Abstract: A scroll-type compressor assembly means has one or multiple positioning holes provided on a positioning post of the frame, and a positioning element to fix a retaining spacer to the frame for the retaining spacer to limit the stationary scroll and to define an ideal spacing between the positioning post and the stationary scroll; the ideal spacing not affected by the locking location of the positioning element to the positioning post that is far away from the ideal spacing or the stationery scroll for assurance of assembly quality of the compressor and prevention of operation noise or frustrated operation due to unpredictable change or narrowed ideal spacing between the positioning post and stationary scroll because that the positioning post is deformed.
