Claims

[Scope of utility model registration request]

A compression chamber is formed between a drive scroll which is pivotally supported by a casing and rotated by a driving means and a driven scroll which is also pivotally supported by a casing and rotates in mesh with the drive scroll, so as to discharge a pressure medium at a predetermined pressure. In the full-system rotary scroll compressor, the rotating shaft of the driven scroll and/or the driving scroll is formed of a hollow body, and a discharge pipe communicating with the discharge port of the compression chamber and the outside is disposed in the center thereof. a gap between the inner periphery of the rotating shaft of the hollow body and the outer periphery of the discharge pipe is communicated with a lubricating oil source, and an oil supply passage communicating with the gap and the compression chamber is provided inside. Features a full-system rotary scroll compressor oil supply structure.
