SEALING STRUCTURE OF SCROLL COMPRESSOR

摘要

PURPOSE: A sealing structure of a scroll compressor is provided to prevent leakage of refrigerant, and to improve performance of the compressor by moving a floating plate up and down according to back pressure between a high/low pressure separation plate and a fixing scroll member. CONSTITUTION: A floating plate(50) is fastened between the lower part of a high/low pressure separation plate and the upper part of a fixing scroll member by an assembling pin(60), and double lip seal members(70,71) are formed inside and outside the floating plate. A flex body(72) is placed between double lip seal members, and the floating plate comprises two plates(51,52). An O-ring is inserted between the high/low pressure plate and the upper plate. Leakage of refrigerant in the back pressure chamber is prevented, and performance of the compressor is improved by moving the floating plate up and down according to back pressure between the pressure separation plate and the fixing scroll member.
