Abstract:
1. An apparatus for preventing overheat of a scroll compressor comprising a hermetic container, a frame fixedly coupled to inside of the hermetic container, a driving motor provided with an overload preventing device for connecting or cutting off a power source by a temperature and a current and fixedly coupled to inside of the hermetic container, a fixed scroll provided with a discharge hole for discharging gas and coupled to the frame, an orbit scroll orbit-movably coupled to the fixed scroll, and a crank axis for transmitting a driving force of the driving motor to the orbit scroll, the apparatus comprising: a valve housing formed as a predetermined shape and fixedly coupled to the fixed scroll; a volume type valve movably inserted into the valve housing for opening and closing the discharge hole of the fixed scroll; and a valve pressurizing means comprising a thermal valve located in the valve housing where discharge gas flows for closing a hole of the valve housing for increasing an input current by pushing the volume type valve and thus by blocking the discharge hole based on temperature of discharge gas discharged to the discharge hole of the fixed scroll being more than a predetermined temperature.
