SCROLL COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To solve problems of the oil feed groove provided in a crankshaft in a pressure-difference oil feeding method, wherein the groove is required to be small for enlarging the resistance and the groove inside is decompressed from a delivery pressure to an intermediate pressure and refrigerant included in lubricating oil is evaporated in a groove to cause oil shortage and cause abrasion and seizure of a shaft. SOLUTION: A hole for communicating an inside region with an outside region of an annular seal member is intermittently provided by a turning movement of a turning component as a restriction part in a surface in the back pressure chamber side of a turning mirror plate. A side channel lubricating oil path for feeding oil in a lubricating oil sump in the bottom part of the hermetically sealed vessel using a differential pressure between a hermetically sealed vessel pressure and the back pressure chamber is provided in a bearing sliding part and a connection part between the crankshaft and a turning spiral component.
