SCROLL COMPRESSOR

摘要

PURPOSE: A scroll compressor is provided to improve a performance by suppressing a refrigerant temperature rising of a suction chamber by installing a minute flow path for a pressure control of a back pressure chamber. CONSTITUTION: A scroll compressor comprises a housing (10), a rolling scroll (32), an ejection chamber (70), and a back pressure chamber (80). The housing accommodates a driving unit (20) including a stator (21), a rotor (22), and a rotary shaft (23). In the housing, a suction chamber (50) inhaling a mixture fluid including a refrigerant and an oil is formed in an inside. The rolling scroll forms a fixed scroll (31) fixed inside the housing and a compression chamber (60) by engaging the fixed scroll by circling by a rotary shaft of the driving unit. The ejection chamber discharges the mixture fluid compressed in the compression chamber. The back pressure chamber is provided with the mixture fluid from the ejection chamber in order to add a pressure to stick the rolling scroll to the fixed scroll. A flow path (100) which controls a pressure of the back pressure chamber by communicating with the suction chamber is installed inside the housing.
