摘要： A scroll type compressor has a fixed scroll member, a movable scroll member, an oil reservoir, a back-pressure chamber, an oil extraction passage, a flow passage, and a partition wall. The back-pressure chamber disposed behind the movable scroll member is in communication with a discharge chamber. The oil extraction passage having a regulating valve or a throttle connects the back-pressure chamber to the oil reservoir. The oil return passage and the flow passage connect the oil reservoir to a suction chamber, respectively. The flow passage introduces excess lubricating oil into the suction chamber when the level of lubricating oil in the oil reservoir becomes higher than a predetermined level. The partition wall disposed between the openings of the oil extraction passage for restricting lubricating oil from the oil extraction passage other than the excess lubricating oil collected in the oil reservoir from flowing to the flow passage.

摘要： The scroll type compressor includes a stationary and orbiting scroll members, of which the spiral elements are interfit at an offset angle to form line contacts defining at least one fluid pocket, and an anti-spin mechanism for causing the orbiting member to orbit within the stationary member. A drive shaft is rotatably supported in a housing, and has an outer end a cylindrical inner end and, depending upon the embodiment, either a crank pin or a sliding guide portion projecting axially inward from its inner end. A drive bush couples the drive shaft to the orbiting scroll member, and has either a circular aperture for receiving the crank pin or an engaging slotted recess for receiving the sliding guide portion, as the case may be, whereby the drive bush is either pivotable or slidable with respect to the drive shaft. A counterweight is mounted on either the crank pin or the sliding guide portion between the drive bush and the drive shaft, and is coupled to the drive bush for conjoint movement therewith. The counterweight has a cylindrical recess for receiving the cylindrical inner end of the drive shaft, with a clearance maintained between the radially inner perimeter of the recess and the radially outer perimeter of the inner end of the drive shaft, so as to allow the drive bush and counterweight either to pivot relative to the crank pin or to slide relative to the sliding guide portion, depending upon the embodiment.

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 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).
