Abstract: A scroll compressor according to the present disclosure includes a partition wall that divides a sealed vessel into a high-pressure space and a low-pressure space, a non-orbiting scroll provided in the low-pressure space, an orbiting scroll that forms a compression chamber between the orbiting scroll and the non-orbiting scroll, and a rotational shaft. The scroll compressor further includes a main bearing that supports the orbiting scroll, an elastic body that biases one of the non-orbiting scroll and the orbiting scroll so as to separate the non-orbiting scroll and the orbiting scroll from each other, and a plurality of columnar members that are fixed at one ends of the columnar members and are movable at the other ends of the columnar members, and are disposed in a circumferential direction. The non-orbiting scroll or the orbiting scroll that is biased by the elastic body is movable between the partition wall and the main bearing in an axial direction of the rotational shaft. The elastic body is disposed between the plurality of columnar members in the circumferential direction.

Abstract: A scroll compressor of the present invention includes a partition plate 20, a fixed scroll 30, an orbiting scroll 40, a rotation-restraining member 90 and a main bearing 60. An inner wall of a fixed spiral lap 32 of the fixed scroll 30 is formed up to a location close to an ending-end of an orbiting spiral lap 42 of the orbiting scroll 40, thereby differentiating, from each other, a containment capacity of one (50A) of compression chambers and a containment capacity of the other compression chamber 50B, the fixed scroll 30 can move in an axial direction of the fixed scroll between the partition plate 20 and a main bearing 60, and high pressure is applied to a discharge space 30H formed between the partition plate 20 and the fixed scroll 30. According to this, the fixed scroll 30 can be pressed against the orbiting scroll 40.

Abstract: A scroll compressor of the present invention includes a partition plate 20, a fixed scroll 30, an orbiting scroll 40, a rotation-restraining member 90, a main bearing 60, a bearing-side concave portion 102, a scroll-side concave portion 101 and a columnar member 100. A lower end of the columnar member 100 is inserted into the bearing-side concave portion 102, and an upper end of the columnar member is inserted into the scroll-side concave portion 101. The columnar member 100 slides with at least one of the bearing-side concave portion 102 and the scroll-side concave portion 101, thereby moving the fixed scroll 30 in an axial direction between the partition plate 20 and the main bearing 60. A high pressure is applied to a discharge space 30H, thereby pressing the fixed scroll 30 against the orbiting scroll 40.
