摘要： When sliding elements, slide bushings, vanes and Oldham rings employed in various types of refrigeration compressors and other applications meet the following conditions, they resist sticking to aluminum-base components, resist depletion of the oil film on slide faces, and exhibit excellent wear resistance. Firstly, the elements must comprise an iron-base sinter having closed cells on at least the slide face. Secondly, in order for the oil film to be maintained on the slide face by the closed cells and to enhance lubricating properties, the proportion of closed cells having circular-equivalent diameter of 10 &mgr;m or less, i.e. the number of ≦10 &mgr;m cells/total number of cells, must equal 85% or more, and the opening area of the closed cells on the slide face must equal 5% or less. Finally, the sliding element density must be 7.3 g/cm3 or higher.

摘要： An orbiting scroll is engaged to and moved orbitally in relation to a fixed scroll at variable speeds. An offset surface is provided in at least one of the wraps of the fixed scroll and/or the orbiting scroll, by which a space S is created in one of the compression chambers formed between the fixed scroll and the orbiting scroll, which is thereby unsealed and opened to the inlet port side. The offset surface has a length from a position in the spiral length which satisfies the required compression ratio of one of the compression chambers in a low speed operation to the end of the spiral. An injection port is positioned such as to open to an unsealed area of this compression chamber, and gas injection shutoff and resumption is controlled through this injection port as appropriate to the situation.

摘要： In a sealed electric scroll compressor, lubricating oil is collected in an oil collection pan mounted under a compression mechanism after the compression mechanism is lubricated thereby, the lubricating oil collected in the oil collection pan is discharged from a small hole at the side of the oil collection pan which is located remote from a delivery pipe for delivering a high-pressure refrigerant gas outward from a sealed container of the sealed electric compressor. The high-pressure refrigerant gas flows between the inner wall of the sealed container and a vertical cut part formed on the circumference of a stator of an electric motor.

摘要： A compressor for a refrigeration machine is provided without any problems of reduction in the life of a thrust bearing structure even when a substitutive coolant not containing any chlorine is used. In the compressor for a refrigeration machine having a thrust bearing made of steel for supporting a thrust load applied to a drive shaft, a thrust bearing surface made of a material different from that of the drive shaft is formed in the thrust bearing by means of a surface treatment. Alternatively a washer defining the thrust bearing surface may be surface treated to provide a material different from that of the drive shaft. The washer may also be made of a material different from that of the drive shaft. According to the the present invention, even when a boundary lubricating state is produced between the drive shaft and the thrust bearing surface sticking is prevented. As a result, the life of the thrust bearing structure of the drive shaft can be made longer and a problem of reduction in the life of the thrust bearing structure can be avoided even when a substitutive coolant not containing any chlorine is utilized.

摘要： A scroll compressor is designed to exert a stable pressure on the rear surface of the rotary scroll without causing excessive pressure rise or pressure gradient by the lubricating oil which flows out from a back pressure partitioning member in a very little gap of an axial supporting portion. A bearing member 18 has an inner portion extending radially inwardly from annular groove 22 and an outer portion extending radially outwardly from the annular groove 22 to an inner edge of an axial supporting portion 24. The inner and outer portions of the bearing member 18 are formed in a bottom portion of the bearing member 18 and have a difference in level d relative to a bottom surface of the axial supporting portion 24.
