1. An oil supplying structure for a scroll compressor, comprising:
- a fixed scroll;
an orbiting scroll disposed adjacent to the fixed scroll to form a compression chamber therebetween; and
at least one oil hole formed in the orbiting scroll through which oil may be supplied into the compression chamber.

Abstract
A compressor and an oil supplying structure therefor are provided. When a compressor is operated at a high speed or low speed, a predetermined amount of oil is supplied to compression pockets formed between a wrap of an orbiting scroll and a wrap of a fixed scroll. Pressure leakage between the wraps may be prevented, thereby enhancing a performance of the compressor. Further, since friction between the orbiting scroll and the fixed scroll may be prevented, abrasion of the components may be minimized.

29. An oil supplying structure for a scroll compressor, comprising:
-
a fixed scroll; an orbiting scroll disposed adjacent to the fixed scroll to form a compression chamber therebetween; and a main frame having a bearing surface on which the orbiting scroll is supported, and a boss insertion groove into which a boss portion of the orbiting scroll is inserted, wherein at least one oil passage is formed in the main frame through which oil stored in the boss insertion groove is introduced between a disc portion of the orbiting scroll and the bearing surface of the main frame. - View Dependent Claims (30, 31, 32)

33. A method of supplying oil to a compression chamber of a scroll compressor comprising a fixed scroll and an orbiting scroll disposed adjacent to the fixed scroll to form the compression chamber, the method comprising:
-
providing at least one oil hole formed in the orbiting scroll through which oil may be supplied into the compression chamber; and positioning the at least one hole adjacent an oil passage formed in a bearing surface of a main frame that supports the orbiting scroll such that upon rotation of the orbiting scroll the at least one oil hole communicates with the oil passage to inject oil one of continuously or periodically into the compression chamber. - View Dependent Claims (34, 35)
