Abstract

See full text

A scroll compressor may include an oil supply passage provided independent of an intermediate pressure chamber to allow an oil passage of a rotational shaft to communicate with a compression chamber, such that some of the oil suctioned through the oil passage is guided to the compression chamber. As an inner space of a casing communicates directly with the compression chamber without passing through the intermediate pressure chamber, even in a state in which an operating pressure ratio is, for example, 1.3 or less, namely, even if a differential pressure between the inner space and the compression chamber is not large, oil stored in the inner space may be smoothly supplied to the compression chamber.
