Abstract: A compressor unit having a triple trochoidal rotor, which includes a first rotor, a second rotor, a third rotor, a casing, second and first suction ports, and second and first discharge ports; and a driving unit that rotates the three rotors such that external working fluid is sucked into the suction port and the working fluid sucked into the suction port is discharged to the discharge port in a state of being compressed.

Abstract: A compressor unit having a gear rotor, and a compressor system using the same are provided. The compressor system includes a compressor unit having a triple trochoidal rotor, which includes a first rotor, a second rotor, a third rotor, a casing, second and first suction ports, and second and first discharge ports; and a driving unit that rotates the three rotors such that external working fluid is sucked into the suction port and the working fluid sucked into the suction port is discharged to the discharge port in a state of being compressed. The compressor unit may be constructed as a triple trochoidal rotor such that working fluid can be compressed in a two-stage compression manner to enable the working fluid to be supplied at high pressure and provide a high-speed, high-pressure compression capability.
