Provided are a compressor which requires no supply of oil in each compression stage and in which no lubricating oil is mixed into a gas that has passed through the final compression stage, and an LNG tanker equipped with the compressor. In the compressor 1, a gas supplied from an intake opening 3 is compressed in one or a plurality of compression stages 9, 10, 13, 14, 15 and then delivered via an ejection opening 7, wherein cylinders 11, 12, 16, 17, 18 in the one or plurality of compression stages 9, 10, 13, 14, 15 do not require supply of oil in all of the compression stages, and at least the cylinder 11, 12, 16, 17, 18 in the final compression stage 9, 10, 13, 14, 15 is cooled by circulation of a cooling fluid in a flow passageway provided in a cylinder liner 35.

    本发明提供一种在各压缩级均不需要供油且经过最终压缩级之后的气体中不混入润滑油的压缩机及搭载有该压缩机的LNG船。使从吸入口(3)被供给的气体在一个或多个压缩级(9、10、13、14、15)中进行压缩并从排出口7送出的压缩机1中,所述一个或多个压缩级(9、10、13、14、15)的气缸(11、12、16、17、18)在全部压缩级中均不需要供油,通过设置在气缸套(35)内的流路内的冷却液的回流对至少最终压缩级(9、10、13、14、15)的气缸(11、12、16、17、18)进行冷却。
