AXIAL PISTON COMPLIANCE IN SCROLL COMPRESSORS
|Owner||HITACHI-JOHNSON CONTROLS AIR CONDITIONING, INC. (Japan)|
AbstractIn some examples, a scroll compressor including an orbiting scroll and a fixed scroll includes a main frame that houses an axial cylinder to provide axial compliance between the fixed and orbiting scrolls. Intermediate pressure gas may be passed to a back chamber below the axial cylinder to provide an upward thrust force against the orbiting scroll plate. The axial cylinder may have a separate piston thrust plate. A counterweight and counterweight guide plate may be disposed within the axial cylinder to provide additional radial compliance.
