摘要： A scroll type compressor has a movable scroll which is supported by a drive shaft by way of an eccentric pin in a housing. The movable scroll engages in an orbital movement for defining a compression chamber with a fixed scroll which is disposed opposite to the movable scroll. The compression chamber decreases in size in accordance with the orbital movement of said movable scroll for compressing gas in the compression chamber. A first ring orbits together with the movable scroll between the movable scroll and the housing, for receiving compressive reaction force acting on the movable scroll. A second ring which is secured to the housing receives the compressive reaction force received by and acting on the ring.

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： A base plate 41 of a movable scroll member 4 has, at its outer periphery, a section 44 with no scroll wall, while a scroll wall 22 of a stationary scroll member 2 has a section 24 for connecting to an outer cylindrical shell 22. These sections 44 and 24 make a relative lateral slide movement during an orbital movement of the movable scroll member 4 with respect to the stationary scroll member 2. These sections 44 and 24 have axially faced inner and outer edges 44-1 and 24-1, over which the relative lateral movement occurs. These inner and outer edges 44-1 and 24-1 are bevelled, the bevelling being such that any skewed movement of the movable scroll member with respect to the stationary scroll member does not cause locally increased contact pressure, thereby preventing galling as well as seizing.
