ABSTRACT:
A scroll type fluid displacement apparatus is disclosed having an adjustment mechanism for adjusting the axial clearance between the spiral elements and end plates of the fixed and orbiting scrolls. The apparatus includes a housing having a front end plate and a cup shaped casing attached thereto; the cup shaped casing has a fluid inlet port and a fluid outlet port. A fixed scroll, which includes a first end plate and a first spiral element, is fixedly disposed within the interior of the cup shaped casing. A large threaded opening is formed through an end plate of the cup shaped casing. An adjusting screw is screwed in the threaded opening to abut against the end surface of the fixed scroll. After adjusting the axial clearance between the fixed and orbiting scrolls by adjusting the position of the adjusting screw, a plurality of bolts fasten the fixed scroll to the cup shaped casing to prevent further axial movement. Therefore, the adjustment of the axial clearance between the scrolls is easily obtained by adjustment of the adjusting screw of the present invention.
