COMPRESSOR

This compressor is provided with: a compression mechanism (3) for compressing a refrigerant; a rotary shaft (6) that has formed therein an oil supply path (61) for supplying oil to a slide part including the compression mechanism; and a container that houses the compression mechanism and the rotary shaft and that has an oil reservoir (100a) formed at the bottom portion. Further, the compressor isprovided with: an oil supply pump (121A) that is driven by rotation of the rotary shaft so as to supply oil stored in the oil reservoir through the oil supply path of the rotary shaft; and an oil supply relief valve (125) that opens/closes an oil supply relief path (124b) through which the oil supplied from the oil supply pump through the oil supply path of the rotary shaft is partially released,and that opens when oil pressure in the oil supply relief path reaches a set pressure or higher. 压缩机具备：压缩机构(3)，对制冷剂进行压缩；旋转轴(6)，形成有向包括压缩机构的滑动部供给油的供油流路(61)；和容器，收纳压缩机构以及旋转轴，并在底部形成有储油部(100a)。并且，压缩机具备：供油泵(121A)，借助旋转轴的旋转来进行驱动，并将存留在储
