Abstract
A motorcompressor comprising an electric motor, a load, a shaft assembly, the electric motor and the load being mounted on the shaft assembly, a casing configured to completely house the electric motor, the load and the shaft assembly for its entire length, a divider located in the casing to define a motor chamber and a load chamber, the divider comprising at least a pumping device configured to transfer a part of the fluid present in the motor chamber to the load chamber so as to obtain in the motor chamber a pressure that is lower than a pressure at a load inlet.

A motorcompressor comprising:
- an electric motor;
- a load;
- a shaft assembly, the electric motor and the load being mounted on the shaft assembly;
- a casing configured to completely house the electric motor, the load and the shaft assembly;
- and
- a divider located in the casing to define a motor chamber and a load chamber, the divider comprising at least a pumping device configured to transfer a part of a fluid present in the motor chamber to the load chamber so as to obtain in the motor chamber a pressure that is lower than a pressure at a load inlet, wherein the pumping device is an ejector, and wherein the ejector comprises a motive fluid nozzle fluidly connected to an inlet of the load or to a bleeding tap present at an upstream stage of the load.
