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.

Abstract: A compressor is provided having an integrated flow path structure in which an oil flow path and an intermediate pressure flow path are integrated into one in a compression unit, thereby simplifying a flow path of the compression unit. The compressor may include at least one integrated flow path in which the oil flow path and the refrigerant gas flow are integrated into one in a fixed scroll. The at least one integrated flow path may connect an intermediate pressure chamber and a compression chamber in a compressors unit. The at least one integrated flow path may provide a compressed refrigerant in the compression chamber to the intermediate pressure chamber and provide oil in the intermediate pressure chamber to the compression chamber, simplifying the flow path of the compression unit.

Abstract: A scroll compressor is provided, that may include a connection groove to reduce discharge resistance. The scroll compressor may include a fixed scroll including a fixed end plate and a feed wrap and an orbiting scroll, rotating with respect to the fixed scroll and including an orbiting end plate and an orbiting wrap, and structure in which a connection groove having a concave groove shape provided at an inner surface of the fixed end plate to allow a refrigerant to flow through the connection groove depending on an overlapping state of the fixed wrap and the connection groove, thereby providing an effect of increasing opening efficiency of discharge holes at a beginning of discharge.
