Patent attributes
Provided is an apparatus for preventing overheating of a scroll compressor including a first connection flow path for communicating a high pressure space and a low pressure space in a casing, a second connection flow path for communicating the first connection flow path and the low pressure space in the casing, a fluid refrigerant inflow guide pipe for guiding a fluid refrigerant from a refrigeration cycle system to flow into the low pressure space via the second connection flow path by connecting one side of the refrigeration cycle system with the second connection flow path, and a second connection flow path valve coupled to an inside of the first connection flow path, for opening/closing the second connection flow path according to a pressure difference between the low pressure space and the high pressure space, and a temperature sensing type valve coupled to an inside of the first connection flow path, for opening/closing the first connection flow path according to a temperature of the high pressure space, whereby the high temperature portion of the compressor is advantageously prevented from being overheated above a designated temperature while the compressor operates, and also manufacturing costs therefor are reduced.
