<p>The scroll compressor is provided with: a communicating hole (42) for feeding lubricant oil in the oil reservoir (5) to the back pressure chamber (39); another communicating hole (45) or space enabling lubricant oil in the back pressure chamber (39) to be fed to said compression space; and a throttle resistant part (45) for controlling the quantity of lubricant and fitted to the communicating hole (42). The above structure enables resistance of the passage to be higher than that of a minute space at the sliding surface of the bearing when intending to set a high-precision value of passage resistance with a small flow quantity of oil, whereby lubricant oil in large quantity is prevented from flowing into the space for compression operation and a highly reliable scroll compressor excellent in compression efficiency, stable in consumption of power, and free of risk to compress oil in the compression operation space with lubricant oil can be provided.</p> |
