Abstract
A rotary closed type compressor is configured such that an inside of a case becomes high pressure, and the rotary closed type compressor comprises a first cylinder and a second cylinder having cylinder chambers in which eccentric rollers are housed, respectively, vanes which divide the cylinder chamber into two sections, respectively, and vane chambers in which back-face side end portions of the vanes are housed, respectively. The vane on the first cylinder side is pressed and biased by a spring member provided in the vane chamber, and the vane on the second cylinder side is pressed and biased according to pressure difference between case internal pressure introduced to the vane chamber and suction pressure or discharge pressure introduced to the cylinder chamber.
