SCOROLL COMPRESSOR AND REFRIGERATOR HAVING THE SAME

摘要

PURPOSE: A scroll compressor preventing the efficiency decrease of a compressor due to the friction loss and a refrigerator in which the scroll compressor is applied are provided to increase the efficiency of a compressor by effectively preventing the friction loss. CONSTITUTION: A scroll compressor comprises a casing, a frame, a fixed scroll(40), and a rolling scroll. The casing has a sealed interior. A back pressure groove is formed at the edge of the frame. A wrap of helix is formed on one side of the fixed scroll. The rolling scroll is supported with the pressure of a back pressure groove in an axial direction while including the spiral wrap. The spiral wrap of the rolling scroll is meshed with the wrap of the fixed scroll and form a compression room. An oil supply hole(45) connected to an oil port is formed in the fixed scroll.
