PURPOSE:To prevent heating of intake refrigerant gas, by a method wherein a cover pipe is secured to the outside of a suction pipe in a state to form a space, and the cover pipe is airtightly secured, in a position closer to a compression element than that of a vent hole, to a closed container. CONSTITUTION:A compression element 14 is secured to a closed container 11, and a rotor 15, with which a motor-operated element 12 is formed, is secured to a crank shaft 16. A cover pipe 19 is secured to a suction pipe 17 in a state to form a space 19c, and a closed container 11 is airtightly secured, in a position further close to the compression element 14 than that of a vent hole 19b, to the cover pipe 19. Transfer of heat to refrigerant gas in the suction pipe from high temperature high pressure gas in a closed container can be decreased, and intake refrigerant gas can be prevented from being heated. |
