Title: Economizer/by-pass port inserts to control port size

Abstract: Compressor performance is affected by the size of an economizer or by-pass port area. To achieve variation in size, an insert is inserted into an economizer and/or unloader flow passage to provide a desired port area. The insert may be selected from a number of available insert sizes having different sized openings. In this way, a compressor designer can minimize machining time by keeping same flow passage geometry for different compressor sizes and applications.
