Scroll type compressor apparatus with adjustable axial gap

A scroll type apparatus for fluid displacement, comprising:

• a housing, said housing including a plurality of bores, each of said bores extending axially through a portion of said housing;
• a first scroll having a base and rib portions;
• a second scroll having a second base and second rib portions, said rib portions of said first scroll and second scroll being shifted relative to one another to contact in a plurality of points to define, with said base of said first and second scrolls, at least one fluid chamber;
• a bearing disposed within the housing, said bearing including a plurality of bosses extending axially from said bearing and axially toward said plurality of bores, said bosses of said bearing being aligned with said bores;
• and
• a plurality of adjustment fasteners extending through said bores and in contact with said bosses to exert selective axial pressure against said bosses to reduce an axial gap between said first scroll and said second scroll.

• a shaft for driving said second scroll member into orbital movement relative to said first scroll member to move said fluid chamber;
• a bearing disposed within said housing having a surface and a plurality of bosses extending axially from said surface and toward said bores of said housing, said bosses being axially aligned with said bores;
• and
• an adjustment mechanism extending through said bores and configured to contact said bosses of said bearing to axially load said bosses.
