摘要： Disclosed is a compressor which has a fixed scroll and a movable scroll. Defined between both scrolls is a compression chamber in order to provide compressed gas. A pressure receiving member receives compression reaction force of the compressed gas. A base plate is provided on the movable scroll. A turnable ring is disposed between the pressure receiving member and the base plate. The ring has the first and second surfaces respectively facing the pressure receiving member and the base plate. The first surface of the ring has a plurality of first elements circumferentially spaces and provided at predetermined intervals. A plurality of first recesses are provided in the pressure receiving member, with the first elements fitted into the first recesses respectively. The second surface of the ring has a plurality of second elements circumferentially spaced and provided at predetermined intervals. A plurality of second recesses are provided in the base plate, with the second elements fitted into the second recesses respectively. When the movable scroll revolves, the first and second elements move within the first and second recesses to prevent rotation of the movable scroll and the ring. To transmit the compression reaction force of the gas acting on the movable scroll to the pressure receiving member, the first and second surfaces of the ring are provided with a plurality of projections protruding toward the pressure receiving member and the base plate and having substantially spherical engagement surfaces to engage therewith.

摘要： A scroll type compressor has a movable scroll which is supported by a drive shaft by way of an eccentric pin in a housing. The movable scroll engages in an orbital movement for defining a compression chamber with a fixed scroll which is disposed opposite to the movable scroll. The compression chamber decreases in size in accordance with the orbital movement of said movable scroll for compressing gas in the compression chamber. A first ring orbits together with the movable scroll between the movable scroll and the housing, for receiving compressive reaction force acting on the movable scroll. A second ring which is secured to the housing receives the compressive reaction force received by and acting on the ring.

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： An improved scroll type compressor is disclosed. A moveable scroll is eccentrically connected to a rotary shaft and opposed to a fixed scroll for forming a compression chamber. The moveable scroll performs an orbital movement about an axis of the rotary shaft without rotating about its own axis. With the orbital movement, the moveable scroll reduces the volume of the compression chamber and compresses coolant gas therein. A fixed wall is disposed adjacent to the moveable scroll on the opposite side from the fixed scroll. The fixed wall receives a reaction force of the compressed gas applied to the moveable scroll. First elements disposed between the fixed wall and the moveable scroll transmit the reaction force from the moveable scroll to the fixed wall. Second elements are disposed independently from the first elements between the fixed wall and the moveable scroll for determining the orbit of the moveable scroll.

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).
