Abstract
In the hermetically sealed scroll compressor, an injection pipe for injecting a fluid to a compression chamber is connected to an injecting port of a fixed scroll. The injecting port includes a first injecting port which is provided in the vicinity of a fixed scroll inner curve and injects the fluid to an orbiting outer compression chamber, and a second injecting port 22b which is provided in the vicinity of a fixed scroll outer curve and injects the fluid to a orbiting inner compression chamber 8b. The second injecting port is placed in parallel in a radius direction with respect to the first injecting port and is placed so that an orbiting scroll wrap does not practically communicate with the orbiting outer compression chamber in the state in which the orbiting scroll wrap is in contact with the outer side of a fixed scroll wrap.
