摘要： In a scroll type compressor, a movable scroll is engaged with an immovable scroll so that spaces are formed for taking in a fluid to be compressed. The movable scroll is revolved around a central axis of the immovable scroll, so that the spaces are displaced toward the centers of the walls while a volume thereof is reduced to compress the fluid therein. The revolution of the movable scroll is converted from a rotation of a drive shaft through an eccentric mechanism provided therebetween. The shaft is rotatably supported by first and second angular bearings, which are spaced apart from each other along a longitudinal axis of the shaft and are far from and adjacent to the eccentric mechanism, respectively. The first and second bearings are correlatively oriented, and thus an increase of a load to which the second bearing is subjected due to a force exerted upon the shaft in a cantilever manner during a compression operation is suppressed.
摘要翻译： 在涡旋式压缩机中，动涡旋盘与不动涡旋件接合，形成用于吸入要被压缩的流体的空间。 动涡旋盘围绕不动涡旋件的中心轴线旋转，使得空间朝向壁的中心移动，同时其体积减小以压缩其中的流体。 动涡旋盘的转动是通过设置在其间的偏心机构从驱动轴的转动转换出来的。 轴由第一和第二角轴承可旋转地支撑，第一和第二角轴承分别沿着轴的纵向轴线彼此间隔开并且分别远离偏心机构并且与偏心机构相邻。 第一和第二轴承相互取向，因此抑制了在压缩操作期间由于在悬臂上施加在轴上的力而使第二轴承承受的载荷的增加。

摘要： In a swash plate type compressor, refrigerant in a discharge pressure region is introduced into a crank chamber through a supply passage while the refrigerant in the crank chamber is drawn out to a suction pressure region through a bleed passage for controlling pressure in the crank chamber, whereby inclination angle of a swash plate is changed. A heat-generating sliding portion is provided in the crank chamber. The supply passage includes a communication port that communicates with the crank chamber and a first throttle portion for throttling the refrigerant. At least parts of the supply passage and the bleed passage are formed in a drive shaft. A part of the bleed passage formed in the drive shaft is located between a part of the supply passage formed in the drive shaft and an outer peripheral surface of the drive shaft.

摘要： In a variable displacement compressor that draws, compresses, and discharges refrigerant gas, the displacement is adjusted by varying the inclination of a cam plate in accordance with the difference between the pressure in a crank chamber and the pressure in cylinder bores. A pressurizing passage connects the crank chamber to a discharge passage. A bleed passage connects the crank chamber to a suction chamber. A displacement control valve is externally controlled and varies the pressure in the crank chamber by adjusting the opening size of either the pressurizing passage or the bleed passage. A suction control valve closes a duct between the suction chamber and an evaporator when the pressure in the crank chamber exceeds a predetermined level to prevent an excessively high pressure in the crank chamber.

摘要： A scroll compressor having a driving shaft 6, on which a bushing 10 and a balancing weight 9 are supported. The drive shaft 6 includes, at its end, a drive projection 6a, which is engaged with a driven groove 10a formed in the bushing 10. A spring 20 is arranged between the drive projection 6a and the bushing 10 for urging the latter radially inwardly to reduce the radius of the orbital movement of the bushing 10. A centrifugal force generated in the bushing when the drive shaft 6 is rotated causes the bushing 10 to be moved radially outwardly to increasing the radius of the orbital movement of the bushing 10.

摘要： A scroll type compressor includes a fixed scroll having a fixed spiral element and a fixed end plate, and an orbiting scroll is revolvable without rotating itself in opposition to the fixed scroll. The orbiting scroll includes an orbiting spiral element and an orbiting end plate. A plurality of compression chambers, of which volumes are decreased in response to the revolution of the orbiting scroll, are defined between the scrolls. A discharge port opens to the discharge chambers. The thicknesses of initiating sections of the fixed and orbiting spiral elements are designed larger than those of remaining sections thereof. Sealing members having a spiral shape are slidably interposed between the fixed and orbiting end plates of the fixed and orbiting scrolls, and the initiating sections of the fixed and orbiting spiral elements are in opposition to the respective end plates. The cross sectional area of an initiating section of the sealing member, which is integrally movable with at least the orbiting scroll, is larger than that of remaining section thereof. The sealing member is capable of covering a part of the discharge port.
