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 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 discharge space 30H, a ring-shaped first seal member 141 and a ring-shaped second seal member 142. A pressure in the medium pressure space 30M is set lower than that in the discharge space 30H and higher than that in the low pressure space 12. The first seal member 141 and the second seal member 142 are sandwiched by the partition plate 20 by means of a closing member 150, the fixed scroll 30 can move in an axial direction of the fixed scroll between the partition plate 20 and the main bearing 60. If a high pressure is applied to the discharge space 30H, the fixed scroll 30 can be pressed against the orbiting scroll 40.

Abstract: A sheet-shaped check valve 23 which opens and closes the injection passage 21 is placed in the check valve chamber 22, an injection discharge passage 21b portion connected to the compression chamber 13 of the injection passage 21 and the check valve chamber 22 open from an outer surface of the fixed scroll 11, a lid body 25 is attached to openings of the injection discharge passage 21b and the check valve chamber 22 such that the check valve 23 is sandwiched between the openings and the lid body 25, and the injection discharge passage 21b and the check valve chamber 22 are hermetically closed, thereby forming the injection passage 21. According to this, it is possible to provide a reliable, efficient and inexpensive compressor with an injection mechanism.
