Abstract
A scroll-type fluid displacement apparatus includes a compressor housing, which contains a compression mechanism and a driving mechanism operatively connected to one another. The compression mechanism includes a fixed scroll and an orbiting scroll interfitting at angular and radial offsets, and a rotation preventing mechanism which prevents rotation of the orbiting scroll during its orbital motion. The driving mechanism includes a drive shaft axially disposed within the housing and rotatably supported by an inner block, which is fixedly disposed within the housing. An axial movement regulating mechanism for regulating an axial movement of the driving mechanism is disposed between the inner block and an internal component of the compressor axially spaced from the inner block. The regulating mechanism includes an annular flange extending from an exterior surface of the drive shaft and a shim which is detachably disposed either between the annular flange and the inner block or between the annular flange and the internal component.
