Abstract:
A compressor that comprises a shell that forms an outer hull, a motor that is provided inside the shell, a shaft part that is attached to the motor and transmits rotational force from the motor, a fixed scroll that is fixed inside the shell and has a fixed locking part, an orbiting scroll that is connected to an upper end part of the shaft part, orbits due to the rotational force of the motor to form a compression chamber with the fixed scroll, and has an orbiting locking part, and an Oldham ring (15) that has a fixed-side engagement part that engages the fixed locking part and an orbiting-side engagement part that engages the orbiting locking part, is provided between the fixed scroll and the orbiting scroll such that the fixed-side engagement part and the fixed locking part are engaged and the orbiting-side engagement part and the orbiting locking part are engaged, and prevents autorotation of the orbiting scroll. A refrigerant channel (90) through which a refrigerant flows is formed at a ring-shaped part (15a) of the Oldham ring (15) that is between the fixed-side engagement part (15b) and the orbiting-side engagement part (15c).
