Scroll compressor

Abstract

A scroll compressor of simple structure and low production cost which can be protected when abnormal pressure state or abnormal temperature state of the compressor comprises: a sealed casing including a first chamber for forming a low pressure and a second chamber for forming a high pressure which are divided by a separating panel; a driving unit built in the casing for generating a driving force; a compressed unit connected to the driving unit via a rotating shaft for compressing and discharging fluid when the driving unit is operated; and a protecting device mounted on one side of the separating panel for bypassing the fluid of high pressure or of high temperature in the second chamber to the first chamber when a pressure difference or temperature difference between the first and second chambers is larger than a set value.
