PURPOSE:To contrive to make compact by rotating a lower bearing, a rotor and an upper bearing connected to a permanent magnet and enclosing a space to a piston part with a vane and compressing refrigerant gas by the volume change. CONSTITUTION:A permanent magnet 11 has a hollow cylindrical shape which has height larger than the difference between an outside diameter and an inside diameter and is fixed to a lower bearing 10. By the electricity application to a coil 12, the permanent magnet 11, the lower bearing 10, a rotor 6 and an upper bearing 7 connected to this rotate. And refrigerant gas is sucked into a space of a piston part 2 through a suction port 3 and compressed by the volume change caused by the rotation of a vane. Accordingly, a driving part can be provided at the periphery of a compression part and it is made possible to make compact. |
