Abstract: In a piston head of a multiple component piston for internal combustion engines, the piston floor continues radially outwards into the ring section which is provided with the piston ring grooves, the supports which carry the hubs are arranged at a distance from the inner face of the ring section and the piston pin which bears the piston shaft can be mounted in the bores of the piston pin boss. An improved manufacture of the piston head is ensured by connecting the ring section with the piston floor via a weld, solder, friction or positive locking joint.

Abstract: Austenitic cast iron with mainly vermicular and/or nodular graphite is useful as a reinforcing material intermetallically bound to the aluminium base material of the pistons of an internal combustion engine. This material provides improved binding solidity with the adjacent aluminium base material of which the piston is made. The reinforcing material can be composed of different layers.

Abstract: A rotary compressor in which 1,1,1,2-tetrafluoroethane is used as a refrigerant and polyol ester which is compatible with the above refrigerant is used as an oil, in which a roller is formed of an iron material, and a vane of a carbon-containing composite aluminium material, and in which the corrosion of the roller and/or vane due to hydrolysis of polyol ester oil is prevented by restraining the generation of sliding friction heat between the roller and vane, thereby reducing the risk of the roller and/or vane being worn.

Abstract: A method of manufacturing an oil pump rotor of aluminum alloy excellent in resistance to wear, strength at high temperature, and dimensional precision, in which rapidly solidified aluminum alloy powder of high performance containing a dispersion intensifying particle-forming element such as a transition element, solution-treating and age-hardening element, and hard particles is solidly bound through one hot forging so as to be subjected to sizing treatment. Rapidly solidified aluminum alloy powder is subjected to cold or warm pre-forming process to be 75 ∩ 93 % in relative density, undergoes heating and degassing treatment for 0.25 to 3 hours in the atmosphere of inert gas at a temperature ranging from 300 to 560 °C, and, immediately afterward, is subjected to hot coining at a temperature ranging from 300 to 560 °C so as to be formed into a solid body having a porosity ranging from 2 to 5 %, whereby a product thus solidified is subjected to sizing treatment. Since re-reaction between steam and aluminum is controlled by inert gas when heating the pre-formed product, hot coining is performed in the state that the solid phase dispersion is liable to occur, and powder is solidly bound through one forging. Because of porosity of 2 to 5 % remaining in the solidified product on completion of hot coining, dimensional precision can be increased by subsequent sizing, thereby enabling the manufacture of a rotor sufficiently withstanding a high temperature application.

Abstract: A piston assembly comprising a piston head, and a connecting rod one end of which is secured to the piston head so as to be pivoted relative to the piston head about a predetermined axis. The end of the connecting rod supports a cross-member opposite ends of which are received in respective recesses defined in the piston head. The recesses define arcuate bearing surfaces which are contacted by corresponding arcuate bearing surfaces defined by the cross-member. The piston head is formed from at least two components and each recess is defined by a respective one of the components. The components are permanently secured together after insertion of the cross-member into the recesses such that subsequent separation of the piston head and connecting rod is prevented. The piston assembly may support helical sealing rings.
