piston head, and a hollow rod securely welded to the cup. The cup is coupled to the piston head by a series of fingers with locking tabs that extend around the bore of the piston head and engage a rim of the cup. The bore of the piston head has two steps that correspond to the two steps formed into outside of the cup so the two step outer diameter of the cup is securely seated in the two step inner diameter of the bore. A plastic load disc having a hemispherical cavity may be positioned within the end of the hollow rod that is secured to the cup to absorb high energy hand brake releases.

Abstract: A method for the production of a forged piston for an internal combustion engine, having a combustion depression provided on the piston head. The piston is formed from a first cylindrical unmachined part having at least one flat face made of oxidation-resistant steel and a second cylindrical unmachined part having at least one flat face made of hot-forgeable steel, with the same diameters. The two unmachined parts are formed to produce a piston blank, by means of forging, causing the combustion depression to be formed from oxidation-resistant steel. The piston blank is subsequently finished via machining to produce a piston ready for installation in the internal combustion engine. Simple and cost-effective production of a piston having a reduced tendency to oxidize at the edge of the depression, and improved protection against wear caused by erosion, is achieved in that the unmachined parts are brought together at their flat faces and aligned with respect to their diameters (d), so that the faces form a minimal projection and a minimal parting. Subsequently, the unmachined parts are fixed in place at the parting by a minimal number of weld points.
