SCROLL COMPRESSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18149973 titled 'SCROLL COMPRESSOR

Simplified Explanation

The abstract describes a scroll compressor that includes an oil supply hole and an oil supply groove on the outer surface of a rotating shaft.

• The oil supply hole allows oil to flow from an oil passage to the outer surface of the rotating shaft.
• The oil supply groove is connected to the oil supply hole and is located along the outer surface of the rotating shaft.
• The oil supply groove is spaced apart in multiple locations along the rotating shaft.
• This design prevents the oil supply groove from interfering with the oil film section and increases the centrifugal force on the oil in the groove.
• As a result, friction loss and wear between the main frame and the rotating shaft are reduced.

Original Abstract Submitted

A scroll compressor is disclosed. The scroll compressor may include an oil supply hole penetrating from an oil passage to an outer circumferential surface of a rotating shaft, and an oil supply groove communicating with the oil supply hole and formed along the outer circumferential surface of the rotating shaft. The oil supply groove may be provided in plurality axially spaced apart by a preset distance. This can prevent the oil supply groove from invading an oil film section and increase centrifugal force against oil in the oil supply groove, thereby suppressing friction loss and wear between a main frame and the rotating shaft.
