    Abstract: The invention relates to a guide arrangement, especially for a piston-cylinder arrangement, comprising a cylinder (3) in which a bearing section of a piston (2) can be displaced axially along its inner bore (5) configured as a piston bearing surface (6) and a piston (2) to which a connecting rod can be coupled by means of a pin. At least two cylindrical and peripheral bearing sections (9a, 10a) radially delimiting the piston (2) and serving as support on the bearing surface (6) of the cylinder (3) are releasably arranged on said piston (2) by means of two parts (7, 8) of the piston (2), at least one of which penetrates a central opening of the bearing sections (9a, 10a). The forces and torques are evenly distributed on the at least two bearing sections in the axial extension of the piston (2) in such a way that the bearing sections are arranged outside the axle of the pin and at least one section (9a) of the at least two bearing sections (9a, 10a) is completely arranged on one side of the axle of the pin (20) and at least the other section (10a) of the at least two bearing sections (9a, 10a) is completely arranged on the other side of the axle of the pin (20). In addition, the bearing sections (9a, 10a) are fixed at a fixed reciprocal axial distance (11) in relation to each other. Force is transmitted from the pin to the bearing sections (9a, 10a) exclusively through the central parts (7, 8) of the piston (2). A favorable tribologic pairing is achieved in that one of the materials of the pairing bearing section (9a, 10a) guide surface (6) is chosen from the group comprising polycrystalline diamond, amorphous hydrocarbon, tetragonally coordinated hydrocarbon and metal-containing hydrocarbon and in that the other material of the pairing is selected from the group comprising mesophase graphite and ultrafine grain graphite.

    Abstract: In a piston-cylinder assembly of an internal combustion engine, especially a two-stroke engine, at least the piston-sliding surface of the cylinder is made of an aluminium alloy. Moreover, the basic material of the piston (1) is an alluminium alloy and at least 80 % of its sliding surface is given a sliding coating (3, 4). The sliding coating (3, 4) on the piston (1) is usually metallic and galvanically applied. The aim is to provide an economically producible piston coating with properties at least as good as those of the former galvanically applied coatings. To this end the cylinder sliding surface has a roughness Ra of less than 1 mu m, while the piston sliding surface consist of resin-bound graphite. The piston rings (6) are made of cast iron or steel and have a convex sliding surface.

    Abstract: A method for manufacturing a sliding part for a hermetic compressor is disclosed. Since the abrasion resistance and corrosion resistance of the sliding part is increased, the energy consumption efficiency is improved and the performance of the compressor can be enhanced. In addition, since the manufacturing process is shortened, the production cost can be reduced and the manufacturing time can be reduced. Moreover, since the thickness change of the sliding part is minimized, the defective rate of the part size can be reduced and its quality can be improved.
