摘要： A scroll type compressor includes a fixed scroll having a fixed spiral element and a fixed end plate, and an orbiting scroll is revolvable without rotating itself in opposition to the fixed scroll. The orbiting scroll includes an orbiting spiral element and an orbiting end plate. A plurality of compression chambers, of which volumes are decreased in response to the revolution of the orbiting scroll, are defined between the scrolls. A discharge port opens to the discharge chambers. The thicknesses of initiating sections of the fixed and orbiting spiral elements are designed larger than those of remaining sections thereof. Sealing members having a spiral shape are slidably interposed between the fixed and orbiting end plates of the fixed and orbiting scrolls, and the initiating sections of the fixed and orbiting spiral elements are in opposition to the respective end plates. The cross sectional area of an initiating section of the sealing member, which is integrally movable with at least the orbiting scroll, is larger than that of remaining section thereof. The sealing member is capable of covering a part of the discharge port.

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 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 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.

摘要： A first swash plate 18 is coupled to a drive shaft 16 to be rotatable integrally with the drive shaft 16. Single head pistons 23 are coupled to the first swash plate 18 via shoes 25A, 25B. Rotation of the drive shaft 16 rotates the first swash plate 18, which causes the pistons 23 to reciprocate and compress refrigerant gas. The first swash plate 18 supports an annular second swash plate 51 to be rotatable relative to the first swash plate 18 via a ball bearing 52. The second swash plate 51 is arranged between the first swash plate 18and the shoes 25B that receive a compressive load to be slidable with respect to the first swash plate 18 and the shoes 25B. Therefore, the first swash plate reliably slides with respect to the second swash plate.

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 compressor including a housing, a rotary shaft extending through the housing, and a sealing device arranged about the rotary shaft to seal the housing. A shaft bore extends through the housing for insertion of the rotary shaft. An elastomer lip ring seals the housing in cooperation with the rotary shaft, while contacting the peripheral surface of the rotary shaft in a slidable manner. A pressure resistant reinforcement arranged in the shaft includes a backup ring, which is arranged between the elastomer lip ring and the rotary shaft, and a stopper, which is fixed in the shaft bore. The backup ring contacts the elastomer lip ring. The stopper restricts movement of the backup ring in the axial direction relative to the rotary shaft and enables movement of the backup ring in a radial direction relative to the rotary shaft.
