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, compress the sectioned refrigerant in a plurally of compression chambers, and discharge 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.

Abstract: A scroll compressor is provided, in which a balancing space may be formed on a sub frame to accommodate at least one balance weight, and an oil discharge hole may be formed on a main frame, thereby suppressing, all from being introduced into or remaining in the balancing space to minimize agitation loss due to oil agitation in the balancing space, and forming a thrust surface of the main frame adjacent to an axial center of the drive shaft to suppress axial leakage at a central portion of the orbiting scroll, reducing a size of the main frame to reduce a total weight of the compressor, facilitating a centering operation of the sub frame, and suppressing an outer diameter of the sub frame from being increased, thereby accomplishing miniaturization of the scroll compressor.
