<p>A scroll compressor (10) includes a high-pressure space (54) capable of communicating with a discharge port (32) and a back pressure space (56) capable of communicating with an intermediate port (33). A fluid passage (4) includes a seal ring (1) that closes the fluid passage (4) when the pressure of the back pressure space (56) is lower than that of the high-pressure space (54), and opens the fluid passage (4) when the pressure of the back pressure space (56) is higher than that of the high-pressure space (54).</p> |
