Abstract

A scroll compressor is provided. The scroll compressor may include a case; a fixed scroll installed in the case; a wrap portion configured to form a compression chamber by being engaged with the fixed scroll; a base portion coupled to the wrap portion so as to be movable with the fixed scroll but not rotate in a circumferential direction; a drive motor coupled to a rear surface of the base portion, and configured to eccentrically rotate the base portion and the wrap portion; and a main frame installed in the case, and configured to support the base portion. A back pressure chamber that communicates with the compression chamber may be formed between the wrap portion and the base portion where a pressure of the back pressure chamber corresponds to a discharge pressure or an intermediate pressure between the suction pressure and the discharge pressure.

Description

technical field [0001] The present invention relates to a scroll compressor having a split type orbiting scroll, and in particular, to a scroll compressor capable of performing a compression operation when the orbiting scroll performs an orbiting motion relative to a fixed scroll. Background technique [0002] Generally, a scroll compressor is a compressor that compresses refrigerant gas by changing the volume of a compression chamber formed by a pair of scrolls facing each other. This type of scroll compressor is widely used in air conditioners because it has higher efficiency, less vibration, lower noise, smaller size, and lighter weight than reciprocating or rotary compressors. [0003] Such a scroll compressor may be classified into a low-pressure type and a high-pressure type according to a method of supplying refrigerant into a compression chamber. More specifically, the low-pressure scroll compressor is configured such that refrigerant is indirectly sucked into a com...
