Abstract:
An apparatus for preventing vacuum compression of a scroll compressor, comprising:a suction tube and a discharge tube each combined to a closed container; a fixed scroll having a wrap and a coolant inlet and an outlet; a high and low pressure separating plate fixed to an upper side of the fixed scroll so that relative movement between the fixed scroll and the separating plate is prevented, the separating plate dividing the inside of the closed container into a high pressure chamber and a low pressure chamber, the separating plate having a gas discharge hole therein; an orbiting scroll having a plurality of compressive chambers for compressing a sucked coolant by being rotatably engaged with the wrap of the fixed scroll at a lower side of the fixed scroll, and having a wrap for rendering each compressive chamber to be successively moved as the orbiting scroll is orbited; and a high vacuum preventing unit installed at the fixed scroll.
