PURPOSE:To permit a large facility of a compressor to be highly developed by forming a plural pair of fluid passing through holes at the position closer to a center along a swirl from a fluid taking-in port on the side plate of a scroll member and increasing the capacity of the closed space formed between both swirl bodies. CONSTITUTION:Both fluid passing through holes 258 and 259 are formed outside, from the fluid passing through holes 255 and 256 formed beforehand, along the direction of a swirl, and at the position closer along the direction of the swirl from a fluid taking-in port. When a movable scroll member 26 is driven in the closed state of these passing through holes, namely in the nonexcited state of an electromagnet 43, fluid is introduced into the space formed between both swirl bodies 252 and 262 from the fluid taking-in port, and said fluid is compressed as the reduction of the volume of said space, reduces, and transferred to the center, and the compressed fluid is discharged into a chamber 321 from a discharge hole 254. As the initial volume of the closed space formed between both swirl bodies 252 and 262 is large, the compression ratio is increased, and a large facility of the compressor can be highly developed. |
