The utility model discloses a rotary compressor and have its refrigeration device. Rotary compressor includes at least one cylinder, base bearing, supplementary bearing, bent axle, piston and gleitbretter including sealed casing, compressing mechanism portion and fluid injection device, compressing mechanism portion, and every cylinder has relative two cylinder plane open -ended compression chamber. Every compression chamber corresponds one fluid injection device, and every fluid injection device includes: arbitrary cylinder plane open -ended valve pocket to the compression chamber, to valve pocket open -ended air vent hole, the air bleeding valve of the surface plate of switch air vent hole, to valve pocket sum -squeezing chamber open -ended exhaust passage, pour into the return circuit into with the refrigerant or the lubricating oil of air vent hole intercommunication, the off -centre operation synchro switch of air vent hole and piston. According to the utility model discloses a rotary compressor, fluid injection device's simple structure, fluid launching efficiency and reliability are high, have improved commonality and manufacturing nature.
