Abstract

A fixed scroll for a scroll compressor includes a plurality of pillar portions extending axially from a first face of the fixed scroll to an opposing second face thereof. Each of the plurality of the pillar portions is spaced radially outwardly of a spiral structure at least partially defining a compression chamber of the scroll compressor. The fixed scroll further includes an annular array of spaced flow openings into the compression chamber of the scroll compressor with each of the flow openings formed between adjacent ones of the pillar portions.
