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: An engine piston (10) comprising a crown (12) and a tubular body portion (30) containing gudgeon pin bosses (46) and force transmitting regions (66) has the body portion forged, preferably of steel, as two or more circumferentially incomplete segments (1001, 1002) which extend about a longitudinal piston axis (14) and are joined into the tubular form by welding or the like. The segments are forged in a direction perpendicularly to the piston axis which permits the formation of regions of differing wall thickness along the tubular body length and mass saving recesses (70) between force transmitting struts (661) and (662) that are not possible with forging a unitary tubular body from one end.

Abstract: A heavy duty diesel piston includes upper and lower portions joined across a friction weld and internally contoured to provide a dual gallery structure including an outer annular gallery and a central gallery joined by passages for communicating cooling oil therebetween. The dual-gallery structure allows oil to enter from the outer gallery, which is formed by the circumferential annular recess in the crown and crown bottom, into the central gallery to cool the piston and particularly the central crown region exposed to hot combustion gases. The friction weld provides high structural integrity and minimizes the number of manufacturing steps need to attach the crown to the crown bottom.

Piston ring grooves (100, 102, 104) are also provided in either one or both of the upper and lower crowns (22, 24) which control piston combustion height. A deeper combustion bowl (72) is also available with the piston (20).

Abstract: A one-piece piston comprises a piston crown made of steel and a bottom component made of forged steel, and a cooling channel that is formed by welding the crown and the bottom component of the piston together. The cooling channel is located radially behind the annular grooves. The crown and the bottom component of the piston jointly form a central cooling chamber whose lower limiting wall is forged as one piece with the bottom component of the piston. The welding seams joining the crown and the bottom component of the piston are friction welding seams. The piston provides for superior cooling of the crown of the piston and simplifies the production of the welding seams.

Abstract: The present invention aims at reducing the amount of oil consumption in a piston using a piston ring continuously formed of resin without being provided with an abutment. A stepped portion is formed on a third land, which is located below a second ring having a construction wherein an outer ring continuously formed of polyimide without being provided with an abutment is pressed against a cylinder wall by a coil expander via an inner ring continuously formed of PTFE without being provided with an abutment. Oil spill ports are provided so as to allow communication between the stepped portion and an inner wall of the piston.
