Abstract
A scroll compressor, and more particularly, to a scroll compressor including a communication groove which may decrease discharge resistance is provided. The scroll compressor may include a fixed scroll having a fixed end plate and a fixed wrap, and an orbiting scroll configured to perform an orbiting movement about the fixed scroll and having an orbiting end plate and an orbiting wrap. A communication groove in the form of a recessed groove may be formed in an inner surface of the orbiting end plate, and a refrigerant may flow through the communication groove according to a state in which the fixed wrap overlaps the communication groove such that there is an effect in that an opening efficiency of a discharge hole is improved at an initial stage of discharge.
