Abstract (en)
A scroll compressor includes a through hole penetrating through a base plate portion of a fixed scroll to communicate with a compression chamber, a fixing part provided on a surface of the base plate portion that is opposite to an orbiting scroll to cover the through hole and having an injection port communicating with the through hole, an injection pipe being connected to the injection port, a valve body inserted into the through hole in such a manner that the valve body is configured to reciprocate, and a spring inserted into the through hole and configured to urge the valve body toward the injection port. A flow passage is formed in the valve body or between the valve body and the through hole and is configured to allow refrigerant having flowed into the through hole from the injection port to flow out to the compression chamber. The valve body is configured to close the flow passage between the injection port and the compression chamber when the valve body is urged by the spring to move toward the injection port.
