<p>PROBLEM TO BE SOLVED: To provide a scroll compressor capable of suppressing back-flow of lubricant through an oil return flow passage, even in a case where the oil return flow passage is provided so as to avoid a state where lubricant is accomplished by discharging refrigerant.SOLUTION: A scroll compressor 1 includes a casing 10, compression mechanism part 15, a crank shaft 17, a crank chamber 31, a motor 16, an oil return flow passage 6, and a pressure equalizer 90. The oil return flow passage 6 extends so as to connect between the crank chamber 31 and a lower oil reservoir part P while ensuring sealability. The pressure equalizer 90 connects the crank chamber 31 to a high-pressure space 18 in the casing 10 and on the discharge side of the pressure mechanism part 15.</p> |
