摘要： A scroll compressor that includes a housing and scroll compressor bodies disposed in the housing as well as a method of operation thereof is provided. The housing is separated into different chambers by a separator. One of the scroll bodies is sealed to the separator with a floating seal arrangement including a seal interface between a floating seal of the floating seal arrangement and a hub of a fixed scroll compressor body. A seal retaining ring prevents axial motion of a seal member of the seal interface during start-up operations due to pressure imbalances across the seal member.

摘要： A scroll compressor includes a housing comprising a cylindrical shell arranged about a vertically-extending axis, and scroll compressor bodies, including a fixed scroll compressor body and a movable scroll compressor body. The scroll compressor bodies are disposed in the housing and have respective bases and respective scroll ribs that project from the respective bases and which mutually engage for compressing fluid. An electrical motor has a stator and rotor. There is a drive shaft and rotor that acts upon the drive shaft that acts upon the scroll compressor bodies to facilitate relative movement between the scroll compressor bodies. A separator plate is disposed in the housing to separate a high-pressure region from a lower pressure region. The separator plate has a central opening. A perimeter of the central opening is defined by a curved inner wall. The curved inner wall is joined to an outer wall via an annular plate.
