Patent ID: 7559750

Claim:
An overheating protection apparatus of a scroll compressor having a discharge valve to permit gas to flow from a fixed scroll into a high pressure chamber, the overheating protection apparatus comprising: a bypass passage formed in the fixed scroll, the bypass passage connecting the high pressure chamber to a low pressure chamber; a valve assembly at least partially located in the fixed scroll, the valve assembly opening/closing the bypass passage, the valve assembly including: a valve housing formed in the fixed scroll and connected with the bypass passage; a valve body that is linearly movable installed at the valve housing, the valve body opening/closing the bypass passage; and a spring installed at one side surface of the valve body, for providing an elastic force to the valve body; and a heat distortion member configured to permit a flow of gas from the high pressure chamber through a separate passage to drive the valve assembly to open the bypass passage when a temperature inside the high pressure chamber rises more than an established value, wherein the bypass passage includes: a first passage connected between the high pressure chamber and the valve housing; and a second passage connected between the valve housing and the low pressure chamber, wherein the valve body is provided with a land portion having a smaller diameter in comparison with other portions of the valve body to connect the first passage and the second passage to each other, and wherein the heat distortion member is installed in a mounting groove formed at an upper surface of the fixed scroll, the mounting groove is connected to the separate passage opened/closed by the heat distortion member, and the separate passage is connected to the valve housing of the valve assembly.
