(54) Hermetic compressor


(57) A cooling system for an electric compressor for vehicle use is disclosed. The system comprises an electric compressor having a motor housed within a closed container and a compression element driven by said motor which compresses a refrigerant gas drawn from the exterior of said closed container and thereafter discharges it to the exterior of said closed container, and heat exchanging means arranged to establish a heat exchanging relationship with an engine cooling system of the vehicle. The refrigerant gas discharged from said compression element flows to said heat exchanging means and returns to the said motor side within said closed container and thereafter is discharged to the exterior of said closed container.
