Abstract: A scroll compressor is provided, in which a fixed side discharge opening is formed eccentric from a geometrical center of an orbiting scroll toward an orbiting side discharge opening, so as to overlap the orbiting side discharge opening across a relatively wide area. This may reduce flow resistance between the orbiting side discharge opening and the fixed side discharge opening. Accordingly, a refrigerant compressed in a final compression chamber may be rapidly discharged without being blocked by an upper frame, while maintaining a proper discharge pressure. Since uniform pressure may be maintained in compression chambers positioned at both sides of the scroll compressor, input losses due to over-compression may be reduced.

Abstract: A scroll compressor is provided that may include a casing; a discharge cover fixed to an inner space of the casing, that divides the inner space of the case into a suction space and a discharge space; a main frame in the casing, and spaced from the discharge cover; an orbital scroll that performs an orbital motion on the main frame; a non-orbital scroll coupled to the main frame so as to be movable up and down with respect to the orbital scroll, that forms a suction chamber, an intermediate pressure chamber, and a discharge chamber together with the orbital scroll; and a back pressure plate provided between the discharge cover and the non-orbital scroll, that forms a back pressure chamber that communicates with the intermediate pressure chamber. With such a configuration, a bypass valve may be easily installed, and application of an overload minimized.
