PROBLEM TO BE SOLVED: To smoothly supply refrigerating machine oil to a sliding part, even when a compressor is operated in an inclined state, in the horizontal type multi-stage compression rotary compressor of a so-called internal intermediate pressure type.;SOLUTION: A sealed vessel 2 houses a rotary compression mechanism part 10 constituted of a first-stage compression element 20 and a second-stage compression element 40 and an electric motor 3 driving the rotary compression mechanism part 10, and has a bottom part used as an oil reservoir part 2a. The sealed vessel 2 has a baffle plate 70 therein dividing the sealed vessel 2 into two sections of a compressor chamber 81 housing the rotary compression mechanism part 10 and an electric motor chamber 82 housing the electric motor 3. The baffle plate 70 is in a shape of a cup constituted of a disc partition part 71 and a wall part 72 extending from the partition part 71 to an electric motor 3 side, and a clearance part 73 is formed between the wall part 72 and an inner face of the sealed vessel 2. Gas discharged from the first-stage compression element 20 is exhausted to the electric motor chamber 82, and gaseous cooling medium of the intermediate pressure flowing from the electric motor chamber 82 to the compressor chamber 81 is taken into the second-stage compression element 40.;COPYRIGHT: (C)2005,JPO&NCIPI
