    Abstract: A scroll compressor includes a refrigerant suction pipe coupled to a discharge cover or a fixed scroll through a casing in a radial direction, a suction passage communicating the refrigerant suction pipe with a compression chamber, and a suction passage opening and closing valve disposed inside the suction passage to be slidable in an axial direction so as to selectively open or close the suction passage. Accordingly, when the compressor is stopped, oil or refrigerant in the casing can be restricted quickly so as not to flow back to the refrigerant suction pipe through a compression unit.
