Abstract
Provided is an overheating protection apparatus of a scroll compressor which comprises: a bypass passage formed in a fixed scroll, for connecting a high pressure chamber to a low pressure chamber; a valve assembly installed on the bypass passage, for opening/closing the bypass passage; and a heat distortion member for bypassing gas of high temperature and high pressure inside the high pressure chamber to the low pressure chamber by driving the valve assembly toward a direction of opening/closing the bypass passage when a temperature inside the high pressure chamber rises more than an established value. According to this, when a discharged gas rises to an abnormal high temperature, gas inside the high pressure chamber is bypassed to the low pressure chamber, thereby protecting the compressor and also improving reliability thereof.
