摘要： A scroll type compressor which prevents occurrence of abnormally high pressures due to liquid compression at the time of startup so as to lighten the engine load by providing a projection on the end face of the shaft and a groove in which the projection fits in the end face of the bush supporting a movable scroll member, the projection and groove being arranged so that their abutting faces are inclined a predetermined angle with respect to a line connecting the center of the shaft and the center of the bush in the direction opposite to the rotational direction of the shaft and being positioned relative to each other so that the extension line of the abutting faces passes through the side opposite to the side where the center of the bush is positioned seen from the center of the shaft.

摘要： A scroll compressor having a driving shaft 6, on which a bushing 10 and a balancing weight 9 are supported. The drive shaft 6 includes, at its end, a drive projection 6a, which is engaged with a driven groove 10a formed in the bushing 10. A spring 20 is arranged between the drive projection 6a and the bushing 10 for urging the latter radially inwardly to reduce the radius of the orbital movement of the bushing 10. A centrifugal force generated in the bushing when the drive shaft 6 is rotated causes the bushing 10 to be moved radially outwardly to increasing the radius of the orbital movement of the bushing 10.

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： 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 scroll type compressor includes a front housing, a fixed scroll, a movable scroll and a rear housing, and its lateral cross section has a substantially oval shape. The spiral element of the movable scroll is located in the space defined by the front housing and the fixed scroll in such a way as to engage with the spiral element of the fixed scroll. The space defined by the fixed scroll and the rear housing serves as a discharge chamber where compressed refrigerant gas is discharged. Since this compressor has the same compression displacement as that of a compressor having a circular cross section, this compressor can be placed in narrow space whose width is less than the width of the circular compressor, without any reduction in the cooling performance.

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 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.
