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 the piston part of a fixed shaft by means of a vane and compressing refrigerant gas by the change of volume. CONSTITUTION:When electricity is applied to a coil 13, a permanent magnet 12 rotates, and a lower bearing 11 to which the magnet is connected, a rotor 6, an upper bearing 7, a delivery valve 9 and a rotary yoke 10 rotate. And refregerant gas is sucked into the space of a piston part 2 through a suction port 3 and compressed by the volume change generated by the rotation of a vane. Accordingly a driving part can be provided along the periphery of a compression part and the device can be made compact. |
