    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 mechanism for allowing the orbital movement of an orbiting scroll with respect to a fixed scroll in a scroll type compressor which prevents the orbiting scroll from rotating around its own axis is disclosed. The orbiting scroll is eccentrically attached to a rotary shaft supported by a housing that encases the fixed and orbiting scrolls. A compression chamber is defined by the interfitting between the orbiting scroll and the fixed scroll. During the course of the orbiting scroll's rotation around the center axis line of a rotary shaft, the volume of a compression chamber decreases as the rotation progresses. Refrigerant gas in the compression chamber is compressed in this manner as the constant volume of gas within the compression chamber decreases in size according to the progression of the rotating spiral member. A balancing weight disposed on the eccentric shaft compensates for dynamic unbalancing generated as the orbiting scroll makes an orbital movement due to the rotation of the rotary shaft. This balancing weight engages a bushing which supports the orbiting scroll. A mechanism for automatically adjusting the radius of the orbital movement is disposed between the rotary shaft and the balancing weight. A spring for restricting the shifting on the eccentric shaft of both the weight and the bushing in the thrust direction is disposed between the weight and the bushing.

    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： 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： In a variable displacement compressor of the invention, cylinder bores (111) and a crankcase (121) are formed in a housing, single-ended pistons (37) are fitted in the cylinder bores (111), and a cam plate (23) is provided in the crankcase (121). The displacement capacity of the compressor is varied by controlling the angle of inclination of the cam plate (23) in accordance with the difference between the internal pressure of the crankcase (121) and an suction pressure present on both sides of each single-ended piston (37). A dampening or muffler chamber (65) is provided downstream of an output channel (114) through which a refrigerant gas discharged from the cylinder bores (111) passes. A check valve (69) which opens and closes in accordance with a pressure difference between upstream and downstream sides of the output channel (114) is provided in the output channel (114), upstream of the muffler chamber (65). The present invention reduces the effects of pressure pulsations caused by the compression motion of the compressor and caused by the valve body of the open/close device hunting, has no bad effects on the external refrigerant circuit connected to the compressor, and increases the reliability of the lip seal.

    摘要： A variable capacity type compressor includes a swash plate and pistons to effect compressing action. The tilting position of the swash plate is controlled by the pressure in a control pressure chamber into which a coolant in the discharge pressure region is introduced. The pressure in the control pressure chamber is controlled by a capacity control valve mounted to the rear housing in an inclined position relative to a plane perpendicular to the axis of the rotatable drive shaft.
