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 including a lubricating oil mist to be compressed. The movable scroll is revolved around a central axis of the immovable scroll so that, as the spaces are displaced toward a center of the immovable scroll, a volume thereof is reduced to compress the fluid therein. The immovable scroll has a passage through which each of the spaces is communicated with a discharge chamber upon reaching the center, whereby the compressed fluid is successively discharged through the passage into the chamber. An oil-separating plate is disposed in the chamber at a given level lower than the passage, and a reed valve is provided at the passage. A retainer for the reed valve is shaped such that the compressed fluid discharged from the passage through the reed valve is directed to and impinged on an upper surface of the plate, to thereby separate a lubricating oil from fluid, whereby the separated oil is reserved in a lower portion of the chamber defined by the plate, and thus a level of the reserved oil is maintained at the upper surface thereof.

摘要： An improved scroll type compressor having enlarged fixed and orbiting spiral element tips with parallel flat faces is disclosed. A discharge port for discharging compressed fluids is positioned in the fixed end plate. The discharge port is shaped to provide an opening that is effectively elongated adjacent the flat face of the fixed spiral element. In one preferred embodiment, the discharge port has a pair of elongated sides that extend in parallel with the flat face of the fixed spiral element. Another preferred embodiment the discharge port includes a plurality of holes arranged such that a common tangent to the perimeter of the holes is substantially parallel to the flat face of the fixed spiral element. A tapered surface may also be provided in the flat face of the enlarged tip of the orbiting spiral element to improve communication between the compression chamber and the discharge port.

摘要： A scroll type compressor comprising a stationary scroll member (2) and a movable scroll member (4) accommodated in a housing (10, 39), the scroll members (2, 4) being engaged with each other so that the movable scroll member (4) is subjected to an orbital motion around the stationary scroll member (2) and forms compression chambers (39) therebetween, in which chambers (39) a coolant gas is compressed by a volume reduction of the chamber (39) in accordance with the orbital motion, and is discharged therefrom to a refrigeration circuit. An intake port (8) for introducing the coolant gas into the housing (10, 30) is provided at a position closer to lubrication indispensable mechanisms such as a main bearing (32) or a sealing means (31) while confronting the periphery of a counterweight (35). The coolant gas is sucked into the interior of the housing (10, 39) and fed to the lubrication indispensable mechanisms (31, 32). When the counterweight (35) is positioned on the side closer to the intake port (8), the coolant gas is introduced directly therefrom to the compression chamber (39).

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： 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 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 scroll-type compressor having a unique coupling arrangement for driving the movable scroll is provided. The side of the base portion of the movable scroll opposite the spirals has a plurality of recesses disposed in a circular pattern. A support plate having a plurality of complementary recesses therein is positioned such that its recesses face the recesses in the movable plate. The diameters of the first and second recesses are different from one another. Coupling members are disposed between each facing pair of recesses. The coupling member has small and large diameter portions. The small diameter portion extends into its associated smaller recess while the large diameter portion extends into its larger associated recess. With this arrangement, the required width of the recess bearing portion of the support plate may be reduced relative to conventional designs which has several advantages.
