Abstract: A method for the production of a piston made of steel, for an internal combustion engine, in which the upper piston part is produced using the forging method, and the lower piston part is produced using the forging or casting method, and they are subsequently welded to one another. To simplify the production method and make it cheaper, the upper piston part is forged using the method of hot forming and of cold calibration, to finish it to such an extent that further processing of the combustion bowl and of the upper cooling channel regions can be eliminated.

Abstract: A piston capable of reducing the frictional resistance between skirt portion and a cylinder inner surface and improving fuel efficiency is provided. The invention is a piston for an internal combustion engine wherein when the piston slides along a cylinder inner surface, a high surface pressure portion occurs at a center of each skirt portion and low surface pressure portions occur at both sides of the high surface pressure portion. The high surface pressure portion of plural portions is provided with a horizontal groove. The low surface pressure portions of the plural portions are provided with an inclined groove that is inclined downward toward the high surface pressure portion and that is connected to an end portion of the horizontal groove.

Abstract: A compressor having a compression element with a cylinder in which a compression space is constituted, a suction port and a discharge port which communicate with the compression space in the cylinder, a support member which closes an opening on the cylinder and a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member. A compression member, whose one surface crosses an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and is disposed in the cylinder to be rotated by the rotary shaft, compresses a fluid sucked from the suction port to discharge the fluid via the discharge port. A vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member partitions the compression space in the cylinder into a low pressure chamber and high pressure chamber. A shaft seal which is disposed on an end portion of the main bearing, on a side opposite to the compression member, abuts on the rotary shaft.
