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 compression chamber includes the compression chamber partitioning member, an intermediate pressure chamber guides an intermediate pressure working fluid before injection to the compression chamber, and the intermediate pressure chamber and the compression chamber face each other with a compression chamber partitioning member interposed between the intermediate pressure chamber and the compression chamber. Further, the intermediate pressure chamber includes an intermediate pressure chamber inlet through which an intermediate pressure working fluid flows, an injection port inlet of an injection port through which the intermediate pressure working fluid is injected into the compression chamber, and a liquid reservoir formed at a position below the intermediate pressure chamber inlet, and the liquid reservoir is formed by the compression chamber partitioning member.

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 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 compressor uses a refrigerant containing R1123 (1,1,2-trifluoroethylene) as a working fluid, and uses a polyvinyl ether oil as a compressor lubricating oil. In addition, a fixed scroll (12) and a revolving scroll (13) each having a spiral lap rising from an end plate, and a compression chamber (15) which is formed by meshing the fixed scroll (12) and the revolving scroll (13), are provided. In addition, a discharge hole (18) which is provided at a center position of the end plate of the fixed scroll (12), and is open to a discharge chamber (31), a bypass hole (68) which is provided in the end plate of the fixed scroll (12), and communicates with the compression chamber (15) and the discharge chamber (31) at a timing different from a timing at which the compression chamber (15) communicates with the discharge hole (18), and a check valve which is provided in the bypass hole (68), and allows a flow from the compression chamber (15) side to the discharge chamber (31) side.
