摘要： A scroll type compressor includes a front housing, a fixed scroll, a movable scroll and a rear housing, and its lateral cross section has a substantially oval shape. The spiral element of the movable scroll is located in the space defined by the front housing and the fixed scroll in such a way as to engage with the spiral element of the fixed scroll. The space defined by the fixed scroll and the rear housing serves as a discharge chamber where compressed refrigerant gas is discharged. Since this compressor has the same compression displacement as that of a compressor having a circular cross section, this compressor can be placed in narrow space whose width is less than the width of the circular compressor, without any reduction in the cooling performance.

摘要： A scroll type compressor comprises an immovable scroll defining a spiral space, and a refrigerant is introduced into an outerhost zone of the spiral space. The compressor further comprises a movable scroll engaged with the immovable scroll such that the outermost zone of the spiral space is divided into an inner section and an outer section by an outermost portion of the movable scroll. The movable scroll is revolved around a center axis of the immovable scroll such that the inner and outer sections are alternatively displaced as a compression chamber toward a center of the immovable scroll, and a refrigerant inlet port of the inner section is defined by a termination of the outermost portion of the movable scroll. The termination is disengaged from and engaged with the immovable scroll during the revolution of the movable scroll to close and open the inlet port of the inner section. The immovable scroll has a communication passage formed in a base portion thereof, and the inner and outer section is in communication with each other through the communication passage only when the termination is disengaged from the immovable scroll so that the inlet port of the inner section is opened, whereby the refrigerant can be fed to the inner section not only through the inlet port thereof, but also through the communication passage until the termination is engaged with the immovable scroll so that the inlet port of the inner section is closed.

摘要： A scroll type compressor comprising mutually mating stationary and movable scroll members, a drive shaft, a counterweight, a slide key extending from the drive shaft, and a drive bush slidably fit on the slide key. The counterweight is immovably fit on the drive shaft. The slide key has a first axis offset from the longitudinal axis of the drive shaft for causing the movable scroll member to revolve around the longitudinal axis of the drive shaft, and a second axis perpendicular to the first axis. In the second form of the compressor, the counterweight has a guide portion having a first axis offset from the longitudinal axis of the drive shaft for causing the movable scroll member to revolve around the longitudinal axis of the drive shaft, and a second axis. The drive bush is slidably fit on the guide portion. The drive bush is movable along the second axis of the slide key or the guide portion to a smaller extent in one direction by which the eccentricity between the longitudinal axis of the drive shaft and the longitudinal axis of the drive bush is increased, and to a greater extent in the other direction by which the eccentricity is decreased.

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： A variable displacement compressor for forming a refrigerant circuit with an external refrigerant circuit includes a housing, a drive shaft, a swash plate, a shaft seal member, a supply passage, a control valve and a gas passage. The housing has a suction chamber, a crank chamber, a discharge chamber and a shaft seal chamber formed therein. The discharge chamber is in communication with the crank chamber through the supply passage. The supply passage has the shaft seal chamber. The discharge chamber is in communication with the external refrigerant circuit through the gas passage. The supply passage is formed differently from the gas passage. A part of the supply passage is located adjacent to the suction chamber and nearer to the suction chamber than the discharge chamber.
