Abstract: It is assumed that a distance between a center portion of fixed scroll end plate and an outer peripheral portion at a distal end of fixed spiral wrap of fixed scroll is Ds, and that a distance between a center portion of orbiting scroll end plate and a portion included in a bottom face of an orbiting spiral wrap of orbiting scroll and facing the outer peripheral portion at the distal end of the fixed spiral wrap of the fixed scroll is Do. Further, assuming that an orbiting radius of orbiting scroll is ε, the orbiting radius being a distance between a center of eccentric shaft and a center of driving shaft, a relationship Ds+ε≤Do is satisfied.

Abstract: A refrigeration cycle device according to the present invention includes a compressor having a first compression chamber and a second compression chamber, a condenser, a decompressor, an evaporator, an injection path configured to introduce intermediate pressure refrigerant, a communication passage configured to introduce intermediate pressure refrigerant compressed in the first compression chamber to the second compression chamber, and a switch element configured to selectively make the second compression chamber communicate with the evaporator or make the second compression chamber communicate with the communication passage. The injection path introduces the intermediate pressure refrigerant to the second compression chamber. Single-stage compressing operation is performed when the second compression chamber is communicated with the evaporator, and two-stage compressing operation is performed when the second compression chamber is communicated with the communication passage.

Abstract: A scroll compressor according to the present invention includes a partition plate that partitions a sealed container into a high-pressure space and a low-pressure space, a fixed scroll adjacent to the partition plate, a orbiting scroll, a rotation restrictor, and a main bearing. The sealed scroll compressor further includes a pillar member having a lower end portion secured in a bearing-side engagement portion provided in the main bearing, and an upper end portion inserted in a scroll-side engagement portion provided in the fixed scroll. The axial distance from the upper end portion of the pillar member to the partition plate is smaller than the length by which the pillar member and the bearing-side engagement portion are coupled together.

Abstract: A scroll compressor includes partition plate (20) that partitions an inside of sealed container (10) into high-pressure space (11) and low-pressure space (12), and fixed scroll (30) adjacent to partition plate (20). The scroll compressor includes orbiting scroll (40) that meshes with fixed scroll (30) to form compression chamber (50), rotation restrictor (90) that prevents rotation of orbiting scroll (40), and main bearing (60) that supports orbiting scroll (40). Fixed scroll (30), orbiting scroll (40), rotation restrictor (90), and main bearing (60) are disposed in low-pressure space (12), and fixed scroll (30) and orbiting scroll (40) are disposed between partition plate (20) and main bearing (60). The scroll compressor includes bearing coupler (102) provided in main bearing (60), scroll coupler (101) provided in fixed scroll (30), and pillar member (100) having a lower end and an upper end, the lower end being inserted in bearing coupler (102) and the upper end being inserted in scroll coupler (101). A coupling region where pillar member (100) couples with scroll coupler (101) is in intersecting relationship with a horizontal plane positioned at a center of a scroll wrap height of fixed scroll (30).
