Abstract
A slip sheet structure of a rotating compressor comprises a slip sheet which is arranged between an intake port and an outlet of a compressor air cylinder. The upper end face and the lower end face of the slip sheet are respectively contacted with a compressor bearing or the plane of a middle separator. The slip sheet comprises a front end flat section and a rear end segment difference section. The end face of the front end flat section is always contacted with the external diameter of a compressor piston and the rear end segment difference section is always kept inside a slip sheet groove of the compressor. The slip sheet structure of rotating compressor lowers the abrasion between a slip sheet tip and the piston and reduces the contact area between the slip sheet and the compressor bearing or the middle separator by reducing the thickness of the slip sheet, thereby reducing losing power consumption due to friction, being capable of enhancing lubrication performance and improving compressor performance.
