ABSTRACT:
A scroll compressor apparatus comprising a closed scroll compressor, an oil reservoir vessel separate from the closed scroll compressor, a discharge pipe, and an oil supply pipe. The closed scroll compressor includes a closed container having a suction port through which a compression medium is suctioned, a scroll compression mechanism encased in the closed container, a motor encased in the closed container, a first oil supply passage extending through an end plate of a fixed scroll and through which a first opening facing a sliding contact portion with an orbiting scroll is communicated with an oil supply port, a second oil supply passage formed in an end plate of the orbiting scroll and through which the first opening is communicated with a second opening facing an end face of a driving shaft, and a third oil supply passage, formed in the driving shaft, through which the second opening is communicated with the third opening facing a bearing supporting the driving shaft. A discharge port is provided on the closed container at a position opposite to the scroll compression mechanism unit with respect to the motor.
