    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.

    IPC: F04C18/02

    Abstract: A scroll compressor is provided that may include a communication hole that penetrates from a side surface of a non-orbiting scroll adjacent to a discharge side to a thrust bearing surface between the non-orbiting scroll and an orbiting scroll, and a decompression member having a radial sectional area smaller than a radial sectional area of the communication hole and inserted into the communication hole. A refrigerant discharged to a discharge space may be introduced to a suction space through the passage between the communication hole and the decompression member, thereby preventing a high vacuum state of a compression chamber, and a refrigerant passing through the communication hole may be decompressed during a normal operation to restrain leakage of the refrigerant to the thrust bearing surface between the non-orbiting scroll and the orbiting scroll, thus increasing compression efficiency.

    Abstract: A scroll compressor is provided that may include a casing, an orbiting scroll and a non-orbiting scroll that suctions in a refrigerant from a suction space of the casing, compresses the suctioned refrigerant in a plurality of compression chambers, and discharges the compressed refrigerant into a discharge space of the casing, and a capacity varying device having a first valve and at least one second valve coupled with each other inside of the casing to selectively bypass a portion of the refrigerant in the plurality of compression chambers. With this structure, it is possible to prevent, in advance, refrigerant from being leaked outside of the scroll compressor, reduce pressure loss as a bypass flow path is shortened, reduce a size, weight, and manufacturing costs of the scroll compressor, and vary a capacity of the scroll compressor with a small operating force, and small power consumption.
