Abstract
A check valve retainer for a scroll compressor includes a retaining lip that fits into a recess formed in a scroll. The retaining lip may be manufactured as an integral part of the check valve retainer for press fitting or may be formed by an expansion fit locking member having a protrusion that forces a portion of check valve retainer wall into the recess. The retaining lip ensures that the check valve retainer stays attached to the scroll without risking scroll deformation.
