A turbo compressor is disclosed. The compressor includes a hermetically sealed shell, a motor chamber formed at a center portion of the shell, a driving motor installed in the motor chamber, a driving shaft engaged with the driving motor having its one end inserted into a first compression chamber and its other end inserted into a second compression chamber with said first and second compression chambers being formed at both sides of the shell, first and second impellers disposed in the first and second compression chambers in a face-to-face form and rotatably engaged with both ends of the driving shaft, and a gas flow path through which a refrigerant gas is sucked for thereby first compressing the gas in the first compression chamber and discharging to the second compression chamber for thereby implementing a small size compressor, decreasing the number of parts and increasing a compression efficiency.

[ What is claimed is:] [1.] A turbo compressor comprising:a hermetically sealed container having a first compression chamber and a second compression chamber and having a discharge port fluidly connected to the second compression chamber, a motor chamber, a refrigerant gas suction port formed below the motor chamber and communicating with an evaporator and the motor chamber, a first gas flow path communicating with the motor chamber and the first compression chamber and a second gas flow path communicating with the first compression chamber and the second compression chamber;a driving motor disposed in the motor chamber;a driving shaft engaged with the driving motor and having one end inserted into the first compression chamber and a second end inserted into the second compression chamber;a first impeller disposed in the first compression chamber, rotatably engaged with the one end of the driving shaft, first compressing the suction gas introduced through the first gas flow path, discharging first compressed gas to the second compression chamber through the second gas flow path, and having a diameter in an inner diameter portion, where gas is introduced, smaller than a diameter in an outer diameter portion where the first compressed gas is discharged; anda second impeller disposed in the second compression chamber, rotatably engaged with the second end of the driving shaft, compressing for a second time the first compressed gas introduced into the second compression chamber and discharging twice compressed gas to the discharge port; andwherein the inner diameter portion of the first impeller faces an inner diameter portion of the second impeller.
