<p>A scroll-type fluid displacement apparatus, in particular, a compressor unit is disclosed. The unit includes a housing comprising of a cup-shaped casing (12) and a front end plate member (11) mounted on the casing to close its open end. A fixed scroll member with an end plate (251) and a spiral element (252) is formed with a plurality of legs (253) projecting from an end surface of the end plate opposite to an end surface from which the spiral element extends. An end surface of each leg is fitted against the inner surface of the cup-shaped casing and fixed by screws inserted from outside of the casing whereby the fixed scroll member is fixedly disposed within the housing. A seal ring (29) is disposed between an outer peripheral surface of the scroll end plate and the inner surface of the casing. An inner chamber of the casing is thereby partitioned into two chambers by the scroll end plate.</p> |
