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.
