    Abstract: Disclosed is a scroll type compressor including an orbiting scroll including an orbiting wrap and a fixed scroll including a fixed wrap, in which first and second oil channels are respectively constructed to supply oil to inner and outer oil channels formed by the orbiting wrap and the fixed wrap. Thus, the scroll type compressor has an oil channel structure that allows always-oil feeding into to the scrolls.
