Abstract:
1. A scroll compressor, comprising: a fixed scroll having a fixed wrap; an orbiting scroll having an orbiting wrap engaged with the fixed wrap to form first and second compression chambers at an outer surface and an inner surface of the orbiting wrap, respectively, that performs an orbiting movement with respect to the fixed scroll; a rotational shaft having an eccentric portion, and an oil passage that extends in an axial direction, and combined with the orbiting scroll such that the eccentric portion overlaps the orbiting wrap in a radial direction; and a drive configured to drive the rotational shaft, wherein an oil hole is formed at the fixed scroll to supply oil inhaled through the oil passage of the rotational shaft to a thrust bearing surface of the orbiting scroll, wherein an outlet end of the oil hole is formed at the thrust bearing surface of the orbiting scroll, wherein when a line that connects a center of a compression chamber immediately prior to discharge to a geometric center of the orbiting scroll is referred to as a first reference line and a line that extends perpendicular to the first reference line at the center of the compression chamber is referred to as a second reference line, the outlet end of the oil hole is formed at a side of the second reference line at which the geometric center of the orbiting scroll is located.
