Abstract: What is proposed is a method for the production of a piston (1) made of steel, for an internal combustion engine, in which the upper piston part (3) is produced using the forging method, and the lower piston part (4) 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 cooling channel piston has a radially circumferential cooling channel located behind a ring field. The cooling channel piston is forged from a steel material and the cooling channel is worked in by machining between an upper part below the ring field and a lower part above the piston bosses and the piston skirts. The cooling channel extends behind the ring field in the direction of an upper face of the upper part, it being provided that the cooling channel piston has above its piston bosses and piston skirts an outwardly oriented support region. A closing element, which closes the cooling channel after the production thereof, is fastened between the lower edge of the ring field and the support region.

Abstract: A compressor used in a refrigerating cycle is provided as a miniaturized and lightweight unit at low production cost by selecting an optimal material to constitute components or by forming the housing in a specific shape so as to allow the components to have smaller wall thicknesses while assuring sufficient strength. A tough material achieving a tensile strength greater than 800 N/mm2 is used when forming at least one of the components constituting the housing and the internal mechanisms. In addition, over the area of the housing where the bottom surface and the inner circumferential surface connect with each other, the bottom surface forms an R-shaped portion and the inner circumferential surface forms a sloping portion or an R-shaped portion.

Abstract: A single-part cooling channel piston for a combustion engine with a piston head of forged steel comprises a combustion bowl in the piston crown, a ring wall with ring belt and an all-round closed cooling channel level with the ring belt. The piston skirt is connected to the pin bosses attached to the piston head. Inexpensive manufacture together with improved cooling and good form stability of the piston is achieved by providing the cooling channel with holes spread over its circumference towards the piston crown and spaced such that the piston material present between such holes forms supporting ribs for the piston crown.
