機。Two rotary compression elements 12 housed within the storage container 10.
13 are arranged in tandem with an intermediate partition plate 9 interposed therebetween, so that one drive shaft 1 drives each of the compression elements 12.13, and two compression elements 12.13 (7) suction port 16a, In a two-cylinder rotary compressor in which low-pressure refrigerant gas suction passages 11a and 16b are connected to the suction pipe 11, the suction passage of the compression element 13 on the downstream side of the low-pressure refrigerant gas flow is connected to the suction port 16b. A cylindrical slider 14 that is slidable in the longitudinal direction of this suction passage 11b and a shape memory alloy 15 that provides axial displacement to this slider 14 are housed in the shape memory alloy 11b.
The two-cylinder rotary compressor is characterized in that the slider 14 closes and opens the suction port 16b of the compression element 13 on the downstream side by expanding and contracting as a result of energization and de-energization.
