PRESSURE DISTRIBUTING SYSTEM OF SCROLL COMPRESSOR

摘要

PURPOSE: A pressure distributing system of a scroll compressor is provided to properly maintain the sealing force to the axial direction working to a fixing scroll, to reduce the damage caused by cool air leakage and friction and to improve the life span and the efficiency of a compressor. CONSTITUTION: The back pressure system of a scroll compressor includes:a high/low pressure separating plate(25) installed on the outer upper area of a fixing scroll(21) to separate into a venting chamber(23) of high pressure and a suction chamber(24) of low pressure by sealing as an O-shaped ring(22); a venting port(27) provided in the center of the fixing scroll(21) to connect the venting chamber(23) with a compression chamber(26); a cylinder(28) formed on a side of the fixing scroll(21); a gas inlet(29) for connecting the venting chamber(23) with the cylinder(28); a connecting slot(30) formed on the rear face of the gas inlet(29) to connect the compression chamber(26) with the cylinder(28); and a gas flow control piece(40) for controlling the gas flow.
