A machine for fluid transportation is provided. The machine includes a fluid displacement unit, a driving unit, a common shaft which transmits torque from the driving unit to the fluid displacement unit, a common casing, a suction line and a discharge line. The flow of the fluid is divided by at least one division unit into a primary flow to be pumped or compressed and a secondary flow which is lead to internal heat sources in the casing for cooling purpose by a conduction system. A throttling device is arranged in the suction line and the division unit is arranged upstream of the throttling device on the suction line, wherein the primary and second flows are reunited downstream the throttling device. |
