ABSTRACT:
A refrigerant compressor system suitable for transport refrigeration applications, including a refrigerant compressor, an electric motor and a hydraulic motor directly coupled together within a common housing. The electric motor includes a stator and a rotor, with the rotor having first and second axial ends. The refrigerant compressor is coupled to the first axial end of rotor, and the hydraulic motor is coupled to the second axial end. A single housing surrounds the electric motor, the refrigerant compressor, and the hydraulic motor. Hydraulic fluid for driving the hydraulic motor is selected to be compatible with the lubricating oil of the refrigerant compressor, such that leakage of hydraulic fluid into the housing will not adversely affect operation of the refrigerant compressor system. The housing is directly connected to a selected side of an associated refrigeration system, with the suction side being preferred, enabling the housing to also function as a refrigerant accumulator.
