Abstract
The invention relates to an encapsulated refrigerator assembly of the type in which an integrated motor and compressor unit is resiliently mounted in a hermetically sealed casing or capsule. An oil sump at the bottom of the capsule is provided for lubricating oil. An externally disposed centrifugal separator with an oil collecting tank at the bottom thereof provides refrigerant in vapor form for the compressor and oil for the oil sump. The compressor has an inlet for receiving refrigerant vapor from the separator and the capsule has a single port connected to the separator. A connecting pipe inside the capsule provides fluid communication between the capsule port and the inlet of the compressor. Universal joint fittings at opposite ends of the connecting pipe allow for relative movement between the resiliently mounted motor compressor unit in the capsule and the relatively stationary capsule walls.
