Abstract: A compressor is provided which is configured to allow lubrication of a thrust surface through an oil groove formed in a thrust surface of a fixed scroll. Also, a scroll compressor is provided which smoothly supplies oil to a thrust surface of a fixed scroll by including a fixed scroll having an oil groove formed in the thrust surface of a fixed scroll sidewall, and allows an injection pressure acting on an orbiting scroll in an upward direction to be added by supplying the oil guided to the oil groove to the thrust surface of the fixed scroll such that an overturn moment generated in the orbiting scroll may be offset.

Abstract: A scroll compressor is provided capable of supplying oil stored in an oil storage chamber upward through a rotary shaft to supply the oil to a compression device and to lubricate a bearing portion. The scroll compressor may include a casing, a drive motor, a rotary shaft, a main frame, a fixed scroll, and an orbiting scroll. A medium pressure chamber may be formed in or at a middle of the main frame, the fixed scroll, and the orbiting scroll. A pocket groove configured to guide oil discharged through the oil hole to the medium pressure chamber may be formed in an upper surface of the orbiting scroll, and a differential pressure path configured to guide the oil guided to the medium pressure chamber to the compression chamber may be provided in the fixed scroll.
