A refrigerating system in which a refrigeration fluid medium is flowing in a closed circuit comprising a compressor, a condenser, a receiver for containing the refrigeration fluid in a liquid state, and an evaporator serially connected between the outlet side and the intake side of the compressor; the improvement consisting in a cooling device for the compressor, comprising an auxiliary flow path for circulation of the refrigeration fluid, branched-off between the fluid receiver and the intake-side of the compressor and provided with a flow restrictor. Pressure sensing elements are provided on the intake side to provide a control signal in the absence of liquefied fluid in the receiver.
