(54) Title: APPARATUS FOR PREVENTING VACUUM OF SCROLL COMPRESSOR 1-536 1314 131a (57) Abstract: An apparatus for preventing vacuum of a scroll compressor, comprising: a fixed scroll (130) having a bypass hole (135) through which a suction chamber (51 ) of a casing (110) is connected to a discharge camber (52) of the casing (110); a valve ZZblock (151) having an inner channel through which the bypass hole (135) of the fixed scroll (130) is connected to the discharge Chamber (52) of the casing, and fixedly installed at the fixed scroll (130); and a valve member (152) disposed between the bypass C hole (135) of the fixed scroll (130) and the inner channel of the valve block (151 ), for opening and closing between the bypass hole '1(135) and the inner channel. Since the apparatus is assembled at an outer periphery of the fixed scroll (130), a processing error of the fixed scroll (130) is prevented thereby to reduce a production cost. Also, since foreign materials generated when a refrigerant channel Sis processed does not remain in a valve hole (155a), the valve member (152) is prevented form being mal-operated, a productivity is enhanced, and a fabrication cost is reduced.
