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).

Abstract: A scroll compressor includes a pillar-shaped member that is inserted into a scroll-side engagement section formed on a stationary scroll. A lower end-face of an engagement section between the pillar-shaped member and the scroll-side engagement section is located above a lap end-face of a stationary spiral lap.

Abstract: A sheet-shaped check valve which opens and closes the injection passage is placed in the check valve chamber, an injection discharge passage portion connected to the compression chamber of the injection passage and the check valve chamber open from an outer surface of the fixed scroll, a lid body is attached to openings of the injection discharge passage and the check valve chamber such that the check valve is sandwiched between the openings and the lid body, and the injection discharge passage and the check valve chamber are hermetically closed, thereby forming the injection passage. According to this, it is possible to provide a reliable, efficient and inexpensive compressor with an injection mechanism.

Abstract: An elastic body is provided which biases one of a fixed scroll and an orbiting scroll in a direction in which the fixed scroll and the orbiting scroll are spaced away from each other. With this, upon the start-up of a compressor, a gap is formed between the fixed scroll and the orbiting scroll, and thus the startability is improved.

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.
