PURPOSE: An enclosed compressor and a refrigerator using the same are provided to prevent frictional noise and abrasion between a stator and a rotor by preventing a crank shaft from being bent while driving. CONSTITUTION: An enclosed compressor comprises a casing(100), a stator(210), a rotor(220), a crank shaft(230), a rolling piston(340), a cylinder(310), a vane(330), a first bearing(110), and a second bearing(120). The stator is fixed to the inner space of the casing. The rotor is rotatably arranged inside the stator. The crank shaft is coupled to the center of the rotor and pumps oil in the casing. The rolling piston is coupled to one end of the crank shaft. The cylinder accepts the rolling piston. The vane compresses a refrigerant with the rolling piston. The first bearing is coupled to the cylinder and supports one side of the crank shaft. The second bearing supports the other side of the crank shaft. |
