ABSTRACT:
An apparatus for preventing overheat of a scroll compressor comprising: an overload preventing device for connecting or cut off a power source by a temperature and a current; 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 located in the valve housing for increasing an input current by pushing the volume type valve and thus by blocking the discharge hole when temperature of discharge gas discharged to the discharge hole of the fixed scroll is more than a predetermined temperature. Accordingly, when a temperature of discharge gas is drastically or gradually increased and thus becomes a preset high temperature by several conditions at the time of driving the compressor, a driving of the overheated state is stopped by an immediate reaction thus to prevent a component damage.
