    Abstract:  圧縮機120は、炭素の二重結合を有するハイドロフルオロオレフィンの単一冷媒またはハイドロフルオロオレフィンと炭素の二重結合を有しないハイドロフルオロカーボンとを含む混合冷媒が使用されるとともに、冷凍機油103の劣化を抑制する添加剤と磨耗防止剤とを含む前記冷凍機油103が使用され、これら混合冷媒および冷凍機油103に曝される、HRC47~55の硬度を備える摺動部を有する。これにより、冷媒と冷凍機油103の分解・重合を抑制することができ(すなわちスラッジの発生を抑制でき)、圧縮機120の摺動部、例えばベーン110とピストン109の耐摩耗性を維持することができる。その結果、圧縮機120およびそれを用いた冷凍サイクル装置の信頼性を確保することができる。

    Abstract: An improved structure for carbon-carbon composite piston architectures is disclosed. Initially, the carbon fabric or tape layers are prepregged with carbonaceous organic resins and/or pitches and these plies (21) laid up or molded about a mandrel, to form a carbon-fiber reinforced organic-matrix composite billets (20) shaped like a "U" channel having legs (26, 27), a "T"-bar, or a combination of the two. The molded carbon-fiber reinforced organic-matrix composite part is then pyrolized in an inert atmosphere, to convert the organic matrix materials to carbon. At this point, cylindrical piston blanks (22) are cored from the "U"-channel, "T"-bar, or combination part. These blanks are then densified by reimpregnation with resins or pitches which are subsequently carbonized. Densification is also accomplished by direct infiltration with carbon by vapor deposition processes. Once the desired density has been achieved, the piston billets are machined to final piston dimensions; coated with oxidation sealants; and/or coated with a catalyst.

    Abstract: A three-dimensional piston molding is fabricated from a mixture of chopped, carbon tow filaments of variable length, which are prepregged with carbonaceous organic resins and/or pitches and molded by conventional molding processes into near net shape, to form a carbon-fiber reinforced organic-matrix composite part. Continuous reinforcement in the form of carbon-carbon composite tapes or pieces of fabric can be also laid in the mold before or during the charging of the mold with the chopped-fiber mixture, to enhance the strength in the crown (21) and wrist-pin areas (23). The modled chopped-fiber reinforced organic-matrix composite parts are then pyrolyzed in an inert atmosphere, to convert the organic matrix materials to carbon. These pyrolyzed parts are then densified by reimpregnation with resins or pitches, which are subsequently carbonized. Densification is also accomplished by direct infiltration with carbon by vapor deposition processes. Once the desired density has been achieved, the piston molds are machined to final piston dimensions, and piston ring grooves are added. To prevent oxidation and/or to seal the piston surface or near surface, the chopped-fiber piston (20) is coated with ceramic and/or metallic sealants; and/or coated with a catalyst.

The piston member (78) is preferably forged and subsequently machined to precisely controllable dimensions, and has a ratio of TRH to D of less than 0.06. Moreover, the piston assembly (76) is preferably of the articulated type and includes a forged aluminum piston skirt (80) connected to the piston member through a commmon wrist pin (82).

To reach such levels the instant piston assembly (76) includes a steel piston member (78) having an upper cylindrical portion (96) 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 (78) is preferably forged and subsequently machined to precisely controllable dimensions. Moreover, the piston assembly (78) is preferably of the articulated type and includes a forged aluminum piston skirt (80) connected to the piston member (78) through a common wrist pin (82). Engine manufacturers are also demanding a smaller engine package size while retaining power output, improve fuel consumption and decreased emissions. The subject piston member (76) provides a simple and inexpensive solution to the increased power output package size relationship. To insure a small engine package, the piston member (78) has a compression height to maximum diameter ratio within the range of from 60 % to 45 %. The piston member (78) is preferably made from a steel forging to insure a reduced porosity over that of existing standard castings.
