Abstract
A scroll compressor includes a flow path guide disposed between a motor unit and a compression unit to separate a refrigerant flow path and an oil flow path. A guide discharge hole communicating with a discharge passage of the compression unit is formed axially through the flow path guide and a guide passage communicating with the guide discharge hole is annularly defined, such that a discharge guide protrusion surrounding the guide discharge hole extends toward the motor unit. Accordingly, inner and outer spaces of the flow path guide can communicate with each other while the refrigerant flow path and the oil flow path are separated, which results in securing a space of an oil recovery passage to allow quick oil recovery and simplifying a structure of the flow path guide to reduce manufacturing costs.
