摘要：PURPOSE:To increase the capacity efficiency and prevent overcompression by fixing a compression element directly connected to a motor onto a chamber and installing the discharge chamber for one or both of the contiguous compression elements between them. CONSTITUTION:A between-cylinder-discahrge chamber 32 which communicates to the discharge chamber for the upper compression element 33a and for the lower compression element 33b is installed between the lower bearing 27c for the upper cylinder and the upper bearing 28d for the lower cylinder, and an upper discharge valve 21a and a lower discharge valve 21b are arranged in the between-cylinder discharge chamber 32, and a discharge passage 37 which communicates to the discharge chamber 32 is provided with. The compression element which is closest to a motor and directly coupled with the motor is fixed onto a chamber, and the discharge chamber for one or both of the contiguous compression elements is installed between the contiguous compression elements. Therefore, a plural-cylinder rotary compressor which is free from reduction of the capacity efficiency and overcompression can be obtained at a low cost.
