<p>PROBLEM TO BE SOLVED: To provide a scroll compressor capable of suppressing lubrication oil supplied to a slide portion from flowing out together with refrigerant to be discharged to the outside of a casing when the lubrication oil is returned to a lower oil reservoir.SOLUTION: A scroll compressor 1 includes a positive displacement pump 79 for feeding lubrication oil stored in a lower oil reservoir P into a first oil supply path 17a provided on a crankshaft 17 so as to supply the lubrication oil to an upper slide portion via the first oil supply path 17a. The first oil supply path 17a extends so as to communicate with a pin-shaft upper space 37 without an opening penetrating toward a lower bearing 27, and a pin-bearing oil-supply cave hole 17c for supplying the lubrication oil to the slide portion diverges from the first oil supply path 17a. A second oil supply path 90 extends, apart from the first oil supply path 17a, axially downward from the pin-shaft upper surface 37. A lower-portion bearing oil-supply cave hole 17d extends so as to penetrate from a portion near a lower end of the second oil supply path 90 to an inner circumference of the lower bearing 27.</p> |
