摘要： Scroll compressors may preferably include a stationary scroll, a drive shaft, a crank shaft coupled to the drive shaft and a bush coupled to the outer surface of the crank shaft. A seal is preferably disposed between the bush and the crank shaft and the seal is elastically deformable in the radial direction of the crank shaft. A movable scroll may be coupled to the crank shaft and disposed adjacent to the stationary scroll. A compression chamber is defined by a space between the stationary scroll and the movable scroll, such that fluid is compressed within the compression chamber when the movable scroll revolves or orbits with respect to the stationary scroll. Further, a discharge port is preferably defined within the movable scroll and adapted to release the compressed fluid to a side that is opposite of the stationary scroll.

摘要： A first lubricating oil passage and a second lubricating oil passage, extended from a contacting surface between a partition wall and a fixed scroll are formed in the partition wall (middle housing). A recess for communicating the first lubricating oil passage with the second lubricating oil passage is formed on the fixed scroll. Accordingly, the lubricating oil amount between the first lubricating oil passage and the second lubricating oil passage is easily controlled by adjusting the size of the recess.

摘要： A scroll type compressor which includes a fixed scroll and an orbiting scroll. Each scroll includes an end plate, a spiral element, at least one airtight compression chamber formed between the fixed and orbiting scrolls, a discharge port, and a drive mechanism for revolving the orbiting scroll relative to the fixed scroll, for compressing fluid in the compression chamber. The fixed spiral element and the orbiting spiral element include relatively thick tip portions having oppositely disposed flat faces. These faces are arranged in such a way as to periodically approach each other during the revolution of the orbiting scroll. A buffer portion is provided on at least one of the flat faces of the fixed and orbiting tip portions, for preventing over-compression of the fluid trapped between the flat faces.

摘要： An electric compressor has a compressor housing, a compression mechanism, an electric motor, an accommodating portion and a motor drive circuit. The compressor housing has a circumferential wall and a central axis. The compression mechanism is arranged in the compressor housing for compressing fluid. The electric motor is operatively connected to the compression mechanism for driving the compression mechanism. The accommodating portion is provided on an outer surface of the compressor housing and defines an accommodating space. The inner surface of the accommodating space includes a bottom surface and a side surface. The bottom surface is defined as a radially inward surface of the inner surface relative to the central axis. The side surface surrounds a periphery of the bottom surface. The bottom and side surfaces are defined by the compressor housing. The motor drive circuit is arranged in the accommodating space for driving the electric motor.

摘要： An oil storage area (45a) is defined on the bottom of a motor chamber (45) of a scroll compressor (1). An oil transfer route (4a) is defined in the portion of a center housing (4) that corresponds to the storage area (45a). Lubricating oil L is separated from the discharged, compressed refrigerant by an oil separator (80) and the lubricating oil L is supplied to the backside of a movable scroll (20) due to a pressure differential within the compress (1). After lubricating a bearing (10), the lubricating oil L is temporarily stored in the storage area (45a) and then is transferred due to a pressure differential to the suction-side of a compression mechanism (21) via the oil transfer route (4a). The lubricating oil L is then transferred to the oil separator (80) together with the compressed refrigerant that is discharged from a compression chamber (32) of the compression mechanism (21). Thus, the lubricating oil L contained in the discharged, compressed refrigerant can be effectively separated from the compressed refrigerant and circulated to and from the back side of the movable scroll (20) in order to lubricate moving parts within the compressor (1) using the pressure differentials within the compressor (1).

摘要： The pressure leakage from the back pressure chamber installed at the back side of the movable scroll to the low pressure area can be prevented. An eccentric shaft (17) formed integrally to a drive shaft (14) is inserted into a bushing (19). A balance weight (18) is fixed to the bushing (19). A cylindrical portion (34) is provided so as to protrude at the back side of the movable scroll base (22), and the bushing (19) supports the cylindrical portion (34) via a needle bearing (21). A seal member (35) is interposed between the end surface of the cylindrical portion (34) and the balance weight (18). The inside of a cylinder of the cylindrical portion (34) is made to be a back pressure chamber (36).
