To provide a scroll compressor having an overheating prevention device capable of increasing the reliability of the compressor by operating a valve assembly to open a bypass passage so as to bypass a high temperature and high pressure gas in a high-pressure chamber to a low pressure chamber for protecting the compressor when the temperature of the gas in the compression chamber is raised to a specified value or higher.
This scroll compressor having the overheating prevention device comprises a casing 10, a drive motor 12 incorporated in the casing 10 and generating a drive force, a compression unit 16 connected to the drive motor 12 and a rotating shaft and compressing a fluid when the drive motor 12 is driven to discharge the fluid to the outside, and the overheating prevention device 60 installed on one side of the compression unit 16, sensing the temperature of the gas compressed in the compression chamber of the compression unit 16, and when the temperature of the gas rises to a set value or higher, bypassing the high temperature and high pressure gas in the high-pressure chamber to the low-pressure chamber 22.
