    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 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: An eccentric shaft 5 is radially slidably inserted in a bore 6a of a bushing 6, which is inserted in an opening 8c-1 of a boss portion 8c of a movable scroll member 8 by way of a radial needle bearing 7. An axial space 24 is confined between a rear end of a bushing 6 and a bottom surface of the opening 8c-1. The space 24 is in communication with the radial bearing 7 via an annular gap 26 between faced surfaces of bushing 6 and the opening 8c-1. A radial space 23 is confined between the inner surface of the bore 6a and the eccentric shaft 5, so that a limited radial movement of the eccentric shaft 5 with respect to the bushing 6 is allowed. A washer 21 for obtaining a fixed axial location of the bushing 6 on the eccentric shaft 5 is formed with recess 21b (first passageway 25) for communicating the radial space 23 with the axial space 24. The bushing 6 is further formed with a radial hole 27 (second passageway) for communicating the radial space 23 with a crank chamber R. A recirculation passageway for the lubricant is thus generated between the crank chamber R, the gaps in the needle bearing 7, the gap 26, the axial chamber 24, the first passageway 25, the radial space 23, the second passageway 27 and the crank chamber R.

    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 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 performance of a compressor is enhanced and durability of scroll bodies is enhanced by optimizing relief to machining tolerance at a central end part of spiral members for forming the scroll bodies. In a scroll type compressor in which a reinforced portion (for example, a large radius of curvature R) reinforced more than in other root corner portions 5 is provided in a root corner portion 5 at a central end part in which a stress of the two spiral members 10 and 20 is increased, a first relief is formed in a region in which the two spiral members 10 and 20 come into contact with each other where the reinforced portion is applied only to one of the spiral members 10 and 20, and a second relief larger than the first relief is provided in a region in which the two spiral members come into contact with each other at a portion in which the radius of curvature R is provided in both of the two spiral members, thereby reasonably forming reliefs for avoiding interference at the point of contact of two spiral members.
