Abstract

PURPOSE:To keep oil in the oil reservoir of the scroll compressor in constant by a method wherein an oil returning pipe, communicating an Oldham's chamber with the oil reservoir, is provided so as to be capable of returning the oil in the Oldham's chamber into the oil reservoir at all times. CONSTITUTION:The pressure of the oil reservoir 23 is lower than the same of a motor chamber 19, therefore, the pressure difference between the Oldham's chamber 11 and the oil reservoir 23 is smaller than the same between the Oldham's chamber 11 and the motor chamber 19. Accordingly, the pressure difference between both ends of the oil returning pipe 28 becomes smaller than the same in a conventional compressor. The oil level 29 of the oil returning pipe 28 is not arriving at the Oldham's chamber 11 and the oil level 29 is stabilized even if the oil is returned from the Oldham's chamber 11, therefore, the amount of oil in the oil reservoir 23 may be kept in constant at all times.
