PURPOSE:To obtain a small-sized compressor with low vibration by forming the rotor in an electrically driven part in a oylindrical shape and forming a compression part in the inside of the rotor. CONSTITUTION:A main shaft 7 is installed with both edges fitted slidingly to the bearings 10 and 11 arranged at the top and the bottom sides of a sealed vessel 2, and one edge of the main shaft 7 is so constituted as to be restricted from free rotation but allowed to make proper rotary vibration, through an elastic member 12. A rotor 3 is constituted to be revolved around a piston 8. While sliding on the bearings 10 and 11. Therefore, when an electric voltage is applied to the electrically driven part, a starting torque is generated by the interaction with the current generated by a stator 1, and a rotor outside cylindrical part 4 begins revolution. Following said revolution, a cylinder frame 5 also revolves around the piston 8, and an internal chamber 9 is divided into high and low pressure chambers by a vane 14, and coolant is gushed from a high pressure side to a tank internal chamber 13. |
