    摘要: A scroll type compressor comprises a fixed scroll having an end plate and a spiral element. The spiral element of the fixed scroll is integrally coupled to the inner wall of a housing. A movable scroll has an end plate and a spiral element, and faces the fixed scroll, with a plurality of fluid pockets formed between the movable scroll and the fixed scroll. When the movable scroll makes an orbital movement around the axis of the rotary shaft, refrigerant gas is led into the fluid pockets from outside the movable scroll. As the fluid pockets move toward the center of the movable scroll the fluid pockets decrease in volume, thereby compressing the refrigerant gas. A suction chamber which receives the refrigerant gas from outside the housing is formed between the movable scroll and the inner wall of the housing. A passage is formed in at least one of the inner wall of the housing, the connecting section and the end plate of the movable scroll. This passage permits the refrigerant gas to flow into the fluid pockets from the suction chamber in order to reduce any difference in pressure of the refrigerant gas in the suction chamber and in the fluid pocket.

    摘要: A compressor has a fixed scroll and a movable scroll which has a first surface and a second surface. The first surface is opposed to the fixed scroll to define a displaceable fluid pocket. The movable scroll is supported on a rotary shaft via an eccentric pin to move along a predetermined orbit around an axis of the rotary shaft. Gas is introduced into and compressed in the fluid pocket. A boss is formed with the second surface of the movable scroll. A bushing is supported on the eccentric pin and rotatably received by the boss. The rotary shaft has an inner end surface for securely supporting the eccentric pin. A holding member engages the eccentric pin to hold the bushing in a predetermined position on the eccentric pin in corporation with the inner surface of the rotary shaft. A balance weight is secured around the bushing to cancel a dynamic imbalance of the movable scroll due to the orbital movement of the movable scroll.

    摘要: A large diameter portion of a rotating shaft is supported by an opening in a front housing via a radial bearing. An outer race of the bearing is in contact with an inner, rear surface of the housing as a shoulder portion of the opening. The inner surface is forwardly recessed, so that a small chamber is formed between the housing and the bearing unit. The housing has a stopper projection at a rear end of an opening to which a shaft seal unit is inserted. The projection is axially projected to a faced front surface of the large diameter portion of the shaft, while a seal chamber is formed between the shaft seal unit and the large diameter portion. The seal chamber is in communication with the small chamber. A plurality of circumferentially spaced grooves for holding lubricant are formed at the recessed surface for forming the small chamber.

    摘要: When a rotary shaft of a scroll type compressor rotates and a movable scroll of the compressor makes an orbital movement around the axis of a rotary shaft by way of an eccentric shaft, refrigerant gas is supplied to compression chambers between a fixed scroll and the movable scroll. A first bearing rotatably supports the rotary shaft. A second bearing is provided between the movable scroll and the eccentric shaft to permit relative movement therebetween. A balance weight attached to the movable scroll dynamically balances the movable scroll during its rotation. A crank chamber accommodates the balance weight. A suction port is so provided in the housing as to communicate with the crank chamber, and permits the refrigerant gas to be supplied into the housing. A passage is formed in the balance weight, the eccentric shaft and the rotary shaft to supply the refrigerant gas into a first gap between the first bearing and the rotary shaft and a second gap between the second bearing and the movable scroll.

    摘要: A compressor has a movable scroll supported on a bushing connected to a rotary shaft via an eccentric pin. The movable scroll and the bushing are disposed coaxial to the eccentric pin to rotate together with the eccentric pin. The movable scroll moves along a predetermined circular path around an axis of the rotary shaft to closely contact a fixed scroll, opposed to the movable scroll at a given portion to define a displaceable fluid pocket and compresses refrigerant gas introduced into the fluid pocket. The compressor comprises a first balance weight eccentrically supported on the eccentric pin for an integral rotation therewith. The first balance weight is arranged to generate first centrifugal force counteracting second centrifugal force generated in the movable scroll and the bushing based on the rotation of the movable scroll and the bushing. The first balance weight has a weight in a predetermined ratio to weights of the movable scroll and the bushing to cancel substantially 80 to 97 percents of the second centrifugal force with the first centrifugal force. Thus, the movable scroll is kept to move along the predetermined circular path.

    摘要: A movable scroll element for a scroll type compressor is produced by a combination of a mold casting process and a machining process. The mold casting process produces a cast product having an end-plate forming portion, a spiral-member-forming portion and a projecting portion for forming a drive power receiving portion. The cast product has an entire outer faces covered with black scale, and the machining process machines the end-plate-forming portion, a spiral member forming portion, the projecting portion by cutting. Nevertheless, at least an outer circumference of the drive power receiving portion, i.e., a boss portion of the movable scroll element is covered with an outermost layer consisting of black scale. Thus, a sufficient mechanical strength of the movable scroll element is obtained even if the wall thickness of the drive power receiving portion, i.e., the boss portion of the movable scroll element, is reduced.

    摘要: A compressor has a fixed scroll (2) and a movable scroll (9). Both scrolls (2), (9) have end plates (11), (13) and spiral elements (12), (14) integrated with their end plates (11), (13). Both scrolls (2), (9) engage with each other at the spiral elements (12), (14). Pockets (16-19) are formed between both spiral elements (12), (14). The pockets (16-19) move toward the centers of the spiral elements (12), (14) while their volumes are reduced in accordance with the revolution of the movable scroll (9), thus compressing refrigerant gas. Grooves (52), (50) are formed in end faces of the spiral elements (12), (14) of both the fixed and movable scrolls (2), (9). Fitted in those grooves (52), (50) are seals (53), (51) for securing airtightness with the mating end plates (12), (14). A height of at least one seal (53), (51) from the end face of the spiral element (12), (14) is set to a value for preventing peripheral end faces of the spiral elements (12), (14) from contacting the end plates (13), (11) of the mating scrolls (9), (8), with the movable scroll (9) inclined based on an assembling tolerance between the fixed scroll (2) and the movable scroll (9).
