ABSTRACT:
A scroll-type fluid displacement apparatus comprises a housing having an inlet port and outlet port and a fluid displacement mechanism having a first end and a second end disposed within the housing for displacing a fluid from the inlet port to the outlet port. The fluid displacement mechanism is fixed to the housing by a plurality of fixing members. A discharge chamber is defined by the first end of the displacement mechanism and the housing. A matching surface is defined between the first end of the fluid displacement mechanism and the inner surface of the housing. A sealing device is disposed in the matching surface for sealing the matching surface between adjacent fixing members. Thereby, the scroll-type fluid displacement apparatus has superior axial sealing of the discharge chamber while simultaneously achieving simplifying manufacturing.
