Abstract:
A refrigeration system with at least three compressors connected in a circuit. Each compressor has a housing with an oil sump. The oil sump is adapted to contain oil that defines an oil level. A supply line supplies refrigerant and entrained oil to each of the at least three compressors. The oil sump of each compressor has at least one oil port. Each oil port is disposed at an elevation that is equal to or minimally higher than the level of oil to promote equalization of oil levels in each compressor. There are a plurality of separate conduits which are not directly connected, but connected through the oil sumps of separate compressors. At least one compressor includes an oil sump extension having connections for the separate conduits. Each oil port is connected to the separate conduits or an oil sump extension. Each separate conduit connects a pair of compressors.

Claim (Index 1):
A refrigeration system comprising:\n at least three compressors connected in a fluid circuit, each compressor having a compressor housing having an oil sump in a lower portion thereof, the oil sump adapted to contain oil that defines an oil level when in a fully filled oil state; a supply line which supplies oil to each of the at least three compressors in any operating mode of the at least three compressors, wherein the oil sump of each compressor of the at least three compressors has at least one oil port in the lower portion, each oil port disposed at an elevation that is equal to or higher than the oil level of oil to thereby promote equalization of oil levels among the oil sumps; a plurality of separate conduits, wherein the separate conduits are not directly connected to other conduits, but are fluidically connected through the oil sumps of separate compressors of the at least three compressors; wherein one of the at least three compressors includes an oil sump extension having connections for at least one of the plurality of separate conduits, the oil sump extension configured to permit oil flow between oil sumps of compressors connected to the oil sump extension to promote equalization of the oil sump levels, and to prevent a flow of oil from bypassing any of the at least three compressors wherein each oil port is connected to one of the plurality of separate conduits or to the oil sump extension, each separate conduit connecting a pair of the at least three compressors.
