An integral compressor-expander is disclosed. The integral compressor-expander of the present invention comprises: a cylindrical case; a motor installed inside the case and rotating a crank shaft; a vane expander wherein a rotor is coupled to a side of the crank shaft and rotates by a force of a fluid; and a rotary compressor installed between the motor and the vane expander and compressing a fluid as a roller coupled to the other side of the crank shaft rotates. A rotational force of the rotor is transmitted to the roller via the rotation of the crank shaft and reduces the power required for the rotation of the rotary compressor. According to the present invention, as the rotor of the vane expander is coupled to a concentric portion and the roller of the rotary compressor is coupled to an eccentric portion of the crank shaft, the rotational force of the rotor is directly transmitted to the roller via the rotation of the crank shaft for a liquid fluid to flow into an expander like refrigerating cycle. Although a gaseous fluid flows into the compressor to make an imbalance in the volume flow rate between the expander and the compressor, the integral compressor-expander smoothly operates without the installation of an additional compressor. |
