Abstract (en)

[origin: US2020166250A1] In order to improve a refrigerant compressor, in particular for a refrigeration system, including a common housing, a compressor unit arranged in the common housing, a mechanical compressor drive unit for the compressor unit, arranged in a drive chamber of the common housing, a lubricant bath forming in the drive chamber, an intake duct that extends in the common housing in a manner separated from the drive chamber and through which the compressor unit draws in by suction refrigerant that is to be compressed, such that a refrigerant compressor is provided in which the spurting of lubricant is reduced to the greatest possible extent, it is proposed that that the intake duct and the drive chamber should be connected by way of a gas equaliser duct, which allows a permanent equalisation of gas between them, and which has on one side an opening on the drive chamber side and on the other an opening on the intake side, and of which the duct length between the openings corresponds to at least twice an equivalent duct diameter, in particular a smallest equivalent duct diameter, of the gas equaliser duct.
