Abstract

A scroll compressor is disclosed. The scroll compressor may include an oil supply passage (190) provided independent of an intermediate pressure chamber (Sm) to allow an oil passage (126) of a rotating shaft (125) to communicate with a compression chamber (V), such that some of oil suctioned through the oil passage (126) is guided to the compression chamber (V). As an inner space of a casing (110) communicates directly with the compression chamber (V) without passing through the intermediate pressure chamber (Sm), even in a state where an operating pressure ratio is, for example, 1.3 or less, namely, even if differential pressure between the inner space and the compression chamber (V) is not great, oil stored in the inner space can be smoothly supplied to the compression chamber.
