摘要： 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.

摘要： A scroll compressor includes a pressing mechanism, a pushback mechanism and an adjustment mechanism. The pressing mechanism applies a pressing force toward a fixed scroll to the back side of an end plate portion of an orbiting scroll. The pushback mechanism applies a pushback force separating the orbiting scroll from a fixed scroll to the front of the orbiting scroll. The adjusting mechanism has a low-pressure portion filled with a fluid of a lower pressure than the discharge pressure of the compression mechanism, and a communicating groove formed in a sliding surface of an outer peripheral portion of the fixed scroll so as to communicate with the low-pressure portion in a first rotational angle range in order to reduce an upsetting moment of the orbiting scroll, and to be blocked from the low-pressure portion in a second rotational angle range other than the first rotational angle range.

摘要： A scroll compressor includes a compression mechanism having a fixed scroll and an orbiting scroll. The fixed scroll includes a first end plate, an outer peripheral wall extending from an edge of the first end plate, a first oil groove, and a first wrap inside of the outer peripheral wall. The orbiting scroll includes a second end plate in sliding contact with an end of the first wrap and an end of the outer peripheral wall, a second oil groove, and a second wrap. The first oil groove is disposed on a surface of the outer peripheral wall, extends along an inner periphery of the outer peripheral wall, and is configured to receive lubricating oil at a high pressure corresponding to a discharge pressure of the compression mechanism. The second oil groove is disposed on a surface of the second end plate, and is communicatable with the first oil groove.
