Abstract
A check valve device is provided for a scroll compressor in which a crescent-shaped compression chamber is defined by a fixed scroll and an orbiting scroll, the orbiting scroll being driven to compress gas introduced into the compression chamber such that the compressed gas is discharged out of a discharge port provided in the vicinity of a center of the fixed scroll. The check valve device includes a check valve having a disk for closing the discharge port, a ring concentric with the disk and a plurality of beams coupling the disk and the ring, a tube receiving the check valve and which is provided at the discharge port of the fixed scroll, and a valve retainer for retaining the check valve. The valve retainer is provided at an outlet portion of the tube so as to confront the ring of the check valve.
