Abstract:
A scroll compressor includes a high-pressure space capable of communicating with a discharge port and a back pressure space capable of communicating with an intermediate port. A fluid passage includes a seal ring that closes the fluid passage when the pressure of the back pressure space is lower than that of the high-pressure space, and opens the fluid passage when the pressure of the back pressure space is higher than that of the high-pressure space.
