ABSTRACT:
A compressor includes a communication hole 42 through which lubrication oil in an oil reservoir 5 is supplied to a back pressure chamber 39 at least through an eccentrically driving bearing 15, and a communication bore 45 or gap through which the lubrication oil in the back pressure chamber 39 is fed into compression spaces, and a constricted resistance member 44 for regulating the oil flow rate is provided on the communication hole 42. The passage resistance can be made larger in comparison with the case where resistance is caused in a small space of a sliding portion of a bearing, and an accurate value of the passage resistance can be preset with the oil flow rate being low, thereby preventing flow of the lubrication oil to the compression operating spaces from increasing in quantity. Thus, there is provided a highly reliable scroll compressor which has a high compression efficiency, consumes power constantly, and has no risk of compression of the lubrication oil in the compression operating spaces.
