Abstract
A scroll compressor has a sealed housing. Within the sealed housing is a first scroll member having a first base and a first generally spiral wrap extending form the first base. A second scroll member has a second base and a second generally spiral wrap extending from the base. The wraps of the first and second scroll members interfit to define compression chambers. A motor drives the second scroll member to orbit relative to the first scroll member. A valve controls the communication of gas between the compression chambers and a discharge pressure chamber. The valve is retained within a valve chamber of the first scroll member. A valve retainer is used to keep the valve within the valve chamber. The valve retainer is attached to the first scroll member by a snap fit connection.
