Abstract (en)
Provided is a scroll compressor with which it is possible to reduce damage in sliding sections, even under circumstances in which lubricating oil in a lower oil reservoir part has been depleted. This scroll compressor (1) has a volumetric pump (79) adapted to feed a lubricating oil to an oil feed passage (17a), in order to supply sliding sections above with lubricating oil stored in a lower oil reservoir part (P), via the oil feed passage (17a), which is disposed in a crankshaft (17). An oil retention space (90) is formed extending in an axial direction in the interior of the crankshaft (17), separately from the oil feed passage (17a).
