PURPOSE:To reduce the number of parts, facilitate the assmebling method, and reduce the size of a compressor having a motor-driven part and compressing elements by housing said compressing elements within a rotor which is a component of the motor driven part. CONSTITUTION:A stator 40, a component of the motor driven part, is shrinckage fitted to a container 57, to which a shaft 42 is fixed eccentrically. A rotor 41 is fitted to the shaft 42 and a vane 49 is retractably inserted into the groove 59 of the rotor 41 through a spring 48. With the shaft 42 made to serve as a lower bearing, a mating upper bearing 43 is fitted to the shaft with a bolt 44. When the rotor 41 rotates, the vane 49 travels, dividing a compressing chamber into a high pressure side 53 and a low pressure side 52. The refrigerant is fed through a suction pipe 46 and introduced from a suction port 51 into the inside of the low compressing chamber 52, in which it is compressed and discharged from an outlet port 50 to the inside of the container 57. Refrigerating machine oil is fed through a minute port 47 on the suction pipe 46, by means of the pressure difference between the suction and discharge pressures. |
