PROBLEM TO BE SOLVED: To provide a double-ended piston compressor capable of reliably reducing vibration and noise during operation.SOLUTION: The compressor has a first cylinder block 15 formed with first cylinder bores 151-155, and a second cylinder block 17 formed with second cylinder bores 171-175. A first discharge chamber 27 is parted into first-fifth front side discharge sections 271-275 corresponding to the first cylinder bores 151-155, and a second discharge chamber 28 is parted into first-fifth rear side discharge sections 281-285 corresponding to the second cylinder bores 171-175. The first discharge chamber 27 is communicated with a first discharge passage 41 through the first front side discharge section 271, and the second discharge chamber 28 is communicated with a second discharge passage 43 through the third rear side discharge section 278. In the compressor, high-pressure refrigerant gas passing through each of the first and second discharge passages 41, 43 is joined into a joint part 39 to reduce rotation fourth-sixth order components.SELECTED DRAWING: Figure 4 |
