    Abstract: The compressor according to the compressor includes a sealed enclosure containing a compression stage, an electric motor having a stator provided with a first and second end windings, an intermediate casing surrounding the stator so as to define an annular outer volume with the sealed enclosure, connecting means arranged to fluidly connect the compression stage and a distal chamber defined by the intermediate casing and the electric motor and comprising the second end winding, and a refrigerant suction inlet emerging in the annular outer volume. The connecting means include at least one refrigerant circulation duct situated outside the intermediate casing, and at least one distal window formed on the intermediate casing and emerging on the one hand in the at least one refrigerant circulation duct and on the other hand in the distal chamber near the second end winding of the stator.
