Abstract

A scroll compressor includes a fixed scroll and an orbiting scroll. Shapes of laps of the fixed scroll and the orbiting scroll are formed by an asymmetric tooth shape in which orbiting angles of an external line side compression room formed on an external line side of the orbiting scroll lap and an internal line side compression room formed on an internal line side of the orbiting scroll lap in finishing suction differ from each other. A communicating section control groove sets communicating sections communicating the respective inlet side openings of respective fluid outflow paths and a back pressure room. The communicating sections include a first communicating section of an internal line side compression room that is shorter than a second communicating section of an external line side compression room.
