Abstract: A crankshaft and an mounting hole have two main circular arc parts on the same circle; and two connecting parts for connecting the adjacent main circular arc parts, and have a cross-sectional shape in which the connecting parts facing each other are substantially parallel. The connecting parts of the mounting hole are formed in the shape of a large circular arc which projects inward. The torque of the crankshaft is transmitted to the mounting hole in a state where the connecting parts of the crankshaft and the connecting parts of the mounting hole which are formed in the shape of a large circular arc come into line contact with each other; therefore, the value of any local stress generated in the mounting hole can be reduced.

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.

Abstract: Present day diesel engines having aluminum piston assemblies are limited to combustion chamber pressures of approximately 12,410 kPa (1,800 psi) whereas the desire is to increase such pressures up to the 15,170 kPa (2,200 psi) range. To reach such levels the instant piston assembly includes a steel piston member having an upper cylindrical portion defining a top surface, a depending tubular wall and an annular cooling recess having one or more machined surfaces of revolution about a central axis. The cooling recess is located beneath the top surface and juxtaposed to the top ring groove for removing heat away therefrom in use. The piston member is preferably forged and subsequently machined to precisely controllable dimensions. Moreover, the piston assembly is preferably of the articulated type and includes a forged aluminum piston skirt connected to the piston member through a common wrist pin.

Abstract: Piston tops (1, 70), specially those provided with combustion chamber (2, 20) and ring zone (3, 30) have their cooling condition sensibly improved in such regions due to a better use of the cooling oil capacity by closing the cooling chamber (5, 50) and the region 2I under the combustion chamber by annular ring members (96, 13) in a resilient material, e.g., a polymeric material or, preferably a spring steel, which clamp under the cooling chamber (5, 50) and the region 2I with dimensional interference respectively with grooves (10, 100), notches (11, 110) and groove 15. Methods for the manufacture of such top portion having a reduced compression height are also described.

Abstract: Present day diesel engines having aluminum piston assemblies are limited to combustion chamber pressures of approximately 12,410 kPa (1,800 psi) whereas the desire is to increase such pressures up to the 15,170 kPa (2,200 psi) range. To reach such levels the instant piston assembly includes a steel piston member having an upper cylindrical portion of a diameter "D" and a compression height "CH". The ratio of the compression height "CH" to the diameter "D" being within the range of from 60% to 45%. The piston member is preferably forged and subsequently machined to precisely controllable dimensions. Moreover, the piston assembly is preferably of the articulated type and includes a forged aluminum piston skirt connected to the piston member through a common wrist pin. Engine manufacturers are also demanding a smaller engine package size while retaining power output, improve fuel consumption and decreased emissions. The subject piston member provides a simple and inexpensive solution to the increased power output package size relationship. To insure a small engine package, the piston member has a compression height to maximum diameter ratio within the range of from 60% to 45%. The piston member is preferably made from a steel forging to insure a reduced porosity over that of existing standard castings.
