Title: MUTUAL ROTATION-TYPE SCROLL COMPRESSOR HAVING BACK PRESSURE STRUCTURE APPLIED THERETO
Abstract:
The present invention relates to a mutual rotation-type scroll compressor wherein a differential pressure is maintained between inside and outside of a suction chamber, a back pressure is applied to back surfaces of end plate portions of driving and following scrolls such that the two scrolls are pressurized toward each other, thereby preventing pressure leakage of a compressed fluid, and lubricating oil can be easily supplied to the two scrolls by the back pressure. The present invention provides a mutual rotation-type scroll compressor wherein a pressure seal is placed between back surfaces of end plate portions of driving and following scrolls and the inner wall of a suction chamber in which the same are contained such that the two scrolls are pressurized toward each other by the back pressure, and oil is supplied to rotation support portions and tight contact portions of the two scrolls using the back pressure.
