Abstract: A scroll compressor of the present invention includes a partition plate, a fixed scroll, an orbiting scroll, a rotation-restraining member, a main bearing, a discharge space, a ring-shaped first seal member and a ring-shaped second seal member. A pressure in the medium pressure space is set lower than that in the discharge space and higher than that in the low pressure space. The first seal member and the second seal member are sandwiched by the partition plate by means of a closing member, the fixed scroll can move in an axial direction of the fixed scroll between the partition plate and the main bearing. If a high pressure is applied to the discharge space, the fixed scroll can be pressed against the orbiting scroll.

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.

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).

Abstract: A turbomachine of the present disclosure includes a rotating shaft, an impeller, a bearing, and a casing. The casing is arranged around the impeller in a circumferential direction of the rotating shaft. A volute is defined in the casing as a passage of a working fluid that is compressed or expanded by rotation of the impeller. The casing includes one or more ribs. The one or more ribs are arranged only in a diagonal area, or the one or more ribs are a plurality of ribs and a degree of reinforcement of the diagonal area by the plurality of ribs is larger than a degree of reinforcement of a tongue portion area by the plurality of ribs.

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 rotary compressor (100) includes a closed casing (1), a cylinder (15), a piston (28), a lower bearing member (72), a vane (33), a suction port (20), a discharge port (41), and a partition member (64). The partition member (64) is attached to the lower bearing member (72) so as to form a space enclosed by the partition member (64) and the lower bearing member (72) at a position adjacent to the lower bearing member (72). A portion of an oil stored in the oil reservoir (22) flows into the enclosed space, and thereby an oil retaining portion (53) is formed. The oil retaining portion (53) is located on the same side as the suction port (20) with respect to a reference plane (H1).
