PURPOSE: An enclosed compressor is provided to stably pump oil even at low-speed operation by pumping the oil using the viscous force of the oil. CONSTITUTION: An enclosed compressor comprises a sealed container, a screw shaft(42), a crank shaft(41), and a screw shaft support(44). The sealed container is filled with oil. The bottom of the screw shaft is submerged in the filled oil. A screw-shaped groove is formed on the outer surface of the screw shaft. A part of the screw shaft is inserted into the crank shaft. The screw shaft support is coupled to the bottom end of the screw shaft, and a part of the screw shaft support is submerged in the oil to prevent the screw shaft from becoming rotated. |
