The separating device according to the invention comprises a body delimiting a separating chamber, at least one inlet orifice emerging in the separating chamber and intended to be connected to a discharge orifice of the refrigerant compressor so as to allow a lubricant-refrigerating gas mixture to be introduced into the separating chamber, at least one lubricant outlet orifice emerging in the separating chamber and intended to be connected to a lubricant pan formed in the refrigerant compressor. The separating device comprises a first measuring means arranged to measure the temperature of the lubricant contained in the lubricant pan formed in the refrigerant compressor, and a regulating means arranged to regulate the temperature of the lubricant separated in the separating chamber as a function of the temperature of the lubricant measured by said first measuring means.

Device for separating lubricant from a lubricant-refrigerating gas mixture discharged from at least one refrigerant compressor

This refrigeration compressor includes a plurality of compression units, each compression unit having a cylinder head including a refrigerant suction chamber and a refrigerant discharge chamber, a refrigerant distribution device having a distribution pipe and bypass pipes putting the distribution and the suction chambers of the compression units in communication, and a refrigerant discharge device having a discharge pipe and bypass pipes putting the discharge pipe and the discharge chambers of the compression units in communication. The compressor also includes a pressure equilibration pipe arranged to put the suction chambers of at least two compression units and/or the discharge chambers of at least two compression units in communication.
